This document describes the features and characteristics of the AT34C02C model, including permanent and reversible software write protection, hardware write protection, standard-voltage operation, internal organization, two-wire serial interface, Schmitt trigger with filtered inputs, bidirectional data transfer protocol, 400 kHz compatibility, 16-byte page write modes, partial page writes, self-timed write cycle, and high reliability.
This document provides a complete description of the AT34C02C 2‑Kbit serial EEPROM, including its permanent and reversible software write‑protect functions, hardware write‑protect option, and two‑wire serial interface operation. It lists package options (8‑lead SOIC and TSSOP) and the voltage range of 2.5 V to 5.5 V.
Key sections cover absolute maximum ratings, pin descriptions, write‑protect modes, DC and AC electrical characteristics, memory organization, write and page write procedures, standby mode, and timing diagrams for start/stop conditions and acknowledge polling.
