GENERAL DESCRIPTION
The UT62L1024 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.
Easy memory expansion is provided by using two
chip enable input (
1CE
,CE2) and supports
industrial operating temperature range.
The UT62L1024 operates from a wide range
2.5V~3.6V power supply and all inputs and outputs
are fully TTL compatible.
