UTRON
Rev. 1.0
8 KX 8 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The UT62W64C 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. its standby current is stable within the range of operating temperature. The UT62W64C is designed for low power application. It is particularly well suited for battery back-up nonvolatile memory application. The UT62W64C operates with wide range power supply and all inputs and outputs are fully TTL compatible
