Microchip 93AA/93LC/93C EEPROM Series Datasheet

About this manual

The 93AA/93LC/93C series are low‑power CMOS EEPROM devices that support a 3‑wire Microwire interface. They are offered in capacities from 1 Kb to 16 Kb, with optional ORG pins for 8‑ or 16‑bit word architectures, and feature automatic erase before write, standby data protection, and up to 1 000 000 write/erase cycles.

The family is available in multiple lead‑frame packages—including PDIP, SOIC, MSOP, TSSOP, SOT‑23, and DFN—with both lead‑free and tin‑lead finishes. Operating voltage ranges from 1.8 V to 5.5 V (industrial) or 2.5 V to 5.5 V (automotive), and temperature ratings cover –40 °C to +85 °C (industrial) and –40 °C to +125 °C (automotive). This manual is written in Chinese.
