DESCRIPTION
The EDI2CG472128VxxD2 is a Synchronous/Synchronous
Burst SRAM, 84 position Dual Key; Double High DIMM (168
contacts) Module, organized as 4x128Kx72. The Module
contains eight (8) 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 either linear or sequential 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.
