24LC256 in 24LC/24AA/AT24 EEPROM Family
The 24LC256 is a 256-Kbit serial Electrically Erasable PROM (EEPROM) manufactured primarily by Microchip Technology. It is designed for low-power applications and operates over a wide voltage range typically from 1.7V to 5.5V. Utilizing a two-wire I2C-compatible serial interface, this component is a staple in the embedded industry for non-volatile storage, offering high endurance and long-term data retention for systems requiring persistent parameter storage without the overhead of NOR flash architectures.
