Adafruit SPI FRAM Breakout – 4Mbit (MB85RS4MT)

Description

The Adafruit SPI Non-Volatile FRAM Breakout featuring the MB85RS4MT chip provides a robust and efficient memory solution for modern embedded systems. Leveraging Ferroelectric RAM (FRAM) technology, this breakout offers 4 Megabits (512 KBytes) of storage that combines the speed of SRAM with the non-volatility of Flash/EEPROM, all without the wear leveling concerns of traditional non-volatile memory. Its rapid read/write capabilities and virtually unlimited write cycles make it ideal for applications demanding frequent data updates and reliable data persistence across power cycles.

This breakout board is engineered for easy integration, featuring an SPI interface that can achieve clock rates up to 40 MHz. It includes essential onboard logic level shifting and a 3.3V regulator, enabling seamless compatibility with both 3V and 5V microcontrollers and development boards. Whether for critical data logging, configuration storage, or real-time data buffering, the Adafruit FRAM breakout ensures data integrity and high performance, making it an indispensable component for makers, engineers, and developers building resilient and power-efficient embedded systems.
