This document describes the features and characteristics of the 24AA00/24LC00/24C00 series products from Microchip Technology Inc., including low-power CMOS technology, 2-wire serial interface, self-timed write cycle, ESD protection, data retention, etc.
The 24AA00/24LC00/24C00 family are 128‑bit serial EEPROMs organized as 16 bytes × 8 bits. They are intended for storing calibration values, ID numbers, or other small amounts of non‑volatile data in a wide range of applications. The devices operate from low‑voltage supplies and feature very low standby current.
The handbook details the device packages, pin descriptions, bus protocol, write and read operations, electrical specifications, and code‑protection information. It also includes tables of absolute maximum ratings, DC and AC characteristics, and timing diagrams to aid designers in implementing the parts.
