1.3 Description
The TI MSP430FR572x family of ultra-low-power microcontrollers consists of multiple devices that feature
embedded FRAM nonvolatile memory, ultra-low-power 16-bit MSP430™ CPU, and different peripherals
targeted for various applications. The architecture, FRAM, and peripherals, combined with seven lowpower
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 a 10-bit ADC, a
16-channel comparator with voltage reference generation and hysteresis capabilities, three enhanced
serial channels capable of I2C, SPI, or UART protocols, an internal DMA, a hardware multiplier, an RTC,
five 16-bit timers, and digital I/Os.
