1024K X 8 BIT LOW POWER CMOS SRAM
Rev. 1.0
FEATURES
GENERAL DESCRIPTION
The LY6210248 is a 8,388,608-bit low power CMOS
static random access memory organized as
1,048,576 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 : 55/70ns
Low power consumption:
Operating current : 45/30mA (TYP.)
Standby current : 8μA (TYP.) LL-version
Single 4.5V ~ 5.5V power supply
All inputs and outputs TTL compatible
Fully static operation
The LY6210248 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
Tri-state output
Data retention voltage : 1.5V (MIN.)
Green package available
Package : 44-pin 400 mil TSOP-II
48-ball 6mm x 8mm TFBGA
The LY6210248 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
