µPD44323362
Programmable Impedance / Power Up Requirements
An external resistor, RQ, must be connected between the ZQ pin on the SRAM and VSS 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 15% 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. The impedance update of the output driver occurs only when the
SRAM is in high impedance. Write and Deselect operations will synchronously switch the SRAM into and out of high
impedance, 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 during power up. In order to guarantee the optimum internally regulated supply voltage, the
SRAM requires 4096 clock cycles of power-up time after VDD reaches its operating range. And CID impedance is not
updated during the clock stopped.
Sleep Mode
Sleep Mode is enabled by switching asynchronous signal ZZ High. When the SRAM is in Sleep Mode, the output
will go to a high impedance state and the SRAM will draw standby current. SRAM data will be preserved and a
recovery time (tZZR) is required before the SRAM resumes normal operation. And CID impedance is not updated
during the sleep mode.

Scan Register Definition (1)
Register name
Description
The instruction register holds the instructions that are executed by the TAP controller when it is moved
Instruction register
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.
The bypass register is a single bit register that can be placed between TDI and TDO. It allows serial test
Bypass register
data to be passed through the RAMs TAP to another device in the scan chain with as little delay as
possible.
The ID Register is a 32 bit register that is loaded with a device and vendor specific 32 bit code when the
ID register
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.
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
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

Description
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.
EXTEST
Therefore this device is not 1149.1 compliant.
respond to an all zeros instruction, as follows.
Nevertheless, this RAMs TAP does
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 high impedance any time the instruction is loaded.
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
IDCODE instruction is the default instruction loaded in at power up and any time the controller is placed in
the test-logic-reset state.
The BYPASS instruction is loaded in the instruction register when the bypass register is placed between
BYPASS
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 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
SAMPLE
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.
If the SAMPLE-Z instruction is loaded in the instruction register, all RAM outputs are forced to an inactive
SAMPLE-Z
drive state (high impedance) 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 1k Ω resistor.
TDO should be left unconnected.

NOTES FOR CMOS DEVICES
1
VOLTAGE APPLICATION WAVEFORM AT INPUT PIN
Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the
CMOS device stays in the area between VIL (MAX) and VIH (MIN) due to noise, etc., the device may
malfunction. Take care to prevent chattering noise from entering the device when the input level is fixed,
and also in the transition period when the input level passes through the area between VIL (MAX) and
VIH (MIN).
2
HANDLING OF UNUSED INPUT PINS
Unconnected CMOS device inputs can be cause of malfunction. If an input pin is unconnected, it is
possible that an internal input level may be generated due to noise, etc., causing malfunction. CMOS
devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed
high or low by using pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND
via a resistor if there is a possibility that it will be an output pin. All handling related to unused pins must
be judged separately for each device and according to related specifications governing the device.
3
PRECAUTION AGAINST ESD
A 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 when it has occurred.
Environmental control must be
adequate. When it is dry, a humidifier should be used. It is recommended to avoid using insulators that
easily build up 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
benches and floors should be grounded.
The operator should be grounded using a wrist strap.
Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for
PW boards with mounted semiconductor devices.
4
STATUS BEFORE INITIALIZATION
Power-on does not necessarily define the initial status of a MOS device. Immediately after the power
source is turned ON, devices with reset functions have not yet been initialized. Hence, power-on does
not guarantee output pin levels, I/O settings or contents of registers. A device is not initialized until the
reset signal is received. A reset operation must be executed immediately after power-on for devices
with reset functions.
