Overview
TOSHIBA 1l:55B8128P/]-12/15/20 SILICON GATE BiCMOS 131,072 WORD x 8 BIT BiCMOS STATIC RAM Description The TC55B8128P/J is a 1,048,576 bit high speed BiCMOS static random access memory organized as 131,072 words by 8 bits and operated from a single 5V supply.
Toshiba's BiCMOS technology and advanced circuit design enable.
!:!!9h speed operation.
The TC55B8128P/J features low power dissipation when the device is deselected using chip enable (CE), and has an output enable input (OE) for fast memory access.
The TC55B8128P/J is suitable for use in high speed applications such as cache memory and high speed storage.
All inputs and outputs are TIL compatible.
The TC55B8128P/J is available in a 400mil width, 32-pin DIP and SOJ suitable for high density surface assembly.
