FEATURES
GENERAL DESCRIPTION
The LY69L25616A 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 : 45/55ns
Low power consumption:
Operating current : 12mA (TYP.)
Standby current : 2.5A (TYP.)
Single 2.7V ~ 3.6V power supply
ECC : 1-bit error correction per byte
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.)
Green package available
Package : 48-ball 6mm*8mm TFBGA
44-pin 400mil TSOP II
The LY69L25616A embeds error-correcting code
(ECC) which can correct single-bit error per byte. It
is well designed for low power application, and
particularly well suited for battery back-up
nonvolatile memory application.
The LY69L25616A operates from a single power
supply of 2.7V ~ 3.6V and all inputs and outputs are
fully TTL compatible
