Low Power 1M (128Kx8)-Bits Static RAM
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.
