Overview

The M24C02-WMN6P is a 2-Kbit non-volatile I2C EEPROM organized as 256 x 8 bits. It operates across a wide voltage range of 2.5V to 5.5V and supports a 400 kHz clock frequency, making it a standard choice for storing configuration data and small lookup tables. The device is housed in a compact 8-lead SO8N package and features low power consumption with a 3uA standby current.

Why Choose This Part

This EEPROM offers a high degree of reliability with an operating temperature range of -40 to 85 degrees Celsius and a very low standby current of 3uA at 5.5V. Its 400 kHz I2C interface ensures compatibility with almost any modern microcontroller while the SO8N package provides a standard footprint for easy PCB layout.

Applications

Device Configuration Storage
Storing MAC addresses, serial numbers, and calibration constants that must persist through power cycles.
User Preference Logging
Saving user-defined settings like display brightness, volume levels, or language preferences in consumer electronics.
Firmware Parameter Tuning
Holding PID coefficients or sensor offset values that need occasional updates during system calibration.

Getting Started

To interface with the M24C02-WMN6P, connect the SCL and SDA lines to your microcontroller's I2C peripheral with appropriate pull-up resistors. Use standard I2C libraries to perform byte or page writes to the 256-byte memory space, ensuring you observe the internal write cycle timing (typically 5ms) between operations. The hardware Write Protect (WC) pin can be tied to VCC to prevent accidental data overwrites.
