AT24C02D in 24LCxx / AT24Cxx I2C EEPROM Family
The AT24C02D family from Microchip Technology (formerly Atmel) consists of 2-Kbit serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) devices. These components utilize the industry-standard I2C (2-wire) serial interface and are optimized for low-power and low-voltage applications. As part of the broader AT24Cxx lineage, they provide highly reliable non-volatile storage for configuration data, user preferences, and calibration constants in a variety of space-constrained and battery-operated embedded systems.

Variants within the AT24C02D family differ primarily by package type and operating temperature ranges. Available footprints include the common 8-lead SOIC and TSSOP, as well as ultra-compact 8-pad UDFN and 5-lead SOT-23 packages. Some variants are specified for standard industrial temperature ranges (-40C to +85C), while others are offered in PDIP for through-hole prototyping or specific automotive-grade qualified versions with varying voltage tolerances.
