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 deï¬ned 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
deï¬ned with full ï¬exibility, which allows individual control
of each of the eight bytes, as well as Quad Words in both
Read and Write Operations.
