TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
524,288-WORD BY 8-BIT CMOS STATIC RAM
DESCRIPTION
The TC55V8512J/FT is a 4,194,304-bit high-speed static random access memory (SRAM) organized as 524,288
words by 8 bits. Fabricated using CMOS technology and advanced circuit techniques to provide high speed, it
operates from a single 3.3 V power supply. Chip enable ( CE ) can be used to place the device in a low-power mode,
and output enable ( OE ) provides fast memory access. This device is well suited to cache memory applications
where high-speed access and high-speed storage are required. All inputs and outputs are directly LVTTL
compatible. The TC55V8512J/FT is available in plastic 36-pin SOJ and 44-pin TSOP with 400mil width for high
density surface assembly.
FEATURES
