DESCRIPTION

The EDI2CG272128VxxD1 is a Synchronous/Synchronous

Burst SRAM, 72 position DIMM (144 contacts) Module,

small outline. The Module contains four (4) Synchronous

Burst Ram Devices, packaged in the industry standard

JEDEC 14mmx20mm TQFP placed on a Multilayer FR4

Substrate. The module architecture is defined as a Sync/

Sync Burst, Flow-Through, with support for linear burst.

This module provides High Performance, 2-1-1-1 accesses

when used in Burst Mode, and used as a Synchronous

Only Mode, provides a high performance cost advantage

over BiCMOS aysnchronous device architectures.

Synchronous Only operations are performed via strapping

ADSC# Low, and ADSP# / ADV# High, which provides

for Ultra Fast Accesses in Read Mode while providing for

internally self-timed Early Writes.

Synchronous/Synchronous Burst operations are in relation

to an externally supplied clock, Registered Address,

Registered Global Write, Registered Enables as well

as an Asynchronous Output enable. This Module has

been defined for Quad Words in both Read and Write

Operations.
