LY62L12816
Rev. 1.1
128K X 16 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
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.
The LY62L12816 is well designed for low power
application, and particularly well suited for
battery back-up nonvolatile memory application.
The LY62L12816 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 : 20μA (TYP.) L-version
1μA (TYP.) LL-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)
Data retention voltage : 1.5V (MIN.)
Lead free and green package available
Package : 44-pin 400 mil TSOP-II
48-ball 6mm x 8mm TFBGA
