LY62L12816
128K X 16 BIT LOW POWER CMOS SRAM
Rev. 1.2
GENERAL DESCRIPTION
FEATURES
The LY62L12816 is a 2,097,152-bit low power
CMOS static random access memory organized
as 131,072 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 : 45/55/70ns
Low power consumption:
Operating current : 23/20/18mA (TYP.)
Standby current : 1μA (TYP.) LL/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)
The LY62L12816 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 : 44-pin 400 mil TSOP-II
48-ball 6mm x 8mm TFBGA
The LY62L12816 operates from a single
power supply of 2.7V ~ 3.6V and all inputs and
outputs are fully TTL compatible
