LY62L6416
64K X 16 BIT LOW POWER CMOS SRAM
Rev. 1.6
FEATURES
GENERAL DESCRIPTION
The LY62L6416 is a 1,048,576-bit low power CMOS
static random access memory organized as 65,536
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 : 1A (TYP.) LL/SL -version
Single 2.7V ~ 3.6V power supply
All inputs and outputs TTL compatible
Fully static operation
The LY62L6416 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
Tri-state output
Data byte control : LB# (DQ0 ~ DQ7)
UB# (DQ8 ~ DQ15)
Data retention voltage : 1.5V (MIN.)
Green package available
Package : 44-pin 400 mil TSOP II
48-ball 6mm x 8mm TFBGA
The LY62L6416 operates from a single power
supply of 2.7V ~ 3.6V and all inputs and outputs are
fully TTL compatible
