CAT24C44LI Description

Short technical summary and product information.

The CAT24C44LI from On Semiconductor is a 256-bit serial Non-Volatile Static RAM (NVSRAM) organized as 16 words by 16 bits. This device features a high-speed Static RAM array backed by a nonvolatile EEPROM array, allowing for data transfer between RAM and EEPROM via STORE and RECALL operations. It operates from a single 5V supply with a voltage range of 4.5V to 5.5V and supports an SPI interface with a clock frequency of up to 1MHz.

 

Designed for reliability, the CAT24C44LI offers 10 years of data retention and 100,000 program/erase cycles for the EEPROM. It consumes low CMOS power, with a maximum active current of 3mA and a standby current of 30µA. The device includes power-up/down protection and auto-recall on power-up. It is available in an 8-lead DIP package suitable for through-hole mounting.

 

This NVSRAM is designed for applications requiring non-volatile data storage combined with the speed of SRAM. Its operating temperature range is -40°C to 85°C (TA), making it suitable for various demanding environments. The device supports JEDEC standard pinouts and features CMOS and TTL compatible I/O.
