24LC04B in 24LCxx / AT24Cxx I2C EEPROM Family
The 24LC04B series, manufactured primarily by Microchip Technology, is a 4-Kbit Electrically Erasable PROM designed for low-power and low-voltage applications. Utilizing a standard I2C-compatible two-wire serial interface, it operates across a broad voltage range of 2.5V to 5.5V. This family is a staple in the embedded industry for storing configuration data and non-volatile parameters, offering robust data retention of over 200 years and endurance exceeding one million erase/write cycles.
