128K x 8 LOW POWER CMOS STATIC RAM
High-speed access time: 35, 45, 55, 70 ns Low active power: 450 mW (typical) Low standby power: 150 µW (typical) CMOS standby Output Enable (OE) and two Chip Enable (CE1 and CE2) inputs for ease in applications .ully static operation: no clock or refresh required TTL compatible inputs and outputs Single 5V (±10%) power supply
performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields higher performance and low power consumption devices.
DESCRIPTION The 1+51 IC62C1024L is a low power,131,072-word by 8-bit CMOS static RAM. It is fabricated using 1 +51 's high-
When CE1 is HIGH or CE2 is LOW (deselected), the device assumes a standby mode at which the power dissipation can be reduced by using CMOS input levels. Easy memory expansion is provided by using two Chip Enable inputs, CE1 and CE2. The active LOW Write Enable (WE) controls both writing and reading of the memory. The IC62C1024L is available in 32-pin 600mil DIP, 450mil SOP and 8*20mm TSOP-1 packages.

Tested with the load in .igure 1b. Transition is measured ±500 mV from steady-state voltage. Not 100% tested. 3. The internal write time is defined by the overlap of CE1 LOW, CE2 HIGH and WE LOW. All signals must be in valid states to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the rising or falling edge of the signal that terminates the Write. 4. Tested with OE HIGH.
