The document describes the features and characteristics of the AT93C86A EEPROM, including medium-voltage and standard-voltage operation, automotive temperature range, user selectable internal organization, serial interface, sequential read operation, noise suppression, high reliability, etc.
The AT93C86A is a 16‑Kbit (16384‑bit) serial electrically erasable programmable read‑only memory (EEPROM) offered in 8‑lead JEDEC SOIC and 8‑lead TSSOP packages. It operates from 2.7 V to 5.5 V and is rated for automotive temperature ranges from –40 °C to +125 °C.
The device uses a three‑wire serial interface (CS, DI, DO, SK) and supports read, write, erase, and bulk‑program operations with self‑timed cycles. The datasheet includes pin‑out tables, absolute‑maximum ratings, timing diagrams, electrical characteristics, and mechanical dimensions.
