CAT24C44VI Description

Short technical summary and product information.

The CAT24C44VI is a 256-bit serial non-volatile CMOS static RAM manufactured by ON Semiconductor. It is organized as 16 words by 16 bits, providing a reliable non-volatile memory solution. The device features an SPI interface with a clock frequency of up to 1 MHz, making it suitable for various embedded applications.

 

This NVSRAM operates from a single 5V supply (4.5V to 5.5V) and offers low CMOS power consumption. Key features include infinite EEPROM to RAM recall, power-up/down protection, and 10-year data retention. The memory array is backed by an EEPROM, allowing for easy data transfer between RAM and EEPROM via STORE and RECALL operations. STORE operations complete in 10ms maximum, while RECALL operations are typically within 1.5µs.

 

The CAT24C44VI is designed for endurance, with 100,000 program/erase cycles for the EEPROM. It is available in an 8-lead SOIC package, suitable for surface mount applications. The operating temperature range is -40°C to 85°C (TA), catering to commercial and industrial environments.
