LY6225616
256K X 16 BIT LOW POWER CMOS SRAM
Rev. 1.1
FEATURES
GENERAL DESCRIPTION
The LY6225616 is a 4,194,304-bit low power CMOS
static random access memory organized as 262,144
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 : 35/45/55/70ns
Low power consumption:
Operating current : 50/45/40/30mA (TYP.)
Standby current : 5μA (TYP.)
Single 4.5V ~ 5.5V power supply
All inputs and outputs TTL compatible
Fully static operation
Tri-state output
Data byte control : LB# (DQ0 ~ DQ7)
UB# (DQ8 ~ DQ15)
The LY6225616 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
Data retention voltage : 2.0V (MIN.)
Lead free and green package available
Package : 44-pin 400 mil TSOP-II
48-ball 6mm x 8mm TFBGA
The LY6225616 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible
