32K x 8 LOW POWER CMOS STATIC RAM
.EATURES
• Access time: 45, 70 ns
• Low active power: 200 mW (typical)
• Low standby power
— 250 µW (typical) CMOS standby
— 28 mW (typical) TTL standby
• .ully static operation: no clock or refresh
required
• TTL compatible inputs and outputs
• Single 5V power supply
DESCRIPTION
The 1+51 IC62C256 is a low power, 32,768 word by 8-bit
CMOS static RAM. It is fabricated using 1+51's high-
performance, low power CMOS technology.
When CS is HIGH (deselected), the device assumes a standby
mode at which the power dissipation can be reduced down to
250 µW (typical) at CMOS input levels.
Easy memory expansion is provided by using an active LOW
Chip Select (CS) input and an active LOW Output Enable (OE)
input. The active LOW Write Enable (WE) controls both writing
and reading of the memory.
The IC62C256 is pin compatible with other 32K x 8 SRAMs in
330mil SOP or 8*13.4mm TSOP-1 package.

Note:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation of the
device at these or any other conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
