LY62W1024
Rev. 1.8
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 inputs and outputs are
fully TTL compatible
FEATURES
Fast access time : 35/55/70ns
Low power consumption:
Operating current : 12/10/7mA (TYP.)
Standby current : 1μA (TYP.) LL-version
0.8μA (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
Package : 32-pin 450 mil SOP
32-pin 600 mil P-DIP
32-pin 8mm x 20mm TSOP-I
32-pin 8mm x 13.4mm STSOP
