Description
The PDM41028 is a high-performance CMOS static
RAM organized as 262,144 x 4 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 PDM41028 operates from a single +5V power
supply and all the inputs and outputs are fully TTL-
compatible. The PDM41028 comes in two versions,
the standard power version PDM41028SA and a low
power version the PDM41028LA. The two versions
are functionally the same and only differ in their
power consumption.
The PDM41028 is available in a 28-pin 300-mil SOJ,
and a 28-pin 400-mil SOJ for surface mount
applications.
