TI has announced the preview of the MSP430FR58xx and MSP430FR59xx family of ultra-low-power microcontrollers. This group consists of several devices featuring embedded FRAM nonvolatile memory, an ultra-low-power 16-bit MSP430 CPU, and different sets of peripherals targeted for various applications. The architecture, FRAM, and peripherals, combined with seven low-power modes, are optimized to achieve extended battery life in portable and wireless sensing applications. FRAM is a new nonvolatile memory that combines the speed, flexibility, and endurance of SRAM with the stability and reliability of flash, all at lower total power consumption.
The MSP430FR59xx devices provide an 256-bit AES security encryption and decryption coprocessor.
MSP430FR58xx devices do not provide AES encryption and decryption in hardware.
