LY611024
128K X 8 BIT HIGH SPEED CMOS SRAM
Rev. 1.6
FEATURES
GENERAL DESCRIPTION
The LY611024 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 : 12/15ns
Low power consumption:
Operating current : 50/40mA (TYP.)
Standby current : 1mA (TYP.)
2μA (TYP.) LL -version
Single 4.5V ~ 5.5V power supply
All inputs and outputs TTL compatible
Fully static operation
The LY611024 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 LY611024 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
