MSP430FR5738 Ultra-low Power MCU

Texas Instruments's MSP430FR5738 is an ultra-low power microcontroller consisting of multiple devices featuring embedded FRAM nonvolatile memory, ultra-low power 16-bit MSP430 CPU, and additional 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. Peripherals include 10-bit A/D converter, 16-channel comparator with voltage reference generation and hysteresis capabilities, three enhanced serial channels capable of I²C, SPI, or UART protocols, internal DMA, hardware multiplier, real-time clock, five 16-bit timers, and more.
