LY62L102516
Rev. 1.0
1024K X 16 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The LY62L102516 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 LY62L102516 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY62L102516 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 : 10μA (TYP.) LL-version
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# (DQ0 ~ DQ7)
UB# (DQ8 ~ DQ15)
Data retention voltage : 1.2V (MIN.)
Green package available
Package : 48-pin 12mm x 20mm TSOP-I
48-ball 6mm x 8mm TFBGA
