LY62L12916
Rev. 1.0
128K X 16 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The LY62L12916 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.
The LY62L12916 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY62L12916 operates from a single power
supply of 2.7V ~ 3.6V and all inputs and outputs are
fully TTL compatible
FEATURES
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)
