UT6264C
8K X 8 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The UT6264C is a 65,536-bit low power CMOS static
random access memory organized as 8,192 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.( CE ,CE2) ,and supports low data
retention voltage for battery back-up operation with
low data retention current.
The UT6264C operates from a single 4.5V~5.5V
power supply and all inputs and outputs are fully TTL
compatible.
