PDM31548
Description
The PDM31548 is a high-performance CMOS static
RAM organized as 131,072 x 16 bits. The PDM31548
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 PDM31548 operates from a single 3.3V power
supply and all inputs and outputs are fully TTL-
compatible.
The PDM31548 is available in a 44-pin 400-mil plas-
tic SOJ and a plastic TSOP (II) package for high-
density surface assembly and is suitable for use in
high-speed
applications
requiring
high-speed
storage.
