Description
The TC55329AP/AJ is a 294,912 bit high speed CMOS static random access memory organized as 32,768 words by 9 bits and
operated from a single 5V supply. Toshiba's advanced CMOS technology and circuit design enable high speed operation.
The TC55329AP/AJ features low power dissipation when the device is deselected using chip enable (CE1, CE2) and has an
output enable input (OE) for fast memory access. Also, the device power between memory accesses is reduced by an automatic
power down circuit.
The TC55329AP/AJ is suitable for use in high speed applications such as cache memory and high speed storage. All inputs
and outputs are TTL compatible.
The TC55329AP/AJ is available in a 300mil width, 32-pin DIP and SOJ suitable for high density surface assembly.
