LY65W64
8K X 8 BIT HIGH SPEED CMOS SRAM
Rev. 1.1
FEATURES
GENERAL DESCRIPTION
The LY65W64 is a 65,536-bit high speed CMOS
static random access memory organized as 8,192
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.
Fast access time : 25ns
Low power consumption:
Operating current : 30mA (TYP.)
Standby current : 1μA (TYP.)
Single 3~5V power supply
All inputs and outputs TTL compatible
Fully static operation
The LY65W64 is well designed for high speed
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
Tri-state output
Data retention voltage : 2.0V (MIN.)
Green package available
Package : 28-pin 300 mil SOJ
28-pin 8mm x 13.4mm STSOP
The LY65W64 operates from a single power
supply of 3~5V and all inputs and outputs are fully
TTL compatible
