PRELIMINARY

CY7C1352B

256K x18 Pipelined SRAM with NoBL™ Architecture

• Low standby power

Features

Functional Description

• Pin compatible and functionally equivalent to ZBT™

devices MCM63Z818 and MT55L256L18P

The CY7C1352B is a 3.3V 256K by 18 synchronous-pipelined

Burst SRAM designed specifically to support unlimited true

back-to-back Read/Write operations without the insertion of

wait states. The CY7C1352B is equipped with the advanced

No Bus Latency™ (NoBL™) logic required to enable consec-

utive Read/Write operations with data being transferred on ev-

ery clock cycle. This feature dramatically improves the

throughput of the SRAM, especially in systems that require

frequent Read/Write transitions. The CY7C1352B is pin/func-

tionally compatible to ZBT SRAMs MCM63Z819 and

MT55L256L18P.

• Supports 166-MHz bus operations with zero wait states

— Data is transferred on every clock

• Internally self-timed output buffer control to eliminate

the need to use OE

• Fully registered (inputs and outputs) for pipelined

operation

• Byte Write Capability

• 256K x 18 common I/O architecture

• Single 3.3V power supply

All synchronous inputs pass through input registers controlled

by the rising edge of the clock. All data outputs pass through

output registers controlled by the rising edge of the clock. The

clock input is qualified by the Clock Enable (CEN) signal, which

when deasserted suspends operation and extends the previ-

ous clock cycle. Maximum access delay from the clock rise is

3.5 ns (166-MHz device).

• Fast clock-to-output times

— 3.5 ns (for 166-MHz device)

— 3.8 ns (for 150-MHz device)

— 4.0 ns (for 143-MHz device)

— 4.2 ns (for 133-MHz device)

— 5.0 ns (for 100-MHz device)

Write operations are controlled by the four Byte Write Select

— 7.0 ns (for 80-MHz device)

(BWS

) and a Write Enable (WE) input. All writes are con-

[1:0]

• Clock Enable (CEN) pin to suspend operation

• Synchronous self-timed writes

• Asynchronous output enable

• JEDEC-standard 100-pin TQFP package

• Burst Capability—linear or interleaved burst order

ducted with on-chip synchronous self-timed write circuitry.

Three synchronous Chip Enables (CE , CE , CE ) and an

asynchronous Output Enable (OE) provide for easy bank se-

lection and output three-state control. In order to avoid bus

contention, the output drivers are synchronously three-stated

during the data portion of a write sequence.
