Chapter 1

Overview

1.1 Introducing the M690T

The M690T is a seventh generation Integrated Graphics Processor (IGP) that integrates a DirectX® 9.0 compliant 2D/3D

graphics core and a system controller in a single chip. It supports the AMD Athlon™ 64, Athlon 64 FX, Athlon 64 X2,

AMD Sempron™, and AMD Turion™ 64 processors, including both AM2 and S1 socket CPUs. All CPUs are supported

on both high performance and value platforms.

The M690T integrates an ATI Radeon™ X1200 graphics engine, dual display, a TV encoder, an LVDS interface, an

integrated TMDS controller, and Northbridge functionality in a single BGA package. This high level of integration and

scalability enables manufacturers to offer enthusiast level capabilities and performance while minimizing board space and

system cost.

Robust and Flexible Core Logic Features

The M690T combines graphics and system logic functions in a single chip using a 21mm-body FCBGA package,

reducing overall solution area. For optimal system and graphics performance, the M690T supports a high speed

HyperTransport™ interface to the AMD processor, running at a data rate of up to 2GT/s and supporting the new

generation of AM2 and S1 socket processors. The M690T is ideally suited to 64-bit operating systems, and supports

platform configurations with greater than 4GB of system memory. The rich PCI Express® expansion capabilities of

M690T, including support for PCI Express external graphics and up to four other PCI Express peripherals, are

complemented by the advanced I/O features of AMD's SB600 Southbridge.

Best for Windows VistaTM

The M690T delivers the best Windows Vista™ experience of any integrated graphics and core logic product for the AMD

platform. It incorporates an ATI Radeon™ X700-based graphics core, which provides the 3D rendering power needed to

generate the Windows Vista desktop even under the most demanding circumstances. In addition, dedicated hardware

acceleration is provided for key new Windows Vista features such as ClearType®. This ATI Radeon X700-based graphics

technology also enables great 3D application performance through SmartShader™ HD, SmoothVision™ HD, and 3Dc™

technologies.

Leading Multimedia Capabilities

The M690T incorporates the innovative ATI Avivo™* display architecture, providing users with visual quality which is

second to none. Advanced scaling and color correction capabilities, along with increased precision through the entire

display pipeline, ensure an optimal image on CRT monitors, LCD panels, and any other display devices. A new TV

encoder, based on designs used in AMD's Xilleon™ products, provides unequalled quality, and a TMDS interface,

configurable to support DVI/HDMI and HDCP, allows compatibility with even the most modern high definition

televisions without the additional cost of external components.

*Note: ATI Avivo™ is a technology platform that includes a broad set of capabilities offered by certain ATI Radeon

products. Full enablement of some ATI Avivo™ capabilities may require complementary products.

Low Power Consumption and Industry Leading Power Management

The M690T is manufactured using a power efficient 80nm technology, and it supports a whole range of industry standards

and all new proprietary power management features. In addition to comprehensive support for the ACPI specification and

AMD features such as AMD PowerNow!™, the ATI PowerPlay™ technology (enhanced with new adaptive frame buffer

compression and ATI PowerShift™ features) minimizes the M690T's power consumption by adjusting graphics core

performance and core voltage to the task and usage environment.

Software Compatibility

The graphics driver for the M690T is fully compatible with all other ATI Radeon class graphics controllers from AMD. A

single driver can support multiple graphics configurations across AMD's product lines, including the ATI Radeon family

1-2 Proprietary

M690E

and the AMD chipset family. In addition, this driver compatibility allows the M690T to benefit immediately from AMD's

software optimization and from the advanced Windows® XP and Windows Vista support available in the ATI Radeon

family drivers.

Note: In some reference documents, the M690T is referred to by its code name "RS690T," which signifies the same

device.

1.2 M690E

The M690T and M690E are the same device with respect to their form, fit, and functionally, except for the differences

described in Appendix B, “AMD M690E.” All information in this databook, unless superseded by the information given in

Appendix B, is applicable to the M690E.

1.3 M690T Features

1.3.1 CPU HyperTransport™ Interface

•Supports the mobile and desktop Athlon 64/Athlon 64 FX/Athlon X2/AMD Sempron/AMD Turion 64 processors,

including both AM2 and S1 socket CPUs.

•Supports 200, 400, 600, 800, and 1000MHz HyperTransport (HT) interface speeds.

•Supports LDTSTP interface, CPU throttling, and stutter mode.

1.3.2 Memory Interface

•Supports an optional dedicated local frame buffer (side-port) of up to 128MB through a 16-bit interface.

•New highly flexible memory architecture allows asymmetric side-port and shared system memory frame buffer sizes.

•New dynamic memory allocation scheme improves performance and reduces power simultaneously.

•Support for DDR2 system memories up to DDR2-800, with a maximum memory clock speed of 400MHz. Memory

clock is independent of any other clock source and can therefore be set to any frequency equal to or less than

400MHz (DDR2-800), allowing the use of lower speed side-port memories.

•Support for 16Mx16, 32Mx8, 32Mx16, 64Mx8, and 64Mx16 memory devices.

1.9 Conventions and Notations

The following conventions are used throughout this manual.

1.9.1 Pin Names

Pins are identified by their pin names or ball references. Multiplexed pins assume alternate “functional names” when they

perform their alternate functions, and these “functional names” are given in Chapter 3, “Pin Descriptions and Strap

Options.”

All active-low signals are identified by the suffix ‘#’ in their names (e.g., LDTSTOP#).

1.9.2 Pin Types

The pins are assigned different codes according to their operational characteristics. These codes are listed in Table 1-3.

1.9.3 Numeric Representation

Hexadecimal numbers are appended with “h” (Intel assembly-style notation) whenever there is a risk of ambiguity. Other

numbers are in decimal.

Pins of identical functions but different trailing integers (e.g., “CPU_D0, CPU_D1,... CPU_D7”) are referred to

collectively by specifying their integers in square brackets and with colons (i.e., “CPU_D[7:0]”). A similar short-hand

notation is used to indicate bit occupation in a register. For example, NB_COMMAND[15:10] refers to the bit positions

10 through 15 of the NB_COMMAND register.

1.9.4 Register Field

A field of a register is referred to by the format of [Register Name].[Register.Field]. For example,

“NB_MC_CNTL.DISABLE_BYPASS” is the “DISABLE_BYPASS” field of the register “NB_MC_CNTL.”

Host Interface

2.1 Host Interface

The M690T is optimized to interface with the Athlon 64/Athlon 64 FX/Athlon X2/AMD Sempron/AMD Turion 64

processors, including both AM2 and S1 socket CPUs. This section presents an overview of the HyperTransport™

interface. For a detailed description of the interface, please refer to the HyperTransport I/O Link Specification from the

HyperTransport Consortium. Figure 2-2, “Host Interface Block Diagram,” illustrates the basic blocks of the host bus

interface of the M690T.

Figure 2-2 Host Interface Block Diagram

The HyperTransport (HT) Interface, formerly known as the LDT (Lightning Data Transport) interface, is a high speed,

packet-based link implemented on two unidirectional buses. It is a point-to-point interface where data can flow both

upstream and downstream at the same time. The commands, addresses, and data travel in packets on the HyperTransport

link. Lengths of packets are in multiples of four bytes. The HT link consists of three parts: the physical layer (PHY), the

data link layer, and the protocol/transaction layer. The PHY is the physical interface between the M690T and the CPU.

The data link layer includes the initialization and configuration sequences, periodic redundancy checks,

connect/disconnect sequences, and information packet flow controls. The protocol layer is responsible for maintaining

strict ordering rules defined by the HT protocol.

The M690T HyperTransport bus interface consists of 17 unidirectional differential data/control pairs and two differential

clock pairs in each of the upstream and downstream direction. On power up, the HT link is 8 bits wide and runs at a

default speed of 200MT/s. After negotiation, carried out by the HW and SW together, the link width can be brought up to

16 bits and the interface can run up to 2GT/s. The interface is illustrated in Figure 2-3, “M690T Host Bus Interface

Signals,” on page 2-3. The signal name and direction for each signal is shown with respect to the processor. Please note

that the signal names may be different from those used in the pin listing of the M690T. Detailed descriptions of the signals

are given in section 3.3, “CPU HyperTransport™ Interface‚’ on page 3-5.

Side-port Memory Interface

2.2 Side-port Memory Interface

In order to significantly decrease system power and increase graphics performance, the M690T provides an optional

side-port memory interface for dedicated frame buffer memory, to be used exclusively for the integrated graphics core.

The side-port memory interface can significantly reduce system power by allowing the CPU to stay in its lowest power

state during periods of inactivity. Screen refreshes are fetched from the side-port memory, and there is no need to "wake

up" the CPU to fetch screen refresh data.

The M690T memory controller is unique and highly optimized. It operates in 16-bit mode at very high speed (up to

DDR2-800), and has a new programmable interleaved mode that significantly increases the memory bandwidth and

reduces data latency to the integrated graphics core. The additional bandwidth provided to the internal graphics core will

also aid the M690T in reaching and exceeding Microsoft's Windows VistaTM Premium logo requirements.

2.2.1 DDR2 Memory Interface

Figure 2-4, “M690T Side-port Memory Interface,” on page 2-4, illustrates the side-port memory interface of the M690T.

The M690T memory controller supports up to 128MB of dedicated side-port frame buffer memory. It controls a single

rank of DDR2 devices in 16-bit memory configuration. It supports device sizes of 256, 512, and 1024 Mbit, and device

widths of x8 and x16. Because the memory controller supplies only one chip select signal, only DDR2 devices with one

chip select are supported. A wide range of DDR2 timing parameters, configurations, and loadings are programmable via

the M690T memory controller configuration registers

LVDS Interface

2.3 LVDS Interface

The M690T contains a dual-channel 24-bit LVDS interface. Notice that for designs implementing only a single LVDS

channel, the LOWER channel of the interface should be used.

2.3.1 LVDS Data Mapping

Figure 2-5 below shows the transmission ordering of the LVDS signals on the lower and the upper data channels.

The signal mappings for single and dual channel transmission are shown in Table 2-3 and Table 2-4 respectively.

2.3.2 LVDS Spread Spectrum

The M690T has an internal LVDS spread spectrum controller capable of generating a frequency modulated profile for the

LVDS signals. The amount of spread (center spread of up to +/-2.5% and down spread of up to 5%) and the modulation

frequency (in the range of 20-50kHz) are programmable through the LVDS registers.

2.4.1 DVI/HDMI Data Transmission Order and Signal Mapping

The M690T also contains a dual-link TMDS interface, multiplexed on the PCI Express® (PCI-E) graphics lanes. Figure

2-6 below shows the transmission ordering of the signals on the interface. The multiplexing relationships between the

PCI-E external graphics signals and the TMDS signals are given in section 3.10, “TMDS Interface Multiplexed on the PCI

Express® Graphics Lanes‚’ on page 3-10.

Figure 2-6 Data Transmission Ordering for the TMDS Interface

For dual-link mode, which is for DVI only, the same transmission order applies to data channels on the second link, with

the first link transmitting data for even pixels and the second link for odd pixels. See Table 2-6, “Dual-Link Signal

Mapping for DVI,” on page 2-11 for details.

The signal mapping for the transmission is shown in Table 2-5, “Single-Link Signal Mapping for DVI/HDMI,” on page

2-10, and Table 2-6, “Dual-Link Signal Mapping for DVI,” on page 2-11.

Notes:

1 Tested over the operating temperature range at nominal supply voltage, with an Iref of -1.50mA (Iref is the level of the current flowing

out of the RSET resistor).

2 Tested over the operating temperature range at reduced supply voltage, with an Iref of -1.50mA (Iref is the level of the current flowing

out of the RSET resistor).

3 Full scale error from the value predicted by the design equations.

4 About the mid-point of the distribution of the three DACs measured at full scale deflection.

5 Linearity measured from the best fit line through the DAC characteristics. Monotonicity guaranteed.

6 Load = 37.5Ω + 20pF with Iref = -1.50 mA (Iref is the current flowing out of the RSET resistor).

7 Measured from the end of the overshoot to the point where the amplitude of the video ringing is down to +/-5% of the final steady state

value.

8 This parameter is sampled, not 100% tested.

9 Monotonicity is guaranteed.

2.6 External Clock Chip

On the M690T platform, an external clock chip provides the reference clock to the CPU (for generating the CPU internal

clocks) and a reference clock to the M690T (for generating the HyperTransport, PCI Express, and A-Link Express II

clocks). For more information about supported clock chips, please consult your AMD CSS representative.

LVDS_BLON I/O VDDR3 VSS

50kΩ

programmable:

PU/PD/none

Digital panel backlight brightness control. Active high. It controls

backlight on/off or acts as PWM output to adjust brightness.

If LVTMA_BL_MOD_CNTL.LVTMA_BL_MOD_EN = 0, the pin

controls backlight on/off. Otherwise, it is the PWM output to adjust

the brightness.

LVTMA_BL_MOD_CNTL.LVTMA_BL_MOD_LEVEL can be used

to control the backlight level (256 steps) by means of pulse width

modulation. The duty cycle of the backlight signal can be set

through the LVTMA_BL_MOD_CNTL.LVTMA_BL_MOD_LEVEL

bits. For example, setting these bits to a value of 32 will set the

on-time to 32/256*(1/f) and the off-time to (256-32)/256*(1/f),

where f is the XTALIN frequency and is typically 14.318MHz.

Note that the PWM frequency is set by

LVTMA_BL_MOD_CNTL.LVTMA_BL_MOD_RES and

LVTMA_PWRSEQ_REF_DIV.LVTMA_BL_MOD_REF_DIV. The

PWM frequency

= f/((BL_MOD_REF_DIV+1)*(BL_MOD_RES+1)).

For more information, refer to the Register Reference Manual.

In CPIS mode, LVDS_BLON is VARY_BL as defined in CPIS.

PWM mode should be enabled. LVDS_BLEN should be

connected to ENA_BL, which turns the backlight AC inverter

on/off.

In order to fully support debugging of customer platforms, it is mandatory that customer designs allow access to the

signals listed in Table 3-16, “M690T Debug Port Signals” below.

For debug ports on the side-port memory signals, an acceptable implementation of an access point will be an opening in

Strapping Options

3.16 Strapping Options

The M690T provides strapping options to define specific operating parameters. The strap values are latched into internal

registers after the assertion of the POWERGOOD signal to the M690T. Table 3-17, “Strap Definitions for the M690T,”

shows the definitions of all the strap functions. These straps are set by one of the following four methods:

•Allowing the internal pull-up resistors to set all strap values to “1” automatically.

•Attaching pull-down resistors to specific strap pins listed in Table 3-17 to set their values to “0”.

•Downloading the strap values from an I2C serial EEPROM (for debug purpose only; contact your AMD CSS

representative for details).

•Setting through an external debug port, if implemented (contact your AMD CSS representative for details).

All of the straps below are defined active low. They are pulled up internally by default, so that no external pull-ups are

required to select “1”s for those straps. To select “0”s, the strap pins must be pulled down to VSS through resistors.

During reset, the strap pins are undriven, allowing either an internal pull-up to pull a pin to “1” or an external pull-down to

pull a pin to “0.” The values on the strap pins are then latched into the device and used as operational parameters.

However, for debug purposes, those latched values may be overridden through an external debug strap port or by a

bit-stream downloaded from a serial EEPROM.

4.4.1 Read Cycle DQ/DQS Delay

During a memory read cycle, there is a DLL inside the M690T that can delay each DQS signal with respect to its byte of

the DQ valid window. This delay ensures adequate setup and hold time to capture the memory data. This DLL delay is

programmable through the following registers:

MCA_DLL_SLAVE_RD_0. MCA_DLL_ADJ_DQSR_0 <NBMCIND : 0xE0[7:0]>

MCA_DLL_SLAVE_RD_1. MCA_DLL_ADJ_DQSR_1 <NBMCIND : 0xE1[7:0]>

LVDS Timing

The fraction of strobe delay, in terms of a memory clock period is (24+MCA_DLL_ADJ_DQSR) / 240. For example: if

MCA_DLL_ADJ_DQSR_1 = 36, then DQS1 is delayed by 0.25 x memory_clock_period. So, if the memory clock period

is 5ns, then DQS1 is delayed internally by 1.25ns with respect to DQ[15:8].

4.4.2 Write Cycle DQ/DQS Delay

Similar to a read cycle, during memory write cycle there is a DLL inside the M690T that can delay each DQS signal with

respect to its byte of the DQ valid window. This delay ensures adequate setup and hold time for DQ and DQS to the

memory. This DLL delay is programmable by the following registers in the same manner as with the read cycle:

MCA_DLL_SLAVE_WR_0.MCA_DLL_ADJ_DQ_B0 <NBMCIND : 0xE8[7:0]>

MCA_DLL_SLAVE_WR_1.MCA_DLL_ADJ_DQ_B1 <NBMCIND : 0xE9[7:0]>

Again, the fraction of strobe delay, in terms of a memory clock period is (24+MCA_DLL_ADJ_DQSR) / 240. For

example: if MCA_DLL_ADJ_DQ_B0 = 96, then DQS0 is delayed by 0.5 x memory_clock_period. So, if the memory

clock period is 5ns, then DQS0 is delayed internally by 2.5ns with respect to DQ[7:0].

Depending on the board layout of DQS and DQ signals, it may be necessary to have different delays for each DQS signal.

Layouts of the DQS and DQ signals should follow the rules given in the RS690/RS485-Series IGP Motherboard Design

Guide.

M690T Thermal Characteristics

5.2.2 Thermal Diode Characteristics

The M690T has an on-die thermal diode, with its positive and negative terminals connected to the THERMALDIODE_P

and THERMALDIODE_N pins respectively. Combined with a thermal sensor circuit, the diode temperature, and hence

the ASIC temperature, can be derived from a differential voltage reading (

∆

V). The equation relating T to

∆

V is given

below:

where:

∆

V = Difference of two base-to-emitter voltage readings, one using current = I and the other using current = N x I

N = Ratio of the two thermal diode currents (=10 when using an ADI thermal sensor, e.g. ADM 1020, 1030)

= Ideality factor of the diode

K = Boltzman’s Constant

T = Temperature in Kelvin

q = Electron charge

The series resistance of the thermal diode (RT) must be taken into account as it introduces an error in the reading

(for every 1.0Ω, approximately 0.8oC is added to the reading). The sensor circuit should be calibrated to offset the

RT induced, plus any other known fixed error. Measured values of diode ideality factor and series resistance for the

diode circuit are defined in the Thermal Design and Analysis Guidelines for the RS690 Product Family.

Ambient Temperature 0 — 45 °C3

Thermal Design Power — 8 — W 4

Notes:

1 - The maximum operating case temperature is the die geometric top-center temperature measured via a thermocouple based on the

methodology given in the document Thermal Design and Analysis Guidelines for the RS690 Product Family (Chapter 10). This is the

temperature at which the functionality of the chip is qualified.

2 - The maximum absolute rated junction temperature is the junction temperature at which the device can operate without causing

damage to the ASIC. This temperature can be measured via the integrated thermal diode described in the next section.

3 - The ambient temperature is defined as the temperature of the local intake air to the thermal management device. The maximum

ambient temperature is dependent on the heat sink's local ambient conditions as well as the chassis' external ambient, and the value

given here is based on AMD’s reference heat sink solution for the M690T. Refer to Chapter 7 in the Thermal Design and Analysis

Guidelines for the RS690 Product Family for heatsink and thermal design guidelines. Refer to Chapter of the above mentioned

document for details of ambient conditions.

4 - The Thermal Design Power (TDP) is defined as the worst-case power dissipation while running currently available applications at

nominal voltages and at the maximum operating temperature. Since the core power of modern ASICs using 90nm and smaller process

technology can vary significantly, parts specifically screened for higher core power were used for TDP measurement.The TDP is

intended only as a design reference. It is not an absolute maximum power under all conditions. The value shown here is a preliminary

estimate only.

5.3.2 Pressure Specification

To avoid damages to the ASIC (die or solder ball joint cracks) caused by improper mechanical assembly of the cooling

device, follow the recommendations below:

•It is recommended that the maximum load that is evenly applied across the contact area between the thermal

management device and the die does not exceed 6 lbf. Note that a total load of 4-6 lbf is adequate to secure the

thermal management device and achieve the lowest thermal contact resistance with a temperature drop across

the thermal interface material of no more than 3°C. Also, the surface flatness of the metal spreader should be

0.001 inch/1 inch.

•Pre-test the assembly fixture with a strain gauge to make sure that the flexing of the final assembled board and

the pressure applying around the ASIC package will not exceed 600 micron strain under any circumstances.

•Ensure that any distortion (bow or twist) of the board after SMT and cooling device assembly is within industry

guidelines (IPC/EIA J-STD-001). For measurement method, refer to the industry approved technique described

in the manual IPC-TM-650, section 2.4.22.

5.3.3 Board Solder Reflow Process Recommendations

5.3.3.1 Stencil Opening Size for Solderball Pads on PCB

It is recommended that the stencil aperture for solderballs be kept at the same size as the land pads' except for the

nine pads at each corner of the ASIC package, for which a maximum size of 400µm is recommended (see Figure

5-5 below). This recommendation is based on AMD’s sample land pattern design for the M690T, which is available

from your AMD CSS representative.

5.3.3.2 Reflow Profile

A reference reflow profile is given below. Please note the following when using RoHS/lead-free solder (SAC105/305/405

Tin-Silver-Cu):

•The final reflow temperature profile will depend on the type of solder paste and chemistry of flux used in the SMT

process. Modifications to the reference reflow profile may be required in order to accommodate the requirements of

the other components in the application.

•An oven with 10 heating zones or above is recommended.

•To ensure that the reflow profile meets the target specification on both sides of the board, a different profile and oven

recipe for the first and second reflow may be required.

•Mechanical stiffening can be used to minimize board warpage during reflow.

•It is suggested to decrease temperature cooling rate to minimize board warpage.

•This reflow profile applies only to RoHS/lead-free (high temperature) soldering process and it should not be used for

Eutectic solder packages. Damage may result if this condition is violated.

•Maximum 3 reflows are allowed on the same part.

Power Management and ACPI

6.1 ACPI Power Management Implementation

This chapter describes the support for ACPI power management provided by the M690T. The M690T supports ACPI

Revision 1.0b. The hardware, system BIOS, video BIOS, and drivers of the M690T have all the logic required for meeting

the power management specifications of PC2001, OnNow, and the Windows Logo Program and Device Requirements

version 2.1. Table 6-1, “ACPI States Supported by the M690T,” describes the ACPI states supported by the M690T.

Table 6-2, “ACPI Signal Definitions,” describes the signals used in the ACPI power management scheme of the M690T.

Note: Also supported are additional processor power states that are not part of the ACPI specification, e.g. C1E (C1

Enhanced) and C3 pop-up. Please refer to the SB600 Databook and the RS690 Register Programming Requirements for

more information.

Table 6-1 ACPI States Supported by the M690T

ACPI State Description

Power Management for the Graphics Controller

6.2 Power Management for the Graphics Controller

The M690T supports power management for the embedded graphics device as specified by the PCI Bus Power

Management Interface Specification version 1.0, according to which the integrated graphics core of the M690T qualifies

as a device embedding a single function in the power management system.

6.2.1 PCI Function Power States

There are up to four power states defined for each PCI function associated with each PCI device in the system. These

power states are D0, D1, D2 and D3. D0 (on) consumes the most power while D3 (off) consumes the least. D1 and D2

enable levels of power savings in between those of D0 and D3. The concepts of these power states are universal for all

functions in the system. When transitioned to a given power management state, the intended functional behavior is

dependent upon the type (or class) of the function.

6.2.2 PCI Power Management Interface

The four basic power management operations are:

•Capabilities Reporting

•Power Status Reporting

•Setting Power State

•System Wakeup

All four of these capabilities are required for each power management function with the exception of wakeup event

generation.

This section describes the format of the registers in the PCI Configuration Space that are used by these power

management operations. The Status and Capabilities Pointer (CAP_PTR) fields have been highlighted to indicate where

the PCI Power Management features appear in the standard Configuration Space Header.

6.2.3 Capabilities List Data Structure in PCI Configuration Space

The Capabilities bit in the PCI Status register (offset = 06h) indicates whether or not the subject function implements a

linked list of extended capabilities. Specifically, if bit 4 is set, the CAP_PTR register is implemented to give offset to the

first item in the Capabilities link list.

Power Management for the Graphics Controller

Proprietary 6-3

The location of the Capabilities Pointer (CAP_PTR) depends on the PCI header type. See PCI specification Revision 2.2

for specification of CAP_PTR offsets.

The graphics core implements extended capabilities of the AGP and Power Management. It needs to provide the

standardized register interface. The first entry in the chain of descriptors has to be the PMI descriptor, as this functionality

will be supported even if the M690T operates as a PCI device. The Capabilities Identifier for Power Management is 01h.

6.2.4 Register Block Definition

This section describes the PCI Power Management Interface registers. These registers are implemented inside the Host

Interface (HI) as part of the configuration space of the device (M690T).

The first 16 bits (Capabilities ID [offset = 0] and Next Item Pointer [offset = 1]) are used for the linked list infrastructure.

The next 32 bits (PMC [offset = 2] and PMCSR registers [offset = 4]) are required for compliance with this specification.

As with all PCI configuration registers, these registers may be accessed as bytes, 16-bit words, or 32-bit DWORDs. All of

the write operations to the reserved registers must be treated as no-ops. This implies that the access must be completed

normally on the bus and the data should be discarded. Read accesses to the reserved or the unimplemented registers must

be completed normally and a data value of 0000h should be returned.

Power Management for the Graphics Controller

The offset for each register is listed as an offset from the beginning of the linked list item that is determined either from

the CAP_PTR (if Power Management is the first item in the list) or the NEXT_ITEM_PTR of the previous item in the list.

6.2.5 Capability Identifier: Cap_ID (Offset = 0)

The Capability Identifier, when read by system software as 01h, indicates that the data structure currently being pointed to

is the PCI Power Management data structure. Each function of a PCI device may have only one item in its capability list

with Cap_ID set to 01h.

Figure 6-1, ‘Linked List for Capabilities,” shows the implementation of the capabilities list. The CAP_PTR gives the

location of the first item in the list. PCI Power Management registers have been stated as example in this list (although the

capabilities can be in any order).

•The first byte of each entry is required to be the ID of that capability. The PCI Power Management capability has an

ID of 01h.

•The next byte is a pointer giving an absolute offset in the functions PCI Configuration Space to the next item in the

list and must be DWORD aligned.

•If there are no more entries in the list, the NEXT_ITEM_PTR must be set to 0 to indicate an end of the linked list.

Each capability can then have registers following the NEXT_ITEM_PTR.

The definition of these registers (including layout, size, and bit definitions) is specific to each capability. The PCI Power

Management Register Block is defined in Figure 6-1, ‘Linked List for Capabilities,” below.

Testability

7.1 Test Capability Features

The M690T has integrated test modes and capabilities. These test features cover both the ASIC and board level testing.

The ASIC tests provide a very high fault coverage and low DPM (Defect Per Million) ratio of the part. The board level

tests modes can be used for motherboard manufacturing and debug purposes. The following are the test modes of the

M690T:

•Full scan implementation on the digital core logic that provides about 99% fault coverage through ATPG (Automatic

Test Pattern Generation Vectors).

•Dedicated test logic for the on-chip custom memory macros to provide complete coverage on these modules.

•Improved access to the analog modules and PLLs in the M690T to allow full evaluation and characterization of these

modules.

•A JTAG test mode (which is not entirely compliant to the IEEE 1149.1 standard) to allow board level testing of

neighboring devices.

•An XOR TREE test mode on all the digital I/Os to allow for proper soldering verification at the board level.

•A VOH/VOL test mode on all digital I/Os to allow for proper verification of output high and output low voltages at

the board level.

These test modes can be accessed through the settings on the instruction register of the JTAG circuitry.

XOR Tree

Pin A is assigned to the output direction, and pins 1 through 6 are assigned to the input direction. It can be seen that after

all pins 1 to 6 are assigned to logic 0 or 1, a logic change in any one of these pins will toggle the output pin A.

The following is the truth table for the XOR tree shown in Figure 7-1 The XOR start signal is assumed to be logic 1.

7.3.2 Description of the XOR Tree for the M690T

The XOR start signal is applied at the TDI pin of the JTAG circuitry and the output of the XOR tree is obtained at the

TDO pin. Refer to Section 7.3.4 for the list of the signals included on the XOR tree. There is no specific connection order

to the signals on the tree. A toggle of any of these balls in the XOR tree will cause the output to toggle.

7.3.3 XOR Tree Activation

The M690T chip enters the XOR tree test mode by means of the JTAG. First, the 8-bit instruction register of the JTAG is

loaded with the XOR instruction (“00001000”). This instruction assigns the input direction to all the pins except pin TDO,

which is assigned the output direction to serve as the output of the XOR tree. After loading, the JTAG is taken to the

Run-Test state for completion of the XOR tree initialization.

Note: 10MHz clock frequency is recommended for the XOR TREE test mode.

7.3.4 XOR Chain for the M690T

When the XOR tree is activated, any pin on the XOR tree must be either pulled down or pulled up to the I/O voltage of the

pin. Only pins that are not on the XOR tree can be left floating.

When differential signal pairs are listed as single entries on the XOR tree, opposite input values should be applied to the

two signals in each pair (e.g., for entry no. 13 on the tree, when “1” is applied to HT_RXCAD15P, “0” should be applied

to HT_RXCAD15N).

7.4.2 VOH/VOL Tree Activation

To activate the VOH/VOL tree and run a VOH/VOL test, perform the sequence below:

1. Supply a clock at any speed (same or faster than test pattern data rate) to the OSCIN pin as the I/O test clock source.

2. Set POWERGOOD to 0.

3. Set TESTMODE to 1.

4. Set DACSDA to 0.

5. Load JTAG instruction register with the instruction 0110 0011.

6. Load JTAG instruction register with the instruction 0010 0111.

7. Set POWERGOOD to 1.

8. Load JTAG instruction register with the instruction 1001 1001.

9. Run test by loading JTAG data register with data 0000 0000 0000 00xy, where bit x is the input value for

TEST_ODD and bit y that for TEST_EVEN (see Table 7-4 above).

10. To end test, load JTAG instruction register with the instruction 0101 1101.

7.4.3 VOH/VOL Pin List

Table 7-5 below shows the M690T VOH/VOL tree. There is no specific order of connection. Under the Control column,

an “ODD” or “EVEN” indicates that the logical output of the pin is same as the “TEST_ODD” or “TEST_EVEN” input

respectively.

When a differential pair appear in the table as a single entry, the output of the positive (“P”) pin is indicated in the Control

column (see last paragraph for explanations), and the output of the negative pin (“N”) will be of the opposite value. E.g.,

for entry no. 1 on the tree, when TEST_EVEN is 1, HT_TXCAD15P will give a value of 1 and HT_TXCAD15N will give

a value of 0.

AMD M690E

B.1 Introduction

The M690T and M690E are two members of the same AMD RS690-series Northbridge and chipset family. The M690E

and M690T have exactly the same package, pin-out, and fabrication process. All peripheral functions and features are the

same as well, except for the differences explained in Section B.2 below.

Figure B-1 M690E Branding Diagram for ASIC Revision A12

Both the M690E and M690T are packaged in the same 21mmx21mm 465-ball FCBGA package. But, the devices’

markings and part numbers are different. The part marking, planned production schedule, and AMD OPN (ordering

number) for the M690E are shown in Table B-1.

B.2 Feature Differences between the M690T and M690E

The M690E is identified and distinguished from the M690T by an e-fuse on the chip. There are no identification registers

that differentiate the two devices.

A) TV Output

The M690T provides SDTV (PAL or NTSC standard, with composite, S-Video (separate luminance and chrominance

channels), or YCbCr 480i (YUV) standard definition component output) and HDTV (YPbPr 480i, 480p, 576i, 576p,

720p, 1080i) outputs through the on-chip DACs that are shared between TV and CRT outputs. Macrovision analog TV

copy protection is supported on all its standard definition and 480p high definition TV outputs.

B-2 Proprietary

The M690E, on the other hand, does not provide any sort of analog TV output and does not support Macrovision copy

protection. Despite the lack of TV output, the DACs of the M690E can still be used to provide a high quality CRT output.

The table and figure below summarize the differences between the M690T and M690E in terms of analog TV and

VGA/CRT display outputs.

Figure B-2 M690T and M690E Analog Display Output Signals

Note: For designs using the M690E, the C, Y, and COMP pins on the package do not provide any output and should be

left unconnected on the motherboard.

B) TMDS/DVI Digital Output Multiplexed on the LVDS/TMDS (LVTM) Interface

Both the M690E and M690T support a dual-channel LVDS 24-bit output through its LVDS interface. However, on the

M690E, the interface is enhanced to also support a TMDS/DVI output in place of the LVDS format. An M690E

based-system requires a custom video BIOS to configure the enhanced LVDS/TMDS (LVTM) interface to drive out

either LVDS or TMDS/DVI signals. The video BIOS is available from AMD. The minimum version number for the

LVDS output is 10.55.0.15 and for the TMDS/DVI output is 10.55.0.31. Contact your AMD CSS representative for the
