Pin Identification (1/2)

Symbol Description

A 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).

D0 to Dxx 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.

x9 device uses D0 to D8.

x18 device uses D0 to D17.

x36 device uses D0 to D35.

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.

K, K# 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.

C, C# 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#)

Symbol 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.

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. V

DD 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.

TKC reset

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.

JTAG Specification

These products support a limited set of JTAG functions as in IEEE standard 1149.1.

Test Access Port (TAP) Pins

Pin name Pin assignments Description

TCK 2R Test Clock Input. All input are captured on the rising edge of TCK and all outputs

propagate from the falling edge of TCK.

TMS 10R Test Mode Select. This is the command input for the TAP controller state machine.

TDI 11R 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.

TDO 1R Test Data Output. This is the output side of the serial registers placed between TDI and

TDO. Output changes in response to the falling edge of TCK.

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 TAP controller state is also reset on the SRAM POWER-UP.

Scan Register Definition (1)

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 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 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 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.

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 V

(MAX) and V

(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 V

(MAX) and

(MIN).

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 V

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.

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 dr y, 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.

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.

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.

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.
