The datasheet provides information about 93AA66A/B/C, 93LC66A/B/C, 93C66A/B/C devices, including features, temperature ranges, packages, etc.
The 93XX66 series are 4‑Kbit low‑voltage serial EEPROMs offered in multiple voltage options (1.8 V, 2.5 V, 5 V) and package types such as PDIP, SOIC, MSOP, SOT‑23 and TSSOP. They support 8‑bit or 16‑bit word organizations selectable via the ORG pin (for C‑versions) and are suited for low‑power, non‑volatile memory applications.
The datasheet details device features, pin assignments, absolute maximum ratings, DC and AC electrical characteristics, timing diagrams for erase, write, read and other commands, as well as the full instruction set and product identification information.
| Organization (A version) | 512 × 8‑bit |
|---|---|
| Industrial Temperature Range | -40 °C to +85 °C |
