LY61L6416
Rev. 2.0
64K X 16 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The LY61L6416 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.
The LY61L6416 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY61L6416 operates from a single power
supply of 3.3V and all inputs and outputs are fully
TTL compatible
FEATURES
Fast access time : 8/10/12/15/20ns
Low power consumption:
Operating current : 115/105/95/85/70mA (TYP.)
Standby current :
0.6mA (TYP.)
100µA( (MAX. for 20ns LL version)
Single 3.3V 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 : 2.0V (MIN.)
Green package available
Package : 44-pin 400 mil TSOP-II
