LY6164
8K X 8 BIT HIGH SPEED CMOS SRAM
Rev. 1.4
FEATURES
GENERAL DESCRIPTION
The LY6164 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 : 8/10/12/15ns
Low power consumption:
Operating current : 110/100/90/80mA (TYP.)
Standby current : 1mA (TYP.)
Single 5V power supply
All inputs and outputs TTL compatible
Fully static operation
The LY6164 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 300 mil Skinny P-DIP
The LY6164 operates from a single power supply
of 5V and all inputs and outputs are fully TTL
compatible
