Description
The μPD44164085A is a 2,097,152-word by 8-bit, the μPD44164095A is a 2,097,152-word by 9-bit, the μPD44164185A
is a 1,048,576-word by 18-bit and the μPD44164365A is a 524,288-word by 36-bit synchronous double data rate static
RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.
The μPD44164085A, μPD44164095A, μPD44164185A and μPD44164365A integrate unique synchronous peripheral
circuitry and a burst counter. All input registers controlled by an input clock pair (K and K#) are latched on the positive
edge of K and K#.
These products are suitable for application which require synchronous operation, high speed, low voltage, high density
and wide bit configuration.
These products are packaged in 165-pin PLASTIC BGA.
Features
• 1.8 ± 0.1 V power supply
• 165-pin PLASTIC BGA package (13 x 15)
• HSTL interface
• PLL circuitry for wide output data valid window and future frequency scaling
• Separate independent read and write data ports
• DDR read or write operation initiated each cycle
• Pipelined double data rate operation
• Separate data input/output bus
• Two-tick burst for low DDR transaction size
• Two input clocks (K and K#) for precise DDR timing at clock rising edges only
• Two output clocks (C and C#) for precise flight time and clock skew matching-clock
and data delivered together to receiving device
• Internally self-timed write control
• Clock-stop capability. Normal operation is restored in 1,024 cycles after clock is resumed.
• User programmable impedance output

Synchronous Address Inputs: These inputs are registered and must meet the setup and hold times around the
rising edge of K. All transactions operate on a burst of two words (one clock period of bus activity). These
inputs are ignored when device is deselected, i.e., NOP (LD# = HIGH).
Synchronous Data Inputs: Input data must meet setup and hold times around the rising edges of K and K#
during WRITE operations. See Pin Configurations for ball site location of individual signals.

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. Data is output in synchronization with C and C# (or K and K#), depending on the
LD# and R, W# command. See Pin Configurations for ball site location of individual signals.
x8 device uses Q0 to Q7.
x9 device uses Q0 to Q8.
x18 device uses Q0 to Q17.
x36 device uses Q0 to Q35.
LD#
Synchronous Load: This input is brought LOW when a bus cycle sequence is to be defined. This definition
includes address and read/write direction. All transactions operate on a burst of 2 data (one clock period of bus
activity).
R, W#
Synchronous Read/Write Input: When LD# is LOW, this input designates the access type (READ when R, W#
is HIGH, WRITE when R, W# is LOW) for the loaded address. R, W# must meet the setup and hold times
around the rising edge of K.
BWx#
NWx#
Synchronous Byte Writes (Nibble Writes on x8): When LOW these inputs cause their respective byte or nibble
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
Configurations for signal to data relationships.
x8 device uses NW0#, NW1#.
x9 device uses BW0#.
x18 device uses BW0#, BW1#.
x36 device uses BW0# to BW3#.
See Byte Write Operation for relation between BWx#, NWx# and Dxx.
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 output data. The rising edge of C is used as the output
reference for second output data. Ideally, #C is 180 degrees out of phase with C. When use of K and K# as the
reference instead of C and C#, then fixed C and C# to HIGH. Operation cannot be guaranteed unless C and
C# are fixed to HIGH (i.e. toggle of C and C#)

Description
CQ, CQ#
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. If C and C# are stopped (if K and K# are stopped in the single clock mode), CQ and CQ# will also
stop.
<R>
<R>
ZQ
Output Impedance Matching Input: This input is used to tune the device outputs to the system data bus
impedance. Q, CQ and CQ# output impedance are set to 0.2 x RQ, where RQ is a resistor from this bump to
ground. The output impedance can be minimized by directly connect ZQ to VDDQ. This pin cannot be
connected directly to GND or left unconnected. The output impedance is adjusted every 1,024 cycles upon
power-up to account for drifts in supply voltage and temperature. After replacement for a resistor, the new
output impedance is reset by implementing power-on sequence.
DLL#
DLL/PLL Disable: When debugging the system or board, the operation can be performed at a clock frequency
slower than TKHKH (MAX.) without the DLL circuit being used, if DLL# = LOW. The AC/DC characteristics
cannot be guaranteed. For normal operation, DLL# must be HIGH and it can be connected to VDDQ through a
10 kΩ or less resistor.

Remarks 1. H : HIGH, L : LOW, × : don’t care, ↑ : rising edge.
2. Data inputs are registered at K and K# rising edges. Data outputs are delivered at C and C# rising edges
except if C and C# are HIGH then Data outputs are delivered at K and K# rising edges.
3. All control inputs in the truth table must meet setup/hold times around the rising edge (LOW to HIGH) of
K. All control inputs are registered during the rising edge of K.
4. This device contains circuitry that ensure the outputs to be in high impedance 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.

Notes 1. When debugging the system or board, these products can operate at a clock frequency slower than TKHKH
(MAX.) without the DLL/PLL circuit being used, if DLL# = LOW. Read latency (RL) is changed to 1.5 clock in
this operation. The AC/DC characteristics cannot be guaranteed, however.
2. Clock phase jitter is the variance from clock rising edge to the next expected clock rising edge. TKC var
(MAX.) indicates a peak-to-peak value.
3. VDD slew rate must be less than 0.1 V DC per 50 ns for DLL/PLL lock retention.
DLL/PLL lock time begins once VDD and input clock are stable.
It is recommended that the device is kept NOP (LD# = HIGH) during these cycles.
4. K input is monitored for this operation. See below for the timing.

5. Echo clock is very tightly controlled to data valid / data hold. By design, there is a 0.1 ns variation from
echo clock to data. The data sheet parameters reflect tester guardbands and test setup variations.
6. This is a synchronous device. All addresses, data and control lines must meet the specified setup
and hold times for all latching clock edges.
Remarks 1. This parameter is sampled.
2. Test conditions as specified with the output loading as shown in AC Test Conditions
unless otherwise noted.
3. Control input signals may not be operated with pulse widths less than TKHKL (MIN.).
4. If C, C# are tied HIGH, K, K# become the references for C, C# timing parameters.
5. VDDQ is 1.5 V DC.

Scan Register Definition (1)
Register name
Description
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 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
ID 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.
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 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
EXTEST
Description
The EXTEST instruction allows circuitry external to the component package to be tested. Boundary-
scan register cells at output pins are used to apply test vectors, while those at input pins capture test
results. Typically, the first test vector to be applied using the EXTEST instruction will be shifted into the
boundary scan register using the PRELOAD instruction. Thus, during the update-IR state of EXTEST,
the output drive is turned on and the PRELOAD data is driven onto the output pins.
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
When the BYPASS instruction is loaded in the instruction register, 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 / PRELOAD
SAMPLE / PRELOAD is a Standard 1149.1 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 RAMs input and Q pins 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.
SAMPLE-Z
If the SAMPLE-Z instruction is loaded in the instruction register, all RAM Q pins are forced to an
inactive 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 may be left open but fix
them to VDD via a resistor of about 1 kΩ when the TAP controller is not used. TDO should be left unconnected also
when the TAP controller is not used.

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).
HANDLING OF UNUSED INPUT PINS
2
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.
5
POWER ON/OFF SEQUENCE
In the case of a device that uses different power supplies for the internal operation and external
interface, as a rule, switch on the external power supply after switching on the internal power supply.
When switching the power supply off, as a rule, switch off the external power supply and then the
internal power supply. Use of the reverse power on/off sequences may result in the application of an
overvoltage to the internal elements of the device, causing malfunction and degradation of internal
elements due to the passage of an abnormal current.
The correct power on/off sequence must be judged separately for each device and according to related
specifications governing the device.
6
INPUT OF SIGNAL DURING POWER OFF STATE
Do not input signals or an I/O pull-up power supply while the device is not powered. The current
injection that results from input of such a signal or I/O pull-up power supply may cause malfunction and
the abnormal current that passes in the device at this time may cause degradation of internal elements.
Input of signals during the power off state must be judged separately for each device and according to
related specifications governing the device.
