Microchip AT24C02C 2Kbit I²C Serial EEPROM SOIC-8

The Microchip AT24C02C-SSHM-B is a 2Kbit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) organised as 256 words of 8 bits each. It uses a 2-wire I²C-compatible interface for communication, supporting bidirectional data transfer and clock frequencies up to 1MHz. This device is optimised for industrial and commercial applications where low power and low voltage operation are critical. The entire family operates from 1.7V to 5.5VCC, making it versatile for various electronic designs.

The EEPROM includes a cascading feature that allows up to eight devices to share a common 2-wire bus, simplifying system expansion. Schmitt trigger and filtered inputs provide enhanced noise suppression. A write protect pin ensures hardware data protection, and the self-timed write cycle (5ms maximum) simplifies programming. The device offers high reliability with endurance of 1,000,000 write cycles and data retention of 100 years. It is a green product, free from antimony and bromine.
