M5M5Y5672TG - 25,22,20
18874368-BIT(262144-WORD BY 72-BIT) NETWORK SRAM Synchronous circuitry allows for precise cycle control triggered by a positive edge clock transition. Synchronous signals include : all Addresses, all Data Inputs, all Chip Enables (E1#, E2, E3), Address Advance/Load (ADV), Byte Write Enables (BWa#, BWb#, BWc#, BWd#, BWe#, BWf#, BWg#, BWh#), Echo Clock outputs (CQ1, CQ1#, CQ2, CQ2#) and Read/Write (W#). Write operations are controlled by the eight Byte Write Enables (BWa# - BWh#) and Read/Write(W#) inputs. All writes are conducted with on-chip synchronous self-timed write circuitry. The Echo Clocks are delayed copies of the RAM clock, CLK. Echo Clocks are designed to track changes in output driver delays due to variance in die temperature and supply voltage. The ZQ pin supplied with selectable impedance drivers, allows selection between nominal drive strength (ZQ LOW) for multi-drop bus application and low drive strength (ZQ floating or HIGH) point-to-point applications. The sense of two User-Programmable Chip Enable inputs (E2, E3), whether they function as active LOW or active HIGH inputs, is determined by the state of the programming inputs, EP2 and EP3. The Linear Burst order (LBO#) is DC operated pin. LBO# pin will allow the choice of either an interleaved burst, or a linear burst. All read, write and deselect cycles are initiated by the ADV Low input. Subsequent burst address can be internally generated as controlled by the ADV HIGH input.

Function
These inputs are registered and must meet the setup and hold times around the rising edge of CLK. A0 and A1 are the two least significant bits (LSB) of the address field and set the internal burst counter if burst is desired. These active LOW inputs allow individual bytes to be written when a WRITE cycle is active and must meet the setup and hold times around the rising edge of CLK. BYTE WRITEs need to be asserted on the same cycle as the address. BWs are associated with addresses and apply to subsequent data. BWa# controls DQa, DQPa pins; BWb# controls DQb, DQPb pins; BWc# controls DQc, DQPc pins; BWd# controls DQd, DQPd pins; BWe# controls DQe, DQPe pins; BWf# controls DQf, DQPf pins; BWg# controls DQg, DQPg pins; BWh# controls DQh, DQPh pins. This signal registers the address, data, chip enables, byte write enables and burst control inputs on its rising edge. All synchronous inputs must meet setup and hold times around the clock's rising edge. This active LOW input is used to enable the device and is sampled only when a new external address is loaded (ADV is LOW). These pins are user-programmable chip enable inputs. The sense of the inputs, whether they function as active LOW or HIGH inputs, is determined by the state of the programming inputs, EP2 and EP3. These pins determine the sense of the user-programmable chip enable inputs, whether they function as active LOW or active HIGH inputs. When HIGH, this input is used to advance the internal burst counter, controlling burst access after the external address is loaded. When HIGH, W# is ignored. A LOW on this pin permits a new address to be loaded at CLK rising edge. The Echo Clocks are delayed copies of the main RAM clock, CLK. This pin allows selection between RAM nominal drive strength (ZQ low) for multi-drop bus applications and low drive strength (ZQ floating or high) point-to-point application. This active input determines the cycle type when ADV is LOW. This is the only means for determining READs and WRITEs. READ cycles may not be converted into W RITEs (and vice versa) other than by loading a new address. A LOW on the pin permits BYTE WRITE operations and must meet the setup and hold times around the rising edge of CLK. Full bus width WRITEs occur if all byte write enables are LOW. Byte "a" is DQa , DQPa pins; Byte "b" is DQb, DQPb pins; Byte "c" is DQc, DQPc pins; Byte "d" is DQd,DQPd pins; Byte "e" is DQe, DQPe pins; Byte "f" is DQf, DQPf pins; Byte "g" is DQg, DQPg pins; Byte "h" is DQh, DQPh pins. Input data must meet setup and hold times around CLK rising edge. This DC operated pin allows the choice of either an interleaved burst or a linear burst. If this pin is HIGH or NC, an interleaved burst occurs. When this pin is LOW, a linear burst occurs, and input leak current to this pin. Core Power Supply Ground I/O buffer Power supply

Read Operation Pipelined Read
Read operation is initiated when the following conditions are satisfied at the rising edge of clock: All three chip enables (E1#, E2 and E3) are active, the write enable input signal (W#) is deasserted high, and ADV is asserted low. The address presented to the address inputs is latched into the address register and presented to the memory core and control logic. The control logic determines that a read access is in progress and allows the requested data to propagate to the input of the output register. At the next rising edge of clock the read data is allowed to propagate through the output register and onto the output pins.

Write Operation Double Late Write
Write operation occurs when the following conditions are satisfied at the rising edge of clock: All three chip enables (E1#, E2 and E3) are active and the write enable input signal (W#) is asserted low. Double Late Write means that Data In is required on the third rising edge of clock. It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads.

Special Function Burst Cycles
The SRAM provides an on-chip burst address generator that can be utilized, if desired, to further simplify burst read or write implementations. The ADV control pin, when driven high, commands the SRAM to advance the internal address counter and use the counter generated address to read or write the SRAM. The starting address for the first cycle in a burst cycle series is loaded into the SRAM by driving the ADV pin low, into Load mode. Burst Read CLK E1# ADV W# BWx# ADD DQ CQ

Echo Clock
The SRAM features Echo Clocks, CQ1,CQ2, CQ1#, and CQ2# that track the performance of the output drivers. The Echo Clocks are delayed copies of the main RAM clock, CLK. Echo Clocks are designed to track changes in output driver delays due to variance in die temperature and supply voltage. The Echo Clocks are designed to fire with the rest of the data output drivers. The SRAM provide both in-phase, or true, Echo Clock outputs (CQ1 and CQ2) and inverted Echo Clock outputs (CQ1# and CQ2#). It should be noted that deselection of the SRAM via E2 and E3 also deselects the Echo Clock output drivers. The deselection of Echo Clock drivers is always pipelined to the same degree as output data. Deselection of the SRAM via E1# does not deactivate the Echo Clocks.
Programmable Enable
The SRAM features two user programmable chip enable inputs, E2 and E3. The sense of the inputs, whether they function as active low or active high inputs, is determined by the state of the programming inputs, EP2 and EP3. For example, if EP2 is held at HIGH, E2 functions as an active high enable. If EP2 is held to LOW, E2 functions as an active low chip enable input. Programmability of E2 and E3 allows for banks of depth expansion to be accomplished with no additional logic. By programming the enable inputs of four SRAMs in binary sequence (00,01,10,11) and driving the enable inputs with two address inputs, four SRAMs can be made to look like one larger SRAM to the system.

Note10. E1# does not deselect the Echo Clock Outputs. Echo Clock outputs are synchronously deselected by E2 or E3 being sampled false.
In some applications it may be appropriate to pause between banks; to deselect both SRAMs with E1# before resuming read operations. An E1# deselect at a bank switch will allow at least one clock to be issued from the new bank before the first read cycle in the bank. Although the following drawing illustrates a E1# read pause upon switching from Bank 1 to Bank 2, a write to Bank 2 would have the same effect, causing the SRAM in Bank 2 to issue at least one clock before it is needed.
Output Driver Impedance Control
The ZQ pin of SRAMs supplied with selectable impedance drivers, allows selection between SRAM nominal drive strength (ZQ low) for multi-drop bus applications and low drive strength (ZQ floating or high) point-to-point applications.

JTAG PORT OPERATION Overview
The JTAG Port on this SRAM operates in a manner consistent with IEEE Standard 1149.1-1990, a serial boundary scan interface standard (commonly referred to as JTAG), but dose not implement all of the function required for 1149.1 compliance. Unlike JTAG implementations that have been common among SRAM vendors for the last several years, this implementation dose offer a form of EXTEST, known as Clock Assisted EXTEST, reducing or eliminating the "hand coding" that has been required to overcome the test program compiler errors caused by previous non-compliant implementation. The JTAG Port interfaces with conventional CMOS logic level signaling.
Disabling the JTAG port
It is possible to use this device without utilizing the JTAG port. The port is reset at power-up and will remain inactive unless clocked. To assure normal operation of the SRAM with the JTAG Port unused, the TCK, TDI and TMS pins may be left floating or tied to High. The TDO pin should be left unconnected.
JTAG Pin Description
Test Clock (TCK) The TCK input is clock for all TAP events. All inputs are captured on the rising edge of TCK and the Test Data Out (TDO) propagates from the falling edge of TCK. Test Mode Select (TMS) The TMS input is sampled on the rising edge of TCK. This is the command input for the TAP Controller state machine. An undriven TMS input will produce the same result as a logic one input level. Test Data In (TDI) The TDI input is sampled on the rising edge of TCK. This is the input side of the serial registers placed between the TDI and TDO pins. the register placed between the TDI and TDO pins is determined by the state of the TAP Controller state machine and the instruction that is currently loaded in the TAP Instruction Resister (refer to the TAP Controller State Diagram). An undriven TDI Input will produce the same result as a logic one input level. Test Data Out (TDO) The TDO output is active depending on the state of the TAP Controller state machine. Output changes in response to the falling edge of TCK. This is the output side of the serial registers placed between the TDI and TDO pins. Note: This device dose not have a TRST (TAP Reset) pin. TRST is optional in IEEE 1149.1. The Test-Logic-Reset state is entered while TMS is held high for five rising edges of TCK. The TAP Controller is also reset automatically at power-up.
JTAG Port Registers
Overview The various JTAG registers, referred to as Test Access Port or TAP Registers, are selected (one at a time) via the sequence of 1s and 0s applied to TMS as TCK is strobed. Each of TAP Registers are serial shift registers that capture serial input data on the rising edge of TCK and push serial data out on the next falling edge of TCK. When a register is selected, it is placed between the TDI and TDO pins. Instruction Register The Instruction Register holds the instructions that are executed by the TAP Controller when it is moved into the Run-Test/Idle, or the 19

M5M5Y5672TG - 25,22,20
18874368-BIT(262144-WORD BY 72-BIT) NETWORK SRAM various data register states. Instructions are 3 bits long. The Instruction Resister can be loaded when it is placed between the TDI and TDO pins. The Instruction Resister is automatically preloaded with the IDCODE instruction at power-up or whenever the controller is placed in the Test-Logic-Reset state. Bypass Register The Bypass resister is a single-bit register that can be placed between the TDI and TDO pins. It allows serial test data to be passed through the SRAM's JTAG Port to another device in the scan chain with as little delay as possible. Boundary Scan Register The Boundary Scan Register is a collection of flip flops that can be preset by the logic level found on the SRAM's input or I/O pins. The flip flops are then daisy chained together so the levels found can be shifted serially out of the JTAG Port's TDO pins. The Boundary Scan Register also includes a number of place holder flip flops (always set to a logic 1). The relationship between the device pins and the bits in the Boundary Scan Register is described in the Scan Order Table following. The Boundary Scan Register, under the control of the TAP Controller, is loaded with the contents of the SRAM's I/O ring when the controller is in the Capture-RD state and then is placed between the TDI and TDO pins when the controller is moved to the Shift-DR state. SAMPLE-Z, SAMPLE/PRELOAD and EXTEST instruction can be used to activate the Boundary Scan Register. Identification (ID) Register The ID register is a 32-bit register that is loaded with a device and vender specific 32-bit code when the controllers put in the Capture-DR state with the IDCODE Instruction loaded in the Instruction Register. The code is loaded from 32-bit on-chip ROM. It describes various attributes of the SRAM (see page 25). The register is then placed between the TDI and TDO pins when the controller is moved into the Shift-DR state. Bit 0 in the register is the LSB and the first to reach the TDO pin when shifting begins.
TAP Controller Instruction Set
Overview There are two classes of instructions defined in the Standard 1149.1-1990; standard (Public) instructions, and device specific (Private) instructions. Some Public instructions are mandatory for 1149.1 compliance. Optional Public instructions must be implemented in prescribed ways. Although the TAP Controller in this device follows the 1149.1 conventions, it is not 1194.1-compliant because one of the mandatory instructions, EXTEST, is uniquely implemented. The TAP on this device may be used to monitor all input and I/O pads. This device will not perform INTEST but can perform the preload portion of the SAMPLE/PRELOAD command. When the TAP controller is placed in the Capture-IR state, the two least significant bits of the instruction register are loaded with 01. When the TAP controller is moved to the Shift-IR state, the Instruction Register is placed between the TDI and TDO pins. In this state the desired instruction is serially loaded through the TDI input (while the previous contents are shifted out at the TDO output). For all instructions, the TAP executes newly loaded instructions only when the controller is moved to the Update-IR state. The TAP Instruction Set for this device is listed in the following table. Instruction Descriptions BYPASS When the BYPASS instruction is loaded in the Instruction Register, the Bypass Register is placed between the TDI and TDO pins. 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/PRELOAD SAMPLE/PRELOAD is a Standard1149.1 mandatory public instruction. When the SAMPLE/PRELOAD instruction is loaded in the Instruction Register, moving the TAP Controller into the Capture-DR state loads the data in the SRAM's input and I/O buffers into the Boundary Scan Register. Some Boundary Scan Register locations are not associated with an input or I/O pin, and are loaded with the default state identified in the BSDL file. Because the SRAM clock is 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 20

M5M5Y5672TG - 25,22,20
18874368-BIT(262144-WORD BY 72-BIT) NETWORK SRAM sample metastable inputs will not harm the device, repeatable results cannot be expected. SRAM input signals must be stabilized for long enough to meet the TAP's input data capture set-up plus hold time (tTS plus tTH). The SRAM's 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 the Shift-DR state then places the Boundary Scan Register between the TDI and TDO pins. EXTEST-A EXTEST is an IEEE 1149.1 mandatory public instruction. It is to be executed whenever the Instruction Register is loaded with all logic 0s. The EXTEST command dose not block or override the SRAM's input pins; therefore, the SRAM's internal state is still determined by its input pins. Typically, the Boundary Scan Register is loaded with the desired pattern with the SAMPLE/PRELOAD command. Then the EXTEST command is used to output the Boundary Scan Register's contents, in parallel, on the SRAM's data output drivers on the falling edge of TCK when the controller is in the Update-IR state. Alternately, the Boundary Scan Register may loaded in parallel using the EXTEST command. When the EXTEST instruction is selected, the state of all SRAM's input and I/O pins, as well as the default values at Scan Register locations not associated with a pin, are transferred in parallel into the Boundary Scan Register on the rising edge of TCK in the Capture-DR state, the SRAM's output pins drive out the value of the Boundary Scan Register location with which each output pin is associated. The EXTEST implementation in this device dose not, without further user intervention, actually move the contents of the scan chain onto the SRAM's output pins. Therefore this device is not strictly 1149.1-compliant. To push data from the Boundary Scan Registers, in parallel, out onto the SRAM's I/O and output pins, the SRAM's main clock (CK) must be pulsed. A single CK transition is sufficient to transfer the data, but more transitions will do no harm. IDCODE The IDCODE instruction cause the ID ROM to be loaded into the ID register when the controller is in the Capture-DR state and places the ID Register between the TDI and TDO pins in the Shift-DR state. 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. SAMPLE-Z If the SAMPLE-Z instruction is loaded in the Instruction Register, all SRAM outputs are forced to an inactive drive state (High-Z) and the Boundary Scan Register is placed between the TDI and TDO pins when the TAP Controller is moved to the Shift-DR state. RFU These instructions are reserved for future use. Do not use these instructions.
