Description
The TC55328AP/AJ is a 262,144 bit high speed CMOS static random access memory organized as 32,768 words by 8 bits and
operated from a single 5V supply. Toshiba's advanced CMOS technology and circuit design enable high speed operation.
The TC55328AP/AJ features low power dissipation when the device is deselected using chip enable (CE) and has an output
enable input (OE) for fast memory access. Also, the device power between memory accesses is reduced by an automatic power
inputs
down circuit.
The TC55328AP/AJ is suitable for use in high speed applications such as cache memory and high speed storage. All
and outputs are TTL compatible.
The TC55328AP/AJ is available in a 300mil width, 28-pin DIP and SOJ suitable for high density surface assembly.
