AT24C02B in 24LCxx / AT24Cxx I2C EEPROM Family
The AT24C02B family, manufactured primarily by Microchip Technology (following its acquisition of Atmel), consists of 2-Kbit serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) devices. These components utilize a standard 2-wire I2C interface, organized as 256 words of 8 bits each. Engineered for low-power and low-voltage operation, they serve as a reliable solution for non-volatile data storage in industrial and consumer applications where pin count and power consumption are critical design constraints.
Variants in This Sub-Family
Variants within the AT24C02B sub-family are primarily distinguished by their physical packaging and operating temperature grades. Standard package options include 8-lead SOIC, TSSOP, UDFN, and SOT23-5, catering to different PCB density requirements. Variations also exist in temperature qualification, ranging from industrial-grade (-40 to 85 Celsius) to automotive-grade extended ranges, though the core silicon and internal logic remain functionally identical across these physical implementations.
