CY7C1351G

PRELIMINARY

4-Mbit (128K x 36) Flow-through SRAM

with NoBL™ Architecture

Functional Description^[1]

Features

• Can support up to 133-MHz bus operations with zero

wait states

The CY7C1351G is a 3.3V, 128K x 36 Synchronous

Flow-through Burst SRAM designed specifically to support

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

insertion of wait states. The CY7C1351G 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

improves the throughput of data through the SRAM, especially

in systems that require frequent Write-Read transitions.

— Data is transferred on every clock

• Pin compatible and functionally equivalent to ZBT™

devices

• Internally self-timed output buffer control to eliminate

the need to use OE

• Registered inputs for flow-through operation

• Byte Write capability

All synchronous inputs pass through input 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 previous clock cycle.

Maximum access delay from the clock rise is 6.5 ns (133-MHz

device).

• 128K x 36 common I/O architecture

• 2.5V / 3.3V I/O power supply

• Fast clock-to-output times

— 6.5 ns (for 133-MHz device)

Write operations are controlled by the four Byte Write Select

(BW_[A:D]) and a Write Enable (WE) input. All writes are

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

— 7.5 ns (for 117-MHz device)

— 8.0 ns (for 100-MHz device)

Three synchronous Chip Enables (CE₁, CE₂, CE₃) and an

asynchronous Output Enable (OE) provide for easy bank

selection and output tri-state control. In order to avoid bus

contention, the output drivers are synchronously tri-stated

during the data portion of a write sequence.

• Clock Enable (CEN) pin to suspend operation

• Synchronous self-timed writes

• Asynchronous Output Enable

• Lead-Free 100 TQFP and 119 BGA packages

• Burst Capability—linear or interleaved burst order

• Low standby power
