AT24C04C in 24LCxx / AT24Cxx I2C EEPROM Family
The AT24C04C series by Microchip Technology (formerly Atmel) is a family of 4,096-bit serial electrically erasable and programmable read-only memory (EEPROM) organized as 512 words of 8 bits each. These devices utilize the I2C (Two-Wire) serial interface, supporting standard-mode, fast-mode, and fast-mode plus protocols. Designed for low-power and low-voltage applications, they provide a reliable non-volatile storage solution for configuration data, calibration constants, and user preferences in space-constrained embedded systems.
Variants in This Sub-Family
Variants within the AT24C04C sub-family primarily differ based on package type and temperature ratings. Common packages include SOIC, TSSOP, UDFN, and VFBGA, catering to different space and thermal requirements. Part numbers like AT24C04C-SSHM-T denote specific industrial temperature ranges (-40°C to +85°C) and lead-free/halogen-free finishing. Some variants are specifically qualified for automotive applications (AEC-Q100), offering extended temperature stability for harsh environments.
