LY62W5128
Rev. 1.11
512K X 8 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The LY62W5128 is a 4,194,304-bit low power
CMOS static random access memory organized as
524,288 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 LY62W5128 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY62W5128 operates from a single power
supply of 2.7V ~ 5.5V and all inputs and outputs are
fully TTL compatible
FEATURES
Fast access time : 55/70ns
Low power consumption:
Operating current : 30/20mA (TYP.)
Standby current : 4μA (TYP.) LL-version
3μA (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
