PDM31564
Description
The PDM31564 is a high-performance CMOS static
RAM organized as 262,144 x 16 bits. The PDM31564
features low power dissipation using chip enable
(CE) and has an output enable input (OE) for fast
memory access. Byte access is supported by upper
and lower byte controls.
The PDM31564 operates from a single 3.3V power
supply and all inputs and outputs are fully TTL-
compatible.
The PDM31564 is available in a 44-pin 400-mil plas-
tic SOJ and a plastic TSOP package for high-density
surface assembly and is suitable for use in high-
speed applications requiring high-speed storage.
