Overview

The M24M02-DRMN6TP is a 2Mbit (256KB) I2C serial EEPROM designed for non-volatile data storage in low-power embedded systems. It supports a wide supply voltage range from 1.8V to 5.5V and features a 1MHz clock frequency for high-speed communication. This specific variant includes an additional identification page for storing sensitive application parameters and is housed in a space-efficient 8-pin SOIC package.

Why Choose This Part

The device offers a high memory density of 2Mbit in a standard SO8N footprint, making it suitable for applications with limited board space. It features low power consumption with a standby current of only 5uA and supports high-speed I2C communication up to 1MHz across the entire 1.8V to 5.5V voltage range.

Applications

Firmware Configuration Storage
Ideal for storing complex system parameters, calibration constants, and user settings that must persist through power cycles.
Data Logging
Utilized in industrial and consumer devices to log sensor data or event history where high endurance and reliability are required.
Device Identification
The dedicated identification page can be used to store MAC addresses, serial numbers, or security keys.

Getting Started

To interface with the M24M02-DRMN6TP, use any I2C-capable microcontroller with pull-up resistors on the SDA and SCL lines. Note that this 2Mbit device uses a 16-bit internal address plus an additional address bit in the device select code to access the full memory space. Software libraries for standard I2C EEPROMs can typically be used with minor adjustments to the addressing logic.
