Overview

The M24C16-WMN6TP is a 16-Kbit serial EEPROM from STMicroelectronics offering non-volatile I2C storage in a very compact package. It provides small, low-pin-count storage for configuration, calibration, and small data logging in space-constrained designs. The device is part of STs M24C16 family which targets applications that need a simple I2C EEPROM.

Why Choose This Part

Small footprint and an I2C serial interface make the M24C16-WMN6TP easy to integrate into space- and pin-constrained designs. As a widely used EEPROM family, it is supported by mature software libraries and basic tooling (logic analyzers, I2C scanners), which reduces development time. Multiple package options across the family let you pick the best mechanical fit without changing the memory interface in your system.

Applications

Configuration and parameter storage
Store device settings, boot parameters, and calibration constants that must persist across power cycles.
Sensor calibration and lookup tables
Keep per-unit calibration data or small lookup tables for sensors and analog front-ends in space-limited assemblies.
Small event logging and counters
Record occasional counters, error logs, or usage statistics where a few kilobits of non-volatile storage are sufficient.
Manufacturing data and serial IDs
Store board-level manufacturing information, serial numbers, or product revision data for inventory and service.

Getting Started

No dedicated dev board is required - any microcontroller dev board with I2C (Arduino, STM32 Nucleo, ESP32, etc.) can communicate with this EEPROM. Use common I2C libraries (for example Wire on Arduino or HAL drivers for STM32) and a logic analyzer or I2C bus sniffer to debug transactions. Consult STs datasheet and application notes for addressing, timing and recommended write/read sequences.
