TC55V8512J/FT-12,-15
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
• Fast access time (the following are maximum values)
TC55V8512J/FT-12:12 ns
TC55V8512J/FT-15:15 ns
• Low-power dissipation
(the following are maximum values)
Cycle Time 12 15 20 25 ns
Operation (max) 170 140 130 110 mA
Standby:4 mA (both devices)
• Single power supply voltage of 3.3 V ± 0.3 V
• Fully static operation
• All inputs and outputs are LVTTL compatible
• Output buffer control using OE
• Package:
SOJ36-P-400-1.27 (J)
(Weight: 1.35 g typ)
