Description

The IDT71V632 is a 3.3V high-speed SRAM organized as 64K x 32

Pin Description Summary

Pentium processor is a trademark of Intel Corp.

PowerPC is a trademark of International Business Machines, Inc.

64K x 32

3.3V Synchronous SRAM

Pipelined Outputs

Burst Counter, Single Cycle Deselect

IDT71V632/Z

with full support of the Pentium™ and PowerPC™ processor interfaces.

The pipelined burst architecture provides cost-effective 3-1-1-1 second-

ary cache performance for processors up to 117MHz.

The IDT71V632 SRAM contains write, data, address, and control

registers. Internal logic allows the SRAM to generate a self-timed write

based upon a decision which can be left until the extreme end of the write

cycle.

The burst mode feature offers the highest level of performance to the

system designer, as the IDT71V632 can provide four cycles of data for

a single address presented to the SRAM. An internal burst address counter

accepts the first cycle address from the processor, initiating the access

sequence. The first cycle of output data will be pipelined for one cycle before

it is available on the next rising clock edge. If burst mode operation is

selected (ADV=LOW), the subsequent three cycles of output data will be

available to the user on the next three rising clock edges. The order of these

three addresses will be defined by the internal burst counter and the LBO

input pin.

The IDT71V632 SRAM utilizes IDT's high-performance, high-volume

3.3V CMOS process, and is packaged in a JEDEC Standard 14mm x

20mm 100-pin thin plastic quad flatpack (TQFP) for optimum board density

in both desktop and notebook applications.

1. The LBO pin will be internally pulled to VDD if it is not actively driven in the application and the ZZ pin will be internally pulled to VSS if not actively driven.

NOTES:

1. All values are maximum guaranteed values.

2. At f = fMAX, inputs are cycling at the maximum frequency of read cycles of 1/tCYC while ADSC = LOW; f=0 means no input lines are changing.

NOTES:

1. Measured as HIGH above 2.0V and LOW below 0.8V.

2. Transition is measured ±200mV from steady-state.

3. Device must be deselected when powered-up from sleep mode.

4. tCFG is the minimum time required to configure the device based on the LBO input. LBO is a static input and must not change during normal operation.

5. The 71V632SA4 speed grade corresponds to a tCD of 4.5ns.

6. 0°C to +70°C temperature range only.

2. ZZ input is LOW and LBO is Don’t Care for this cycle.

3. CS0 timing transitions are identical but inverted to the CE and CS1 signals. For example, when CE and CS1 are LOW on this waveform, CS0 is HIGH.

Timing Wa v ef orm of Write Cyc le No . 1 — GW Controlled(1,2,3)

NOTES:

1. ZZ input is LOW, BWE is HIGH, and LBO is Don’t Care for this cycle.

2 . O4(Aw) represents the final output data in the burst sequence of the base address Aw. I1(Ax) represents the first input from the external address Ax. I1(Ay) represents the first input from the external address

Ay; I2(Ay) represents the next input data in the burst sequence of the base address Ay, etc. where A0 and A1 are advancing for the four word burst in the sequence defined by the state of the LBO input.

In the case of input I2(Ay) this data is valid for two cycles because ADV is high and has suspended the burst.

3. CS0 timing transitions are identical but inverted to the CE and CS1 signals. For example, when CE and CS1 are LOW on this waveform, CS0 is HIGH.
