This datasheet provides the features and characteristics of AT24C16B, including pin definition, function features, package form, application scenarios, etc.
The AT24C16B is a 16‑Kbit serial EEPROM offering low‑voltage (1.8 V) to standard‑voltage (5.5 V) operation. It features a two‑wire serial interface, 16‑byte page write mode, partial page writes, and a write‑protect pin for hardware data protection. The device is available in multiple compact packages such as 8‑lead PDIP, SOIC, TSSOP, ULA, and others.
The datasheet details pin functions, memory organization, timing diagrams, and electrical parameters. Key characteristics include a 1 M write‑cycle endurance, 100‑year data retention, supply currents of 1‑3 mA, and a maximum write cycle time of 5 ms. Absolute maximum ratings and revision history are also provided.
