WEDPY256K72V-XBX
August 2004
Rev. 7
DESCRIPTION
The WEDPY256K72V-XBX employs high-speed, low-
power CMOS designs that are fabricated using an
advanced CMOS process. The 16Mb Synchronous
SRAMs integrate two 256K x 36 SRAMs into a single
PBGA package to provide 256K x 72 conguration. All
synchronous inputs are controlled by a positive-edge-
triggered single-clock input (CLK). The synchronous inputs
include all addresses, all data inputs, and active LOW chip
selects (CS#). Asynchronous inputs include the output
enable (OE1#/OE2#), clock (CLK).
* This product is subject to change without notice.
