FEATURES 2x128Kx72 Synchronous, Synchronous Burst Flow-Through Architecture Sequential Burst MODE Clock Controlled Registered Bank Enables (E1#, E2#) Clock Controlled Byte Write Mode Enable (BWE#) Clock Controlled Byte Write Enables (BW1# - BW8#) Clock Controlled Registered Address Clock Controlled Registered Global Write (GW#) Aysnchronous Output Enable (G#) Internally self-timed Write Gold Lead Finish 3.3V ± 10% Operation Access Speed(s): TKHQV=8.5, 9, 10, 12ns mon Data I/O High Capacitance (30pf) drive, at rated Access Speed Single total array Clock Multiple Vcc and Gnd 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. DESCRIPTION The EDI2AG272129Vxx D1 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 Sub strate. 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 Bi CMOS 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. - This product is under development, is not qualified or characterized and is subject to change or cancellation without notice.
