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
