24C02
24C02 I2C-Compatible Serial EEPROM
Overview
The 24C02 is a 2K-bit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device organized as 256 x 8 bits. It features an I2C-compatible (Inter-Integrated Circuit) two-wire serial interface, making it ideal for applications requiring non-volatile memory with minimal pin count. The device operates across a wide voltage range and offers both hardware and software write protection features.
This EEPROM is designed for reliable operation in industrial temperature ranges and supports byte-wise and page-wise write operations (up to 16 bytes per page). The 24C02 is part of a family of serial EEPROMs with capacities ranging from 1K-bit to 512K-bit, providing design flexibility for various memory requirements.
