DESCRIPTION
The EDI2AG272129VxxD1 is a Synchronous/
Synchronous Burst SRAM, 72 position SO 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/Sycn Burst,
Flow-Through, with support for 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.
