Product Summary
The W25P243AF-4A 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 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. The W25P243AF-4A supports 2T/1T mode, while disable data output within one cycle in a burst read when the W25P243AF-4A is deselected by CE2/CE3.
