This document describes the features and characteristics of the M24C16, M24C08, M24C04, M24C02, and M24C01 serial I²C bus EEPROMs, including a two-wire I2C serial interface supporting 400kHz protocol, single supply voltage range, write control input, byte and page write modes, random and sequential read modes, self-timed programming cycle, automatic address incrementing, enhanced ESD/latch-up behavior, over 1 million erase/write cycles, and over 40 years of data retention.
The M24Cxx family are I²C‑compatible serial EEPROM devices ranging from 1 Kb to 16 Kb. They use a two‑wire I²C interface, support up to 400 kHz bus speed, and are available in several supply‑voltage ranges (4.5‑5.5 V for standard parts, 2.5‑5.5 V for ‑W, 1.8‑5.5 V for ‑R). The devices provide byte‑write, page‑write (up to 16 bytes), random and sequential read modes, and include a power‑on‑reset circuit to protect data.
The document details electrical characteristics, package dimensions (PDIP8, SO8, TSSOP8, UFDFPN8, etc.), pin functions, timing diagrams, and absolute maximum ratings. It also lists ordering information, revision history, and compliance notes for RoHS‑compatible devices.
