Ultra-low-power Read/Write With Increased Throughput

MSP430 devices with embedded FRAM are cutting the industry’s best active power consumption by half, achieving sub-100μA/MHz. Read and writes require just 1.5V, so it is able to operate without a charge pump, unlike Flash and EEPROM. This lowers power and minimizes physical footprint.

FRAM consumes 250x less power than Flash-based devices when running at equal speed (12kB/s)

True Unified Memory

FRAM is uniquely flexible offering developers the ability to use the same memory block to function as program memory or data memory. With FRAM, developers can dynamically partition the memory depending on the current stage of the user’s development cycle. This feature allows faster time to market and simplified inventory control – one single device can be dynamically configured into various memory configurations.

FRAM’s unified memory block can be dynamically configured as program, data or info memory providing unmatched flexibility.

Industry-Leading Read/Write Speeds

In addition to lower power performance, FRAM can also maintain unmatched data throughput. MSP430 with embedded FRAM is capable of 50ns access times, enabling speeds up to 1400 kB/s. With FRAM, embedded memory is no longer the bottle neck of your application.

FRAM can write more than 100x faster than flash, while consuming less power!
