Description  
Features  
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.  
High-speed access times  
Com’l: 10, 12, 15 and 20ns  
Ind’l: 12, 15 and 20ns  
Low power operation (typical)  
- PDM31256SA  
3
Active: 200 mW  
Standby: 15mW  
The PDM31256 operates from a single +3.3V power  
supply and all the inputs and outputs are fully TTL-  
compatible.  
Single +3.3V (±0.3V) power supply  
TTL-compatible inputs and outputs

The PDM31256 is available in a 28-pin 300-mil  
plastic SOJ and a 28-pin plastic TSOP (I).
