Overview

The M95512-RMN6P is a 512 Kbit non-volatile serial EEPROM organized as 64K x 8 bits. It operates over a wide voltage range of 1.8V to 5.5V and utilizes a high-speed SPI bus interface capable of clock frequencies up to 16 MHz. This industrial-grade memory is housed in an 8-lead SOIC package and is designed for reliable data retention in embedded systems.

Why Choose This Part

This device offers a very low standby current of only 1 uA, making it ideal for battery-powered applications. It supports a high-speed 16 MHz SPI clock for fast data throughput and features a flexible 1.8V to 5.5V supply range, ensuring compatibility with both low-voltage logic and standard 5V systems.

Applications

Microcontroller Configuration Storage
Storing boot parameters, network settings, and calibration constants that must persist across power cycles.
Event Logging
Recording system logs, error codes, or sensor data history in industrial monitoring equipment.
User Preference Retention
Saving user-defined profiles and interface settings in consumer electronics and small appliances.
Firmware Rollback Images
Providing a small, reliable storage area for backup firmware headers or patch metadata.

Getting Started

To integrate this EEPROM, connect the SPI lines (SCK, MOSI, MISO, and CS) to your microcontroller and ensure the WP and HOLD pins are tied high if not in use. Developers can use standard SPI libraries available in frameworks like STM32Cube or Arduino to perform byte-level or page-level writes. Always verify the status register WIP (Write In Progress) bit before initiating subsequent write operations.
