LY62102516
1024K X 16 BIT LOW POWER CMOS SRAM
Rev. 0.3
FEATURES
GENERAL DESCRIPTION
The LY62102516 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.
Fast access time : 55/70ns
Low power consumption:
Operating current : 45/30mA (TYP.)
Standby current : 10μA (TYP.) LL-version
Single 4.5V ~ 5.5V power supply
All inputs and outputs TTL compatible
Fully static operation
Tri-state output
Data byte control : LB# (DQ0 ~ DQ7)
UB# (DQ8 ~ DQ15)
The LY62102516 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
Data retention voltage : 1.5V (MIN.)
Green package available
Package : 48-pin 12mm x 20mm TSOP-I
48-ball 6mm x 8mm TFBGA
The LY62102516 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
