The EDI2AG272128VxxD1 is a Synchronous/Synchronous
Burst SRAM, 72 position DIMM (144 contacts) Module,
organized as 2x128Kx72. 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 with full flexibility, which allows individual control
of each of the eight bytes, as well as Quad Words in both
Read and Write Operations.
