AT24C02B is Microchip's 2Kbit EEPROM, which can be used in many industrial and commercial applications and is suitable for applications that require low power and low voltage operation. The device has 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-MAP (MLP 2x3), 5-lead SOT23, 8-lead TSSOP and 8-ball dBGA2 package.
The AT24C02B is a 2‑Kbit (2048‑bit) serial EEPROM organized as 256 × 8 bits and accessed via a two‑wire I²C‑compatible interface. It is offered in multiple compact packages, including PDIP, SOIC, Ultra‑Thin Mini‑MAP, SOT23, TSSOP, and 8‑ball dBGA2.
Key features include low‑voltage operation from 1.8 V to 5.5 V, high reliability with 1 million write cycles, 100‑year data retention, and a standby current of less than 1 mA. The datasheet details absolute maximum ratings, DC and AC electrical characteristics, timing diagrams, and package dimensions.
