1.3 PIN DESCRIPTION

PIN TYPE DESCRIPTION

CK, CK Input Clock: CK and CK are differential clock inputs. All address and contr o l input signals are sampled

on the crossing of the positive edge of CK and negative edge of CK. Output (read) data is refer-

enced to the crossings of CK and CK (both direc tions of cros sing).

CKE Input

Clock Enable: CKE HIGH activates, and CKE LOW deactivates internal clock signals, and device

input buffers and output drivers. Taking CKE LOW provides PRECHARGE POWER DOWN and

SELF REFRESH operation (all banks idle), or ACTIVE POWER DOWN (row ACTIVE in any bank).

CKE is synchronous for POWER DOWN entry and exit, and for SELF REFRESH entry. CKE is asyn-

chronous for SELF REFRESH exit. After VREF has become stable during the pow er on and initial-

ization sequence, it m ust be maintained for proper operation of the CKE rece iver. For proper

self-ref resh entry and exit, VREF must be maintained to this input . CKE must be maintained high

throughout RE AD and WRITE acces ses. Input buffers, excludin g CK, CK and CKE are disabled

during POWER DOWN. Input buffers, excluding CKE are disabled during SELF REFRESH.

CS Input Chip Select : All commands are masked when CS is registered HIGH. CS provides for external

bank selection on systems with multiple banks. CS is considered part of the comma nd code.

ODT Input

On Die Termination Control : ODT(registered HIGH) enables on die termination resi st ance inter-

nal to the DDR2 SDRAM. When enabled, ODT is only applied t o DQ, DQS, DQS, RDQS, RDQS ,

and DM signal for x4,x 8 configurations. For x16 conf igur atio n ODT is applied to each DQ, UDQS/

UDQS.LDQS/LDQS, UDM and LDM signal. The ODT pin will be ignored if the Extended Mode

Register(EMRS(1)) is programmed to disable ODT.

RAS, CAS, WE Input Command Inputs: RAS, CAS and WE (along with CS) define the command being entered.

DM

(LDM, UDM) Input

Input Data Mask : DM is an input mask signal for write data. Inpu t Data is mas ked when DM is

sampled High coincident with that input data during a WRITE access. DM is sampled on both

edges of DQS, Although DM pins are input only, the DM loading matches the DQ and DQS load-

ing. For x8 device, the function of DM or RDQS/ RDQS is enabled by EMRS command.

BA0 - BA2 Input

Bank Address Inputs: BA0 - BA2 define to which bank an ACTIVE, Read, Write or PRECHARGE

command is being applie d(For 256Mb and 512Mb, BA2 is not appli ed). Bank address also deter-

mines if the mode register or extended mode register is to be accessed during a MRS or EMRS

cycle.

A0 -A15 Input

Address Inputs: Provide the row address for ACTIVE commands, and the column address and

AUTO PRECHARGE bit for READ/WRITE commands to select one location out of the memory

array in the respective bank. A10 is sampled during a precharge command to determine

whether the PRECHARGE applies to one bank (A10 LOW) or all banks (A10 HIGH). If only one

bank is to be precharg ed, the bank is select ed by BA0- BA2. The addres s inputs also pr ovide the

op code during MODE REGISTER SET commands.

Output

Data Strobe : Output with read data, input with write data. Edge aligned with read data, cen-

tered in write data. For the x16, LDQS correspond to the data on DQ0~DQ7; UDQS corresponds

to the data on DQ8~ DQ15. For the x8, an RDQS option using DM pin can be enabl e d via the

EMRS(1) to simplify read timing. The data strobes DQS, LDQS, UDQS, and RDQS may be used in

single ended mode or paired with optional complementary signals DQS, LDQS ,UDQS and RDQS

to provide dif ferential pair signaling to the sy stem during both reads and wirtes. An EMRS(1)

control bit enables or disables all complementary data strobe signals.

General notes, which may apply for all AC parameters

1. Slew Rate Measurement Levels

a. Output slew rate for falling and rising edges is measured between VTT - 250 mV and VTT + 250 mV for single ended signals.

For differential signals (e.g. DQS - DQS) output slew rate is measured between DQS - DQS = -500 mV and DQS - DQS = +500mV.

Output slew rate is guaranteed by design, but is not necessarily test ed on each device.

b. Input slew rate for single ended signals is measured from dc-level to ac-level: from VIL(dc) to VIH(ac) for rising edges and from

VIH(dc) and VIL(ac) for falling edges.

For differenti al signals (e.g. CK - CK) slew rate for rising edges is measured from CK - CK = -250 mV to CK - CK = +500 mV(250mV

to -500 mV for falling egdes).

c. VID is the magnitude of the dif ference bet ween the input voltage on CK and the input voltage on CK, or between DQS and DQS for

differential strobe.

2. DDR2 SDRAM AC timing reference load

The following figure represents the timing reference load used in defining the relevant timing parameters of the part. It is not

intended to be either a precise representation of the typical system environment nor a depiction of the actual load presented by a

production tester. System designers will use IBIS or other simulation tools to correlate the timing reference load to a system environ-

ment. Manufacturers will correlate to their production test conditions (generally a coaxial transmission line terminated at the tester

electronics).

The output timing reference voltage level for single ended signals is the crosspoint with VTT. The output timing reference voltage

level for differential signals is the crosspoi nt of the true (e.g. DQS) and the complement (e.g. DQS) signal .

3. DDR2 SDRAM output slew rate test load

Output slew rate is characterized under the test conditions as shown below.

4. Differential data strobe

DDR2 SDRAM pin timings are specified for either single ended mode or differential mode depending on the setting of the EMRS

“Enable DQS” mode bit; timing advantages of differential mode are realized in system design. The method by which the DDR2

SDRAM pin timings are measured is mode dependen t. In single

VREF. In differential mode, these timing relationships are measur ed relative to t he crosspoi n t o f DQS and its c omplement, DQS . Thi s

distinction in timing method s is guaranteed by design and characterization. Note that when differential data strobe mode is disabled

via the EMRS, the complementary pin, DQS, must be tied externally to VSS throug h a 20 ohm to 10 K ohm resisto r to i n sure proper

operation.

5. AC timings are for linear signal transitions. See System Derating for other signal transitions.

6. These parameters guarantee device behavior, but they are not necessarily tested on each device.

They may be guaranteed by device design or tester correlation.

7. All voltages referenced to VSS.

8. Tests for AC timing, IDD, and electrical (AC and DC) characteristics, may be conducted at nominal reference/

supply voltage levels, but the related specifications and device operation are guaranteed for the full voltage

range specified.

Specific Notes for dedicated AC parameters

1. User can choose which active power down exit timing to use via MRS(bit 12). tXARD is expected to be used for fast active

power down exit timing. tXARDS is expected to be used for slow active power down exit timing where a lower power value is

defined by each vendor data sheet.

2. AL = Additive Latency

3. This is a minimum requirement. Minimum read to precharge timing is AL + BL/2 providing the tRTP and tRAS(min) have been

satisfied.

4. A minimum of two clocks (2 * tCK) is required irrespective of operating frequency

5. Timings are guaranteed with command/address input slew rate of 1.0 V/ns. See System Derating for other slew rate values.

6. Timings are guaranteed with data, mask, and (DQS/RDQS in singled ended mode) input slew rate of 1.0 V/ns. See System

Derating for other slew rate values.

7. Timings are guaranteed with CK/CK differential slew rate of 2.0 V/ns. Timings are guaranteed for DQS signals with a

differen tial slew rate of 2.0 V/ns in differential strobe mode and a slew rate of 1V/ns in single ended mode. See System

Derating for other slew rate values.

8. tDS and tDH derating table (for DDR2- 400 / 533)

1) For all input signals the total tDS(setup time) and tDH(hold time) required is calculated by adding the datasheet value to the derating

value listed in above Table.

Setup(tDS) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of VREF(dc) and the first crossing

of Vih(ac)min. Setup(tDS) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of VREF(dc) and

the first crossing of Vil(ac)max. If the actual signal is always earlier than the nominal slew rate line between shaded ‘ VREF(dc) to ac

region’, use nominal slew rate for derating value(see Fig a.) If the actual signal is later than the nominal slew rate line anywhere

between shaded ‘VREF(dc) to ac region’, the slew rate of a tangent line to the actual signal from the ac level to dc level is used for

derating value(see Fig b.)

Hold(tDH) nominal slew rate for a rising signal is defined as the slew rate rate between the last crossing of Vil(dc) max and the first

crossing of VREF(dc). Hold (tDH) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of Vih(dc)

min and the fi rst cr ossi ng of V REF( dc). If the actual signal is earlier than the nominal slew rate line anywhere between shaded ‘dc to

VREF(dc) region’, the slew rate of a tangent line to the actual signal from the dc level to VREF(dc) level is used for derating value(see

Fig d.)

Although for slow slew rates the total setup time might be negative(i.e. a valid input signal will not have reached VIH/IL(ac) at the

For slew rate in between the values listed in table x, the derating valued may obtained by li near interpolation.

These values are typically not subject to production test. They are verified by design and characterization.

Hold(tDH) nominal slew rate for a rising signal is defined as the slew rate rate between the last crossing of Vil(dc) max and the first

crossing of VREF(dc). Hold (tDH) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of Vih(dc)

min and the fi rst cr ossi ng of V REF( dc). If the actual signal is earlier than the nominal slew rate line anywhere between shaded ‘dc to

VREF(dc) region’, the slew rate of a tangent line to the actual signal from the dc level to VREF(dc) level is used for derating value(see

Fig d.)

Although for slow slew rates the total setup time might be negative(i.e. a valid input signal will not have reached VIH/IL(ac) at the

time of the rising cl ock transition) a valid inp ut signal is still required to complete the transition and reach VIH/IL(ac).

For slew rate in between the values listed in table x, the derating valued may obtained by li near interpolation.

These values are typically not subject to production test. They are verified by design and characterization.

1) For all input signals the total tIS(setup time) and tIH(hold) time) required is calculated by adding the datasheet value to the derating

value listed in above Table.

Setup(tIS) nominal sl ew r at e fo r a risi ng signal is de fi ned as t he s lew r ate between the last cros sing of VREF(dc) an d the firs t cro ssing

of VIH(ac)min. Setup(tIS) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of VREF(dc) and

the first crossing of VIL(ac)max. If the actual signal is always earlier than the nominal slew rate for line between shaded ‘VREF(dc) to

ac region’, use nominal slew rate for derating value(see fig a.) If the actual signal is later than th e nominal slew rate line anywhere

between shaded ‘VREF(dc) to ac region’, the slew rate of a tangent line to the actual signal from the ac level to dc level is used for der-

ating value(see Fig b.)

Hold(tIH) nominal slew rate for a risi ng signal is defi ned as th e slew r ate between the last cro ssing of VI L(dc)max an d the fir st cross-

ing of VREF(dc). Hold(tIH) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of VREF(dc). If the

actual signal signal is always later than th e nom inal slew rate line between shaded ‘dc to VREF(dc) region’, use nominal slew rate for

derating value(see Fig.c) If the actual signal is earlier than the nominal slew rate line anywhere between shaded ‘dc to VREF(dc)

region’, the slew rate of a tangent line to the actual signal from the dc level to VREF(dc) level is used for derating value(see Fig d.)

Although for slow rates the total setup time might be negative(i.e. a valid i nput sig nal will no t have reached VIH/IL(ac) at the time of

the rising clock transition) a valid input signal is still required to complete the transition and reach VIH/IL(ac).

For slew rates in between the values listed in table, the derating values may obtained by linear interpolation.

These values are typically not subject to production test. They are verified by design and characterization.

10. The maximum limit for this parameter is not a devic e li m it . The device will operate with a greater value for this parameter, but

system performance (bus turnaround) will degrade accordingly.

11. MIN ( t CL, t CH) refers to the smaller of the actual clock low time and the actual clock high time as provided to the device

(i.e. this value can be greater than the minim um sp ecification limits for t CL and t CH). For example, t CL and t CH are = 50%

of the period, less the half period jitter ( t JIT(HP)) of the clock source, and less the half period jitter due to crosstalk ( t

JIT(crosstalk)) into the clock traces.

12. t QH = t HP – t QHS, where:

tHP = minimum half clock period for any given cycle and is defined by clock high or cl oc k lo w ( tCH, tCL).

tQHS accounts for:

1) The pulse duration distortion of on-chip clock circuits; and

2) The worst case push-out of DQS on one transition followed by the worst case pull-in of DQ on the next transition, both

of which are, separately, due to data pin skew and ou tput pattern effects, and p-channel to n-channel variation of the

output drivers.

13. tDQSQ: Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers as

well as output slew rate mismatch between DQS/ DQS and associated DQ in any given cycle.

14. DAL = WR + RU{tRP(ns)/tCK(ns)}, where RU stands for round up. WR refers to the tWR parameter stored in the MRS. For

tRP, if the result of the division is not already an integer, round up to the next highest integer. tCK refers to the application

clock period.

Example: For DDR533 at tCK = 3.75ns with tWR programmed to 4 clocks.

tDAL = 4 + (15ns/3.75ns) clocks = 4+(4) clocks = 8 clocks.

15. The clock frequency is allowed to change during self–ref resh mode or precharge power-down mode. In case of clock

frequency change during precharge power-down, a specific procedure is required as described in section 2.9.

16. ODT turn on time min is when the device leaves high impedance and ODT resistance begins to turn on.

ODT turn on time max is when the ODT resistance is fully on. Both are measured from tAOND.

17. ODT turn off time min is w hen the device starts to turn off ODT resistance.

ODT turn off time max is when the bus is in high impedance. Both are measured from tAOFD.

18. tHZ and tLZ transitions occur in the same access time as valid data t ransitions. Thesed parameters are referenced to a

specific voltage level which specifies when the device output is no longer driving(tHZ ) , or begins drivin g (tLZ). Below figure

shows a method to calculate the point when device is no longer driving (tHZ), or begins driving (tLZ) by measuring the signal

at two different voltages. The actual voltage measurement points are not critical as long as the calcul ation is consist e n et.

19. tRPST end po int and tRPRE begin point are not referenced to a specific voltage level but specify when the device output is no

longer driving (tRPST), or begins driving (tRPRE). Below figure shows a method to calculate these points when the device is

no longer driving (tRPST), or begins driving (tRPRE). Below Figure sh ow s a m e thod to calculate these points when th e device

is no longer driving (tRPST), or begins driving (tRPRE) by measuring the signal at two different voltages. The actual voltage

measurement points are not critical as long as the calculation is consistent.

20. Input waveform timing with differential data strobe enabled MR[bit10] =0, is referenced from the input signal crossing at the

VIH(ac) level to the differential data strobe crosspoint for a rising signal, and from the input sign al crossing at the VIL(ac) level

to the differential data strobe crosspoint for a falling signal applied to the device under test.

21. Input waveform timing with differential data strobe enabled MR[bit10]=0, is referenced from the input signal crossing at the

VIH(dc) level to the differential data strobe crosspoint for a risin g s ignal and VIL(dc) to the differential data strobe crosspoint

for a falling signal applied to the device u n der test.

22. Input waveform timing is referenced from the input signal crossing at the VIH(ac) level for a rising signal and VIL(ac) for a falling

signal applied to the devi ce under test.

23. Input waveform timing is referenced from the input signal crossing at the VIL(dc) level for a rising signal and VIH(dc) for a falling

signal applied to the devi ce under test.

24. tWTR is at least two clocks (2*tCK) independent of operation frequency.

25. Input waveform timing with single-ended data stro be enabl e d MR[bit10] = 1, is referenced from th e input signal crossing at the

VIH(ac) level to the single-ended data strobe crossing VIH/L(dc) at the start of its transition f or a rising signal, and from the input si g-

nal crossing at the VIL(ac) level to t he single-ended data strobe crossi ng VIH/L(dc) at the start of its transition for a falling signal

applied to the device under test. The DQS signal must be monotonic between VIL(dc)max and VIH(dc) min.

26. Input waveform timing with single-ended data stro be enabl e d MR[bit10] = 1, is referenced from the input sign al crossing at the

VIH(dc) level to the single-ended data strobe crossing VIH/L(ac) at the end of its transition for a rising signal, and fr om the input sig-

nal crossing at the VIL(dc) level to the single-ended data strobe crossing VIH/L(ac) at the end of its transition for a falling signal

applied to the device under test. The DQS signal must be monotonic between VIL(dc) max and VIH(dc) min.

27. tCKE min of 3 clocks means CKE must be registered on three consecutive positive clock edges. CKE must remain at the valid input

level the entire time it takes to achieve the 3 clocks of registration. Thus, after any CKE transition, CKE may not transition from its

valid level during the time period of tIS + 2*t C K + tIH.
