Overview

The M24C04-RMN6TP is a 4 Kbit serial I2C bus EEPROM organized as 512 x 8 bits. It operates with a wide supply voltage range from 1.8V to 5.5V and supports a clock frequency of 400 kHz. This non-volatile memory is housed in an 8-lead SOIC package and is designed for reliable data retention in standard industrial temperature ranges from -40C to 85C.

Why Choose This Part

The device features an extremely low standby current of 1 uA, making it ideal for battery-powered applications. It offers a fast access time of 900 ns and is designed with an industry-standard I2C interface for high compatibility across various MCU platforms. The 1.8V to 5.5V operating range provides significant flexibility for both low-power and standard 5V logic designs.

Applications

Configuration Storage
Storing calibration constants, device IDs, and user preferences in embedded systems.
Parameter Logging
Recording system state information and operational parameters that must persist through power cycles.
Boot Initialization
Holding small look-up tables or initialization strings for microcontrollers during system start-up.

Getting Started

To interface with this EEPROM, connect the SCL and SDA lines to your microcontroller I2C peripheral with appropriate pull-up resistors. Ensure the hardware Write Control (WC) pin is tied to VSS if you require write operations. You can use standard I2C libraries like the Arduino Wire library or STM32 HAL I2C drivers to perform byte or page writes to the 512-byte memory space.
