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.
