GENERAL DESCRIPTION

The W25P243A is a high-speed, low-power, synchronous-burst pipelined, CMOS static RAM organized as 65,536 X 64 bits that operates on a single 3.3-volt power supply. A built-in two-bit burst address counter supports both Pentiumä 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.
