概述

Description

24FC128-I/ST is STMicroelectronics’ I2C serial EEPROM with 128 Kbit (16 Kbytes) of nonvolatile memory. It is accessed over the I2C two-wire bus (7-bit address with A0–A2 pins for the device address) and uses a 16‑bit memory address pointer to access the full memory array. Features include standard I2C speeds (up to 400 kHz), page write (commonly up to 32 bytes per write) with a write cycle time around 5 ms, low-power modes, and a write-protect (WP) input. Supply voltage typically 2.7–5.5 V; industrial temperature grades are available. Packages are 8-pin options (e.g., SOIC8, small-outline variants). Applications: nonvolatile storage for configuration data, logs, microcontroller data buffers, and other embedded storage needs in automotive, consumer, and industrial systems. For exact voltage and temperature ranges, timing, and packaging, consult the latest datasheet.
