1 / 10 page TC55V8512J/FT-12,-15 2001-12-19 1/10 • 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) TSOP II44-P-400-0.80 (FT) (Weight: 0.45 g typ) 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) PIN ASSIGNMENT (TOP VIEW) PIN NAMES 36 PIN SOJ 44 PIN TSOP A0 to A18 Address Inputs I/O1 to I/O8 Data Inputs/Outputs CE Chip Enable Input WE Write Enable Input OE Output Enable Input VDD Power ( +3.3 V) GND Ground NC No Connection NU Not Usable (Input) (TC55V8512J) (TC55V8512FT) A17 A3 A2 A1 A0 I/O1 I/O2 VDD GND I/O3 I/O4 A16 A15 A14 A13 A18 NC A4 A5 A6 A7 I/O8 I/O7 GND VDD I/O6 I/O5 A8 A9 A10 A11 A12 NU 1 36 2 35 3 34 4 33 5 32 6 31 7 30 8 29 9 28 10 27 11 26 12 25 13 24 14 23 15 22 16 21 17 20 18 19 CE OE WE 1 44 2 43 3 42 4 41 5 40 6 39 7 38 8 37 9 36 10 35 11 34 12 33 13 32 14 31 15 30 16 29 17 28 18 27 19 26 20 25 21 24 22 23 NC NC A17 A3 A2 A1 A0 I/O1 I/O2 VDD GND I/O3 I/O4 A16 A15 A14 A13 A18 NC NC NC NC NC A4 A5 A6 A7 I/O8 I/O7 GND VDD I/O6 I/O5 A8 A9 A10 A11 A12 NU NC NC OE CE WE |
