LY651024
128K X 8 BIT HIGH SPEED CMOS SRAM
Rev. 1.1
FEATURES
GENERAL DESCRIPTION
The LY651024 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.
Fast access time : 20ns
Low power consumption:
Operating current : 30mA (TYP.)
Standby current : 2μA (TYP.)
Single 5V power supply
All inputs and outputs TTL compatible
Fully static operation
The LY651024 is well designed for very 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 : 32-pin 300 mil SOJ
32-pin 8mm x 20mm TSOP-I
32-pin 8mm x 13.4mm STSOP
The LY651024 operates from a single power
supply of 3V~5V and all inputs and outputs are fully
TTL compatible
