LY62L102516A
Rev. 1.0
1024K x 16 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The LY62L102516A is a 16,777,216-bit low power
CMOS static random access memory organized as
1,048,576 words by 16 bits. It is fabricated using
very high performance, high reliability CMOS
technology. Its standby current is stable within the
range of operating temperature.
The LY62L102516A is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY62L102516A operates from a single
power supply of 2.7V ~ 3.6V and all inputs and
outputs are fully TTL compatible.
FEATURES
Fast access time : 55/70ns
Low power consumption:
Operating current : 45/30mA (TYP.)
Standby current : 4μA (TYP.) SL-version
Single 2.7V ~ 3.6V power supply
All inputs and outputs TTL compatible
Fully static operation
Tri-state output
Data byte control :
LB# controlled DQ0 ~ DQ7
UB# controlled DQ8 ~ DQ15
Data retention voltage : 1.2V (MIN.)
Green package available
Package : 48-pin 12mm x 20mm TSOP-I
