PRELIMINARY

256Kx36/512Kx18 Pipelined SRAM with NoBL™ Architecture

spectively. They are designed specifically to support unlimited

Features

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

of wait states. The CY7C1354V25/CY7C1356V25 is equipped

with the advanced No Bus Latency™ (NoBL™) logic required

to enable consecutive Read/Write operations with data being

transferred on every clock cycle. This feature dramatically im-

proves the throughput of data through the SRAM, especially in

systems that require frequent Write/Read transitions. The

CY7C1354V25/CY7C1356V25 is pin compatible and function-

ally equivalent to ZBT devices.

• Pin compatible and functionally equivalent to ZBT™

• Supports 200-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 asynchronous OE

• Fully Registered (inputs and outputs) for pipelined op-

eration

• Byte Write capability

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

3.2 ns (200-MHz device).

• Common I/O architecture

• Single 2.5V power supply

• Fast clock-to-output times

— 3.2 ns (for 200-MHz device)

— 3.5 ns (for 166-MHz device)

— 4.2 ns (for 133-MHz device)

Write operations are controlled by the Byte Write Selects

(BWS_a–BWS_dfor CY7C1354V25 and BWS_a–BWS_bfor

CY7C1356V25) and a Write Enable (WE) input. All writes are

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

— 5.0 ns (for 100-MHz device)

• Clock Enable (CEN) pin to suspend operation

• Synchronous self-timed writes

• Available in 100 TQFP & 119 BGA Packages

• Burst Capability—linear or interleaved burst order

Three synchronous Chip Enables (CE₁, CE₂, CE₃) 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.

Functional Description

The CY7C1354V25 and CY7C1356V25 are 2.5V, 256K by 36

and 512K by 18 Synchronous-Pipelined Burst SRAMs, re-
