LY62W1024
Rev. 1.11
128K X 8 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The LY62W1024 is a 1,048,576-bit low power CMOS
static random access memory organized as 131,072
words by 8 bits. It is fabricated using very high
performance, high reliability CMOS technology. Its
standby current is stable within the range of operating
temperature.
The LY62W1024 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY62W1024 operates from a single power
supply of 2.7V ~ 5.5V and all outputs are fully TTL
compatible.
FEATURES
Fast access time : 35/55/70ns
Low power consumption:
Operating current : 12/10/7mA (TYP.)
Standby current : 1A (TYP.) LL-version
0.8A (TYP.) SL-version
Single 2.7V ~ 5.5V power supply
All outputs TTL compatible
Fully static operation
Tri-state output
Data retention voltage : 1.5V (MIN.)
Green package available
