Overview

The M24256-BRMN6P is a 256Kbit industrial-grade I2C EEPROM organized as 32,768 x 8 bits. It operates across a wide supply voltage range of 1.8V to 5.5V and supports the Fast-mode Plus I2C protocol with clock frequencies up to 1 MHz.

Why Choose This Part

This device features an ultra-low standby current of only 1 uA, making it ideal for battery-operated systems. It offers robust data retention and high reliability across a temperature range of -40 to +85 degrees Celsius, with 5V tolerant inputs even when operating at lower supply voltages.

Applications

Parameter Storage
Storing calibration data, user preferences, and configuration settings in industrial and consumer devices.
Event Logging
Recording system logs and error codes in low-power applications where data must be retained during power cycles.
Firmware Metadata
Storing bootloader parameters, hardware revision codes, and MAC addresses for networking equipment.

Getting Started

To interface with the M24256-BRMN6P, connect the SCL and SDA lines to a microcontroller I2C peripheral with appropriate pull-up resistors. Ensure the three chip-enable pins (E0, E1, E2) are tied to VCC or GND to set the device address, and use standard I2C libraries to perform byte or page writes.

Also Consider

24LC256-I/SN MCHPMicrochip Technology - A widely available alternative with similar 256Kbit density and 8-SOIC footprint, though limited to 400kHz at some voltage ranges.
AT24C256C Microchip/Atmel - Offers 1MHz compatibility at higher voltage levels and is a drop-in replacement for many I2C EEPROM applications.
CAT24C256WI-GT3 ONonsemi - Provides a 64-byte page write buffer and similar low-power characteristics in an 8-SOIC package.
