MSP430FRxx microcontrollers (MCUs) from the MSP Ultra-Low-Power MCU series are the first to integrate FRAM technology. As the world demands faster and higher performance in every application, new memory technology is needed to enable smarter solutions. FRAM from Texas Instruments (TI) provides unified memory with dynamic partitioning and memory access speeds 100 times faster than flash. This new memory is combined with the low-power DNA of MSP to offer lower energy consumption than ever before!

Is power critical to your application? MSP microcontrollers offer the lowest power-consumption in the industry, but you no longer need to take our word for it. The new ULPBench™ benchmark from the Embedded Microprocessor Benchmark Consortium (EEMBC) offers a new way to compare microcontrollers based on application-level power efficiency.
