64 BURST PIPELINED HIGH-SPEED
CMOS STATIC RAM
Publication Release Date: August 1999
- 1 -
Revision A3
GENERAL DESCRIPTION
The W25P243A is a high-speed, low-power, synchronous-burst pipelined, CMOS static RAM
organized as 65,536
×
64 bits that operates on a single 3.3-volt power supply. A built-in two-bit burst
address counter supports both Pentium
burst mode and linear burst mode. The mode to be
executed is controlled by the LBO pin. Pipelining or non-pipelining of the data outputs is controlled by
the FT pin. A snooze mode can reduce power dissipation.
W25P243A supports 2T/1T mode, while disable data output within one cycle in a burst read when the
device is deselected by CE2/CE3 .
This device supports 3-1-1-1-2-1-1-1 in a two-bank, back-to-back burst read cycle.
