PDM31034

1 Megabit 3.3V Static RAM

1 128K x 8-Bit

Revolutionary Pinout

Description

2 The PDM31034 is a high-performance CMOS static

RAM organized as 131,072 x 8 bits. Writing is

accomplished when the write enable (WE) and the

chip enable (CE) inputs are both LOW. Reading is

3 accomplished when WE remains HIGH and CE and

OE are both LOW.

The PDM31034 operates from a single +3.3V power

supply and all the inputs and outputs are fully TTL-

4 compatible.

The PDM31034 is available in a 32-pin 400 mil plas-

tic SOJ and 300 mil plastic SOJ, and a 32-pin plastic

TSOP (II) package in revolutionary pinout.
