Description
The TC55V328J is a 262,144 bit CMOS high speed static random access memory organized as 32,768 words by 8 bits and
designed to operate from a single 3.3V supply. Toshiba's advanced CMOS technology and circuit design enable high speed, low
voltage operation.
The TC55V328J features low power dissipation when the SRAM is deselected using chip enable (CE) and has an output
enable input (OE) for fast memory access. It is suitable for use in high speed applications such as cache memory. All inputs and
outputs are LVTTL (low voltage TTL) compatible.
The TC55V328J is available in a 28-pin, 300mil SOJ package suitable for high density assembly.
