Microchip Technology 24LC21-PC23 is a 1Kbit serial CMOS EEPROM organized as 128 words of 8 bits each. This component features a 2-wire serial interface compatible with I2C protocols, operating at clock frequencies up to 400kHz. Designed for robust data integrity, it offers a minimum data retention exceeding 200 years and guarantees 1,000,000 erase/write cycles. The device operates within a supply voltage range of 2.5V to 5.5V, with a nominal 3V. The 24LC21-PC23 is housed in an 8-pin PDIP package (R-PDIP-T8) suitable for through-hole mounting. It finds application in industrial control, consumer electronics, and automotive systems requiring non-volatile data storage.
