T68 K/S/R 1M Family Low Power 1M (128Kx8)-Bits Static RAM ¢ DESCRIPTION The T68K1M, T68S1M, and T68R1M device family is a low power and high performance CMOS SRAM organized as 131,072 words by 8 bits. It operates from 2.7V to 3.6V, 2.2V to 2.7V, and 1.65V to 2.2V. Easy memory expansion is provided by an active LOW chip enable 1 (/CE1), active HIGH chp enable 2 (CE2) and active LOW output enable (/OE) and three-state I/O drivers. Four control pins (/CE1, CE2, /OE, and /WE) fully control the operation mode of the T68 K/S/R 1M device family. An active LOW write enable signal (/WE active low) controls the write/read operation of the memory. When /CE1 and /WE inputs go LOW and CE2 input goes HIGH simultaneously, the device is in write mode and data on the 8 data pins (IO1~IO8) is written into the memory location specified by the address on address pins (A0~A16). When /CE1 and /OE inputs go LOW and CE2 and /WE input stay in HIGH state, the device is in read mode and data in the specified memory address is driven onto the 8 data pins. The 8 data pins will be in high -impedance state if both /OE and /WE pins are in HIGH (inactive) state. The T68 K/S/R 1M device family has an automatically power-down feature when the chip is deselected (/CE1 pin HIGH or CE2 pin LOW). The T68 K/S/R 1M device family is available in JEDEC standard 32-pin 450-mil SOP, 32-pin 8mmx20mm plastic TSOP, 32-pin 8mmx13.4mm plastic STSOP, and 36-ball 6mmx8mm BGA package, also for DICE. ¢ FEATURES — Operation voltage… … … … … … T68K1M… … … … … … … … … … … ................. 2.7V ~ 3.6V T68S1M… … … … … … … … … … … … … … … .. 2.2V ~ 2.7V T68R1M… … … … … … … … … … .................. 1.65V ~ 2.2V — Low active power and standby power — High access times: 70ns/85ns/100ns — TTL-compatible inputs and outputs — Easy memory expansion with /CE1, CE2 and /OE — Low data retention voltage… … … … … … … … … … ..2.0V (for K), 1.5V (for S), 1.0V (for R) — Auto power down when deselected 2003-REV 090 TIWIN Semiconductor • www.tiwin.com.tw • Tel :(886)-3 -5636031 • Fax:(886)-3-5644823 15 T68 K/S/R 1M ¢ PRODUCT FAMILY Part Number VCC Range Speed Operating Temperature Power Dissipation Operating Standby (ICC2, Max.)
