Pin Identification

Description
A
Synchronous Address Inputs: These inputs are registered and must meet the setup and hold times around the
rising edge of K for READ cycles and must meet the setup and hold times around the rising edge of /K for
WRITE cycles. Balls 9A, 3A, 10A, and 2A are reserved for the next higher-order address inputs on future
devices. All transactions operate on a burst of two words (one clock period of bus activity). These inputs are
ignored when device is deselected.
D0 to Dxx
Q0 to Qxx
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.
x8 device uses D0 to D7.
x18 device uses D0 to D17.
x36 device uses D0 to D35.
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. This bus operates in response to /R commands. See Pin Configurations for ball site
location of individual signals.
x8 device uses Q0 to Q7.
x18 device uses Q0 to Q17.
x36 device uses Q0 to Q35.
/R
Synchronous Read: When LOW this input causes the address inputs to be registered and a READ cycle to be
initiated. This input must meet setup and hold times around the rising edge of K.
Synchronous Write: When LOW this input causes the address inputs to be registered and a WRITE cycle to be
initiated. This input must meet setup and hold times around the rising edge of K.
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.
/W
/BWx
/NWx
K, /K
C, /C
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. C and /C may be tied HIGH to
force the use of K and /K as the output reference clocks instead of having to provide C and /C clocks. If tied
HIGH, C and /C must remain HIGH and not be toggled during device operation.
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.
Output Impedance Matching Input: This input is used to tune the device outputs to the system data bus
impedance. DQ and CQ output impedance are set to 0.2 x RQ, where RQ is a resistor from this bump to
ground. This pin cannot be connected directly to GND or left unconnected. Also, in this product, there is no
function to minimize the output impedance by connecting ZQ directly to VDDQ.
CQ, /CQ
ZQ
/DLL
DLL Disable: When LOW, this input causes the DLL to be bypassed for stable low frequency operation.
TMS
TDI
IEEE 1149.1 Test Inputs: 1.8V I/O levels. These balls may be left Not Connected if the JTAG function is not
used in the circuit.
TCK
IEEE 1149.1 Clock Input: 1.8V I/O levels. This pin must be tied to VSS if the JTAG function is not used in the
circuit.
TDO
VREF
VDD
IEEE 1149.1 Test Output: 1.8V I/O level.
HSTL Input Reference Voltage: Nominally VDDQ/2. Provides a reference voltage for the input buffers.
Power Supply: 1.8V nominal. See DC Characteristics and Operating Conditions for range.
VDDQ
Power Supply: Isolated Output Buffer Supply. Nominally 1.5V. 1.8V is also permissible. See DC Characteristics
and Operating Conditions for range.
VSS
NC
Power Supply: Ground
No Connect: These signals are internally connected and appear in the JTAG scan chain as the logic level
applied to the ball sites. These signals may be connected to ground to improve package heat dissipation.

Remarks 1. H : High level, L : Low level, × : 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 will ensure the outputs will 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. The device will operate at clock frequencies slower than TKHKH(MAX.).
2. Clock phase jitter is the variance from clock rising edge to the next expected clock rising edge.
3. VDD slew rate must be less than 0.1 V DC per 50 ns for DLL lock retention.
DLL lock time begins once VDD and input clock are stable.
It is recommended that the device is kept inactive during these cycles.
4. 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.
5. 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.

Remarks 1. Q00 refers to output from address A0+0.
Q01 refers to output from the next internal burst address following A0,i.e.,A0+1.
2. Outputs are disable (high impedance) one clock cycle after a NOP.
3. In this example, if address A0=A1, data Q00=D10, Q01=D11.
Write data is forwarded immediately as read results.

Test Mode Select. This is the command input for the TAP controller state machine.
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 determined by the state of the TAP
controller state machine and the instruction that is currently loaded in the TAP instruction.
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.

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.
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.
Bypass register
ID register
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 driver is turned on and the PRELOAD data is driven onto the output pins.
IDCODE
BYPASS
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.
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 / 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 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 kΩ 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
V
IH (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.
