PDM31256

3.3V 256K Static RAM

32K x 8-Bit

Features

Description

The PDM31256 is a high-performance CMOS static

RAM organized as 32,768 x 8 bits. Writing to this

device is accomplished when the write enable (WE)

and the chip enable (CE) inputs are both LOW.

Reading is accomplished when WE remains HIGH

and CE and OE are both LOW.

The PDM31256 operates from a single +3.3V power

supply and all the inputs and outputs are fully TTL-

compatible.

The PDM31256 is available in a 28-pin 300-mil

plastic SOJ and a 28-pin plastic TSOP (I).

High-speed access times

Com’l: 10, 12, 15 and 20ns

Ind’l: 12, 15 and 20ns

Low power operation (typical)

- PDM31256SA

Active: 200 mW

Standby: 15mW

Single +3.3V (±0.3V) power supply

TTL-compatible inputs and outputs

Packages

Plastic SOJ (300 mil) - SO

Plastic TSOP (I) - T
