Standby : 2µA (typical) L-version
The UT621024 is a 1,048,576-bit low power
CMOS static random access memory
organized as 131,072 words by 8 bits. It is
fabricated using high performance, high
reliability CMOS technology.
1µA (typical) LL-version
„ Single 5V power supply
„ All inputs and outputs TTL compatible
„ Fully static operation
„ Three state outputs
„ Data retention voltage : 2V (min.)
„ Package : 32-pin 600 mil PDIP
32-pin 450 mil SOP
32-pin 8mmx20mm TSOP-1
32-pin 8mmx13.4mm STSOP
The UT621024 is designed for low power
application. It is particularly well suited for
battery back-up nonvolatile memory
application.
The UT621024 operates from a single 5V
power supply and all inputs and outputs are
fully TTL compatible.
