LY625128
512K X 8 BIT LOW POWER CMOS SRAM
Rev. 2.5
FEATURES
GENERAL DESCRIPTION
The LY625128 is a 4,194,304-bit low power CMOS
static random access memory organized as 524,288
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 : 45/55/70ns
Low power consumption:
Operating current : 45/40/30mA (TYP.)
Standby current : 5μA@5V(TYP.) LL/SL version
3μA@3V(TYP.) SL version
Single 4.5V ~ 5.5V power supply
All inputs and outputs TTL compatible
Fully static operation
The LY625128 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 : 32-pin 450 mil SOP
