Preliminary Data Sheet M15825EJ1V0DS 5 PD44165084, 44165184, 44165364 Pin Identification Symbol Ax /R /W /NWx /BWx K , /K C, /C Description Synchronous Address Inputs: These inputs are registered and must meet the setup and hold times around the rising edge of K. Balls 9A, 3A, 10A, and 2A are reserved for the next higher-order address inputs on future devices. All transactions operate on a burst of four words (two clock period of bus activity). These inputs are ignored when device is deselected. Synchronous Read: When LOW this input causes the address inputs to be registered and a READ cycle to be initiated. This input must meet setup and hold times around the rising edge of K and is ignored on the subsequent rising edge of K. Synchronous Write: When LOW this input causes the address inputs to be registered and a WRITE cycle to be initiated. This input must meet setup and hold times around the rising edge of K and is ignored on the subsequent rising edge of K. Synchronous Byte Writes (Nybble Writes on x8): When LOW these inputs cause their respective byte or nybble to be registered and written during WRITE cycles. These signals must meet setup and hold times around the rising edges of K and /K for each of the two rising edges comprising the WRITE cycle. See pin assignment figures for signal to data relationships. Input Clock: This input clock pair registers address and control inputs on the rising edge of K, and registers data on the rising edge of K and the rising edge of /K. /K is ideally 180 degrees out of phase with K. All synchronous inputs must meet setup and hold times around the clock rising edges. Output Clock: This clock pair provides a user controlled means of tuning device output data. The rising edge of C is used as the output timing reference for first and third output data. The rising edge of /C is used as the output reference for second and fourth output data. Ideally, /C is 180 degrees out of phase with C. C and /C may be tied HIGH to force the use of K and /K as the output reference clocks instead of having to provide C and /C clocks. If tied HIGH, C and /C must remain HIGH and not be toggled during device operation. /DLL DLL Disable: When LOW, this input causes the DLL to be bypassed for stable low frequency operation. ZQ Output Impedance Matching Input: This input is used to tune the device outputs to the system data bus impedance. DQ and CQ output impedance are set to 0.2 x RQ, where RQ is a resistor from this bump to ground. Alternately, this pin can be connected directly to VDD, which enables the minimum impedance mode. This pin cannot be connected directly to GND or left unconnected. IEEE 1149.1 Test Inputs: 1.8V I/O levels. These balls may be left Not Connected if the JTAG function is not used in the circuit. IEEE 1149.1 Clock Input: 1.8V I/O levels. This pin must be tied to VSS if the JTAG function is not used in the circuit. TMS TDI TCK VREF HSTL Input Reference Voltage: Nominally VDDQ/2. Provides a reference voltage for the input buffers. D0 to Dxx Synchronous Data Inputs: Input data must meet setup and hold times around the rising edges of K and K# during WRITE operations. See pin assignment figures for ball site location of individual signals. x8 device uses D0-D7. Remaining signals are NC. x18 device uses D0-D17. Remaining signals are NC. x36 device uses D0-D35. NC signals are read in the JTAG scan chain as the logic level applied to the ball site. Synchronous Echo Clock Outputs. The rising edges of these outputs are tightly matched to the synchronous data outputs and can be used as a data valid indication. These signals run freely and do not stop when Q tristates. CQ, /CQ TDO IEEE 1149.1 Test Output: 1.8V I/O level. Q0 to Qxx Synchronous Data Outputs: Output data is synchronized to the respective C and /C or to K and /K rising edges if C and /C are tied HIGH. This bus operates in response to /R commands. See pin assignment figures for ball site location of individual signals. x8 device uses Q0-Q7. Remaining signals are NC. x18 device uses Q0-Q17. Remaining signals are NC. x36 device uses Q0-Q35. NC signals are read in the JTAG scan chain as the logic level applied to the ball site. VDD Power Supply: 1.8V nominal. See DC Electrical Characteristics and Operating Conditions for range. VDDQ Power Supply: Isolated Output Buffer Supply. Nominally 1.5V. 1.8V is also permissible. See DC Electrical Characteristics and Operating Conditions for range. VSS Power Supply: Ground NC No Connect: These signals are internally connected and appear in the JTAG scan chain as the logic level applied to the ball sites. These signals may be connected to ground to improve package heat dissipation. 6 Preliminary Data Sheet M15825EJ1V0DS PD44165084, 44165184, 44165364 Block Diagram [PD44165084] 19 ADDRESS /R ADDRESS /W 19 REGISTRY & LOGIC K /W MUX /NW0 MEMORY ARRAY 16 Q0 - Q7 OUTPUT BUFFER 16 16 OUTPUT SELECT & LOGIC OUTPUT REGISTER REGISTRY /R 2 x 32 SENSE AMPS D0 - D7 19 WRITE DRIVER 8 DATA WRITE REGISTER /NW1 8 16 16 2 CQ, /CQ MUX K K /K C C, /C OR K, /K [PD44165184] 18 ADDRESS /R ADDRESS /W 18 REGISTRY & LOGIC K /W MUX /BW0 36 36 MEMORY ARRAY 36 OUTPUT BUFFER 36 36 OUTPUT SELECT & LOGIC 18 OUTPUT REGISTER REGISTRY /R 2 x 72 SENSE AMPS D0 - D17 18 WRITE DRIVER 18 DATA WRITE REGISTER /BW1 Q0 - Q17 2 CQ, /CQ MUX K K /K C C, /C OR K, /K [PD44165364] 17 ADDRESS /R ADDRESS /W 17 REGISTRY & LOGIC K /W MUX ARRAY 72 OUTPUT BUFFER /R MEMORY 36 72 OUTPUT SELECT 72 2 x 144 SENSE AMPS & LOGIC 17 WRITE DRIVER REGISTRY WRITE REGISTER DATA 36 D0 - D35 72 72 OUTPUT REGISTER /BW0 /BW1 /BW2 /BW3 Q0 - Q35 2 CQ, /CQ MUX K /K K C Preliminary Data Sheet M15825EJ1V0DS C, /C OR K, /K 7 PD44165084, 44165184, 44165364 Truth Table Operation WRITE cycle CLK /R /W LH H L D or Q Data in Load address, input write data on two Input data DA(A+0) DA(A+1) DA(A+2) DA(A+3) consecutive K and /K rising edge Input clock K(t+1) /K(t+1) K(t+2) /K(t+2) Load address, read data on two Output data QA(A+0) QA(A+1) QA(A+2) QA(A+3) consecutive C and /C rising edge Output clock /C(t+1) C(t+2) /C(t+2) C(t+3) LH READ cycle NOP (No operation) STANDBY(Clock stopped) L X Data out LH H H D=X or Q=Hi-Z Stopped X X Previous state Remarks 1.

This device contains circuitry that will ensure the outputs will be in High-Z during power-up. 5. Refer to state diagram and timing diagrams for clarification. 6. It is recommended that K = /(/K) = C = /(/C) when clock is stopped. This is not essential but permits most rapid restart by overcoming transmission line charging symmetrically. 7.

The register can be loaded when it is placed between the TDI and TDO pins. The instruction register is automatically preloaded with the IDCODE instruction at power-up whenever the controller is placed in test-logic-reset state. Bypass register The bypass register is a single bit register that can be placed between TDI and TDO. It allows serial test data to be passed through the RAMs TAP to another device in the scan chain with as little delay as possible. ID register The ID Register is a 32 bit register that is loaded with a device and vendor specific 32 bit code when the controller is put in capture-DR state with the IDCODE command loaded in the instruction register. The register is then placed between the TDI and TDO pins when the controller is moved into shift-DR state. Boundary register The boundary register, under the control of the TAP controller, is loaded with the contents of the RAMs I/O ring when the controller is in capture-DR state and then is placed between the TDI and TDO pins when the controller is moved to shift-DR state. Several TAP instructions can be used to activate the boundary register. The Scan Exit Order tables describe which device bump connects to each boundary register location. The first column defines the bit's position in the boundary register. The shift register bit nearest TDO (i.e., first to be shifted out) is defined as bit 1. The second column is the name of the input or I/O at the bump and the third column is the bump number.

It is to be executed whenever the instruction register, whatever length it may be in the device, is loaded with all logic 0s. EXTEST is not implemented in this device. Therefore this device is not 1149.1 compliant. Nevertheless, this RAMs TAP does respond to an all zeros instruction, as follows. With the EXTEST (000) instruction loaded in the instruction register the RAM responds just as it does in response to the SAMPLE instruction, except the RAM output are forced to Hi-Z any time the instruction is loaded. IDCODE The IDCODE instruction causes the ID ROM to be loaded into the ID register when the controller is in capture-DR mode and places the ID register between the TDI and TDO pins in shift-DR mode. The IDCODE instruction is the default instruction loaded in at power up and any time the controller is placed in the test-logic-reset state. BYPASS The BYPASS instruction is loaded in the instruction register when the bypass register is placed between TDI and TDO. This occurs when the TAP controller is moved to the shift-DR state. This allows the board level scan path to be shortened to facilitate testing of other devices in the scan path. SAMPLE SAMPLE is a Standard 1149.1 mandatory public instruction. When the SAMPLE instruction is loaded in the instruction register, moving the TAP controller into the capture-DR state loads the data in the RAMs input and I/O buffers into the boundary scan register. Because the RAM clock(s) are independent from the TAP clock (TCK) it is possible for the TAP to attempt to capture the I/O ring contents while the input buffers are in transition (i.e., in a metastable state). Although allowing the TAP to SAMPLE metastable input will not harm the device, repeatable results cannot be expected. RAM input signals must be stabilized for long enough to meet the TAPs input data capture setup plus hold time (tCS plus tCH). The RAMs clock inputs need not be paused for any other TAP operation except capturing the I/O ring contents into the boundary scan register. Moving the controller to shift-DR state then places the boundary scan register between the TDI and TDO pins. This functionality is not Standard 1149.1 compliant. SAMPLE-Z If the SAMPLE-Z instruction is loaded in the instruction register, all RAM outputs are forced to an inactive drive state (Hi-Z) and the boundary register is connected between TDI and TDO when the TAP controller is moved to the shift-DR state.

To disable the TAP Controller without interfering with normal operation of the device, TCK must be tied to VSS to preclude mid level inputs. TDI and TMS are designed so an undriven input will produce a response identical to the application of a logic 1, and may be left unconnected. But they may also be tied to VDD through a 1k resistor. TDO should be left unconnected. 22 Preliminary Data Sheet M15825EJ1V0DS Test Logic Operation (Instruction Scan) TCK Run-Test/Idle Update-IR Exit1-IR Shift-IR TDI 23 PD44165084, 44165184, 44165364 Output from Instruction Register Output from Instruction Register Exit2-IR Pause-IR Exit1-IR Shift-IR Capture-IR Output Inactive New Instruction IDCODE Instruction Register state Select-IR-Scan Select-DR-Scan Run-Test/Idle TDO Test-Logic-Reset Controller state Preliminary Data Sheet M15825EJ1V0DS TMS 24 Test Logic Operation (Data Scan) TCK Test-Logic-Reset Select-IR-Scan Select-DR-Scan Run-Test/Idle Update-DR Exit1-DR Shift-DR TDI PD44165084, 44165184, 44165364 Output from Instruction Register Output from Instruction Register Exit2-DR Pause-DR Exit1-DR Shift-DR Output Inactive IDCODE Instruction Instruction Register state Capture-DR Select-DR-Scan TDO Run-Test/Idle Controller state Preliminary Data Sheet M15825EJ1V0DS TMS PD44165084, 44165184, 44165364 Package Drawing TBD Preliminary Data Sheet M15825EJ1V0DS 25 PD44165084, 44165184, 44165364 Recommended Soldering Condition Please consult with our sales offices for soldering conditions of these products.

Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.
