IC62C1024L

IC62C1024L

128K x 8 LOW POWER CMOS STATIC RAM

FEATURES

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

Fully static operation: no clock or refresh required

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 highperformance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields higher performance and low power consumption devices.

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.

TTL compatible inputs and outputs

Single 5V (±10%) power supply

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.
