Adafruit SPI Non-Volatile FRAM Breakout - 2 Mbit / 256 KBytes - MB85RS2MTA

FRAM (Ferroelectric RAM) is a cutting-edge data storage technology that combines the benefits of DRAM speed with non-volatility, allowing for stable data retention without power. This Adafruit SPI Non-Volatile FRAM Breakout features 2 Megabits (256 KBytes) of FRAM storage.

This breakout board interfaces via SPI and supports up to 40 MHz clock speeds. Each byte can be read and written rapidly, with endurance up to 10 trillion (10,000,000,000,000) write cycles and data retention spanning decades.

The board includes 3.3V logic level shifting and regulator, making it compatible with both 3V and 5V systems. Its breadboard-friendly layout includes standard 0.1" headers for easy integration into your projects.

• 2 Megabit (256 KB) FRAM storage
• SPI interface with up to 40 MHz clock rate
• Endurance of 10 trillion write cycles per byte
• Data retention up to 95 years at 55°C
• Low power consumption (2.6mA max at 40MHz)
• Operating temperature range: -40°C to +85°C
• 3.3V logic level shifting and regulator for 3-5V compatibility

This FRAM module is ideal for low-power data logging and systems requiring fast, durable, and stable memory retention without concern for wear leveling.
