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.
