Description

The CAT24C44 Serial NVRAM is a 256-bit nonvolatile memory organized as 16 words x 16 bits. The high speed Static RAM array is bit for bit backed up by a nonvolatile E²PROM array which allows for easy transfer of data from RAM array to E²PROM (STORE) and from E2PROM to RAM (RECALL). STORE operations are completed in 10ms max. and RECALL operations typically within 1.5µs. The CAT24C44 features unlimited RAM write operations either through external RAM writes or internal recalls from E²PROM. Internal false store protection circuitry prohibits STORE operations when V_CC is less than 3.5V (typical) ensuring E²PROM data integrity.

The CAT24C44 is manufactured using Catalyst's advanced CMOS floating gate technology. It is designed to endure 100,000 program/erase cycles (E2PROM) and has a data retention of 10 years. The device is available in JEDEC approved 8-pin plastic DIP and SOIC packages.
