UT62L1024

 UTRON Rev. 1.7 FEATURES „ „ UT62L1024 128K X 8 BIT LOW POWER CMOS SRAM 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.( CE 1 ,CE2) It is particularly well suited for battery back-up nonvolatile memory application. The UT62L1024 operates from a single 2.7V~ 3.6V power supply and all inputs and outputs are fully TTL compatible. „ „ „ „ „ „ Access time : 35/55/70ns (max.)
