DESCRIPTION
APPLICATION
The M5M5T5636UG is a family of 18M bit synchronous SRAMs
organized as 524288-words by 36-bit. It is designed to eliminate
dead bus cycles when turning the bus around between reads and
writes, or writes and reads. Mitsubishi's SRAMs are fabricated
with high performance, low power CMOS technology, providing
greater reliability. M5M5T5636UG operates on 2.5V power/ 1.8V
I/O supply or a single 2.5V power supply and are 2.5V CMOS
compatible.
High-end networking products that require high bandwidth, such
as switches and routers.
FEATURES
• Fully registered inputs and outputs for pipelined operation
• Fast clock speed: 250, 225, and 200 MHz
• Fast access time: 2.6, 2.8, 3.2 ns
• Single 2.5V -5% and +5% power supply VDD
• Separate VDDQ for 2.5V or 1.8V I/O
• Individual byte write (BWa# - BWd#) controls may be tied
LOW
• Single Read/Write control pin (W#)
• CKE# pin to enable clock and suspend operations
• Internally self-timed, registers outputs eliminate the need to
control G#
• Snooze mode (ZZ) for power down
• Linear or Interleaved Burst Modes
• Three chip enables for simple depth expansion
• JTAG boundary scan support
FUNCTION
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),
Clock Enable (CKE#), Byte Write Enables (BWa#, BWb#, BWc#,
BWd#) and Read/Write (W#). Write operations are controlled by
the four Byte Write Enables (BWa# - BWd#) and Read/Write(W#)
inputs. All writes are conducted with on-chip synchronous selftimed write circuitry.
Asynchronous inputs include Output Enable (G#), Clock (CLK)
and Snooze Enable (ZZ). The HIGH input of ZZ pin puts the
SRAM in the power-down state.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.

PIN FUNCTION
Pin
Function
Name
A0~A18
Synchronous
Address
Inputs
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.
BWa#, BWb#,
BWc#, BWd#
Synchronous
Byte Write
Enables
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.
CLK
Clock Input
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.
E1#
Synchronous
Chip Enable
This active LOW input is used to enable the device and is sampled only when a new external
address is loaded (ADV is LOW).
E2
Synchronous
Chip Enable
This active High input is used to enable the device and is sampled only when a new external
address is loaded (ADV is LOW). This input can be used for memory depth expansion.
E3#
Synchronous
Chip Enable
This active Low input is used to enable the device and is sampled only when a new external
address is loaded (ADV is LOW). This input can be used for memory depth expansion.
G#
Output Enable
This active LOW asynchronous input enable the data I/O output drivers.
ADV
Synchronous
Address
Advance/Load
CKE#
Synchronous
Clock Enable
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.
This active LOW input permits CLK to propagate throughout the device. When HIGH, the device
ignores the CLK input and effectively internally extends the previous CLK cycle. This input must
meet setup and hold times around the rising edge of CLK.
This active HIGH asynchronous input causes the device to enter a low-power standby mode in
which all data in the memory array is retained. When active, all other inputs are ignored. When this
pin is LOW or NC, the SRAM normally operates.
ZZ
Snooze
Enable
W#
Synchronous
Read/Write
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 WRITEs (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.
DQa,DQPa,DQb,DQPb
DQc,DQPc,DQd,DQPd
Synchronous
Data I/O
Byte “a” is DQa , DQPa pins; Byte “b” is DQb, DQPb pins; Byte “c” is DQc, DQPc pins; Byte “d” is
DQd,DQPd pins. Input data must meet setup and hold times around CLK rising edge.
Burst Mode
Control
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.

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. 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
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 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 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 20). The register is then placed between the TDI and TDO pins when the controller is moved into
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. The TAP Controller in this device is not fully 1194.1-compliant because some of the mandatory 1149.1 instructions are
not fully implemented. The TAP on this device may be used to monitor all input and I/O pads. This device will not perform INTEST or
PRELOAD portion of the SAMPLE/PRELOAD command.
When the TAP controller is placed in 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. 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 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. Because the PRELOAD portion of the command is not
implemented in this device, moving the controller to the Update-DR state with the SAMPLE/PRELOAD instruction loaded in the
Instruction Register has the same effect as the Pause-DR command. This functionality is not Standard 1149.1 compliant.

18874368-BIT(524288-WORD BY 36-BIT) NETWORK SRAM
EXTEST
EXTEST is an IEEE 1149.1 mandatory public instruction. It is to be executed whenever the Instruction Register is loaded with all logic 0s.
EXTEST is not implemented in the TAP Controller, and therefore this device is not compliant to the 1149.1 Standard. When the EXTEST
instruction is loaded into the Instruction Register, the device responds as if the SAMPLE/PRELOAD instruction has been loaded. There is
one difference between the two instructions. Unlike the SAMPLE/PRELOAD instruction, EXTEST place the SRAM outputs in a High-Z
state.
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.
