Preliminary W24LH8
32K
× 8 CMOS STATIC RAM
Publication Release Date: January 1999
- 1 -
Revision A2
GENERAL DESCRIPTION
The W24LH8 is a normal speed, very low power CMOS static RAM organized as 32768
× 8 bits that
operates on a wide voltage range from 2.7V to 3.6V power supply. The W24LH8 family, W24LH8-
70LE and W24LH8-70LI, can meet requirement of various operating temperature. This device is
manufactured using Winbond's high performance CMOS technology.
FEATURES
Low power consumption:
Active: 156 mW (max.)
Standby: 10.8
W (max.)
Access time: 70 nS
2.7V to 3.6V supply voltage
Fully static operation
All inputs and outputs directly TTL compatible
Three-state outputs
Battery back-up operation capability
Data retention voltage: 2V (min.)
Packaged in 28-pin 600 mil DIP, 330 mil SOP
and standard type one TSOP (8 mm
× 13.4
mm)
