Microchip 24AA128/24LC128/24FC128 Handbook
The 24AA128, 24LC128, and 24FC128 are 128‑Kbit (16K × 8) CMOS serial EEPROMs that operate over a wide voltage range and support low‑power applications. They are available in a variety of packages, including PDIP, SOIC, TSSOP, MSOP, and DFN.
Key features include low‑power operation, up to eight devices cascaded on a single I²C‑compatible bus, page‑write capability of 64 bytes, and robust endurance of one million erase/write cycles. Detailed electrical characteristics, pin functions, and bus timing are provided for designers.
