µPD464318AL, 464336AL
Programmable Impedance / Power Up Requirements
An external resistor, RQ, must be connected between the ZQ pin on the SRAM and V SS to allow for the SRAM to
adjust its output driver impedance. The value of RQ must be 5X the value of the intended line impedance driven by
the SRAM. The allowable range of RQ to guarantee impedance matching with a tolerance of 10 % is between 175
ohm and 350 ohm. Periodic readjustment of the output driver impedance is necessary as the impedance is greatly
affected by drifts in supply voltage and temperature. One evaluation occurs every 8 clock cycles and each evaluation
may move the output driver impedance level only one step at a time towards the optimum level. The output driver
has 64 discrete binary weighted steps. The impedance update of the output driver occurs when the SRAM is in Hi-Z.
Write and Deselect operations will synchronously switch the SRAM into and out of Hi-Z, therefore, triggering an
update. Power up requirements for the SRAM are that VDD must be powered before or simultaneously with VDDQ
followed by VREF; inputs should be powered last. The limitation on VDDQ is that it must not exceed VDD by more than
0.4 V during power up. In order to guarantee the optimum internally regulated supply voltage, the SRAM requires 4
µs of power-up time after VDD reaches its operating range. To guarantee optimum output driver impedance after
power up, the SRAM needs 520 clock cycles followed by a single Low-Z to Hi-Z transition at the end of 520 cycles.

Description
TCK
4U
Test Clock Input. All input are captured on the rising edge of TCK and all outputs
propagate from the falling edge of TCK.
TMS
2U
Test Mode Select. This is the command input for the TAP controller state machine.
TDI
3U
Test Data Input. This is the input side of the serial registers placed between TDI and
TDO. The register placed between TDI and TDO is deter-mined by the state of the TAP
controller state machine and the instruction that is currently loaded in the TAP instruction.
TDO
5U
Test Data Output. Output changes in response to the falling edge of TCK. This is the
output side of the serial registers placed between TDI and TDO.
Remark The device does not have TRST (TAP reset). The Test-Logic Reset state is entered while TMS is held high
for five rising edges of TCK. The controller state is also reset on the SRAM POWER-UP.

Scan Register Definition (1)
Register name
Instruction register
Description
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 state. 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.

JTAG Instructions
Instructions
Description
EXTEST
EXTEST is an IEEE 1149.1 mandatory public instruction. 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.

Disabling The Test Access Port
It is possible to use this device without utilizing the TAP. 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 1 k resistor.
TDO should be left unconnected.

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. 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.
