CY7C1328A/GVT71256F18

CY7C1348A/GVT71128F36

PRELIMINARY

128K x 36/256K x 18

Synchronous-Pipelined Cache RAM

and a 2-bit counter for internal burst operation. All synchro-

nous inputs are gated by registers controlled by a posi-

tive-edge-triggered Clock Input (CLK). The synchronous in-

puts include all addresses, all data inputs, address-pipelining

Chip Enable (CE), depth-expansion Chip Enables (CE2 and

CE2), Burst Control inputs (ADSC, ADSP, and ADV), Write En-

ables (BW1, BW2, BW3, BW4, and BWE), and Global Write

Features

• Fast access times: 3.5, 3.8, and 4.0 ns

• Fast clock speed: 166, 150, 133, and 117 MHz

• Provide high performance 3-1-1-1 access rate

• Fast OE access times: 3.5 ns and 3.8 ns

• Optimal for performance (double cycle chip deselect,

depth expansion without wait state)

• 3.3V –5% and +10% core power supply

• 2.5V or 3.3V I/O supply

• 5V tolerant inputs except I/Os

(GW).

Asynchronous inputs include the Output Enable (OE) and

Burst Mode Control (MODE). The data outputs (Q), enabled

by OE, are also asynchronous.

Addresses and chip enables are registered with either Ad-

dress Status Processor (ADSP) or Address Status Controller

(ADSC) input pins. Subsequent burst addresses can be inter-

nally generated as controlled by the Burst Advance pin (ADV).

• Clamp diodes to V

• Common data inputs and data outputs

• Byte Write Enable and Global Write control

at all inputs and outputs

SSQ

• Three chip enables for depth expansion and address

pipeline

• Address, data and control registers

• Internally self-timed Write Cycle

• Burst control pins (interleaved or linear burst se-

quence)

• Automatic power-down for portable applications

• High-density, high-speed packages

Address, data inputs, and write controls are registered on-chip

to initiate self-timed WRITE cycle. WRITE cycles can be one

to four bytes wide as controlled by the write control inputs.

Individual byte write allows individual byte to be written. BW1

controls DQ1–DQ8 and DQP1. BW2 controls DQ9–DQ16 and

DQP2. BW3 controls DQ17–DQ24 and DQP3. BW4 controls

DQ25–DQ32 and DQP4. BW1, BW2, BW3, and BW4 can be

active only with BWE being LOW. GW being LOW causes all

bytes to be written. WRITE pass-through capability allows writ-

ten data available at the output for the immediately next READ

cycle. This device also incorporates pipelined enable circuit for

easy depth expansion without penalizing system performance.

Functional Description

The Cypress Synchronous Burst SRAM family employs

high-speed, low-power CMOS designs using advanced tri-

ple-layer polysilicon, double-layer metal technology. Each

memory cell consists of four transistors and two high-valued

resistors.

The CY7C1348A/GVT71128F36/CY7C1328A/GVT71256F18

operates from a +3.3V core power supply and all outputs op-

erate on a +2.5V supply. All inputs and outputs are JEDEC

standard JESD8-5 compatible. The device is ideally suited for

486, Pentium®, 680x0, and PowerPC™ systems and for sys-

tems that benefit from a wide synchronous data bus.

The

CY7C1348A/GVT71128F36

and

CY7C1328A/

GVT71256F18 SRAM integrate 262,144x18 and 131,072x36

SRAM cells with advanced synchronous peripheral circuitry
