Description
The PDM41256 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 WEremains HIGH and CEand OEare both LOW.
The PDM41256 operates from a single +5V power supply and all the inputs and outputs are fully TTL compatible. The PDM41256 comes in two versions: the standard power version PDM41256SA and the low power version PDM41256LA. Both versions are functionally the same and differ only in their power consumption.
The PDM41256 is available in a 28-pin plastic TSOP (I) and a 28-pin 300-mil plastic SOJ.
