1.3 Description

The TI MSP430FR573x 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.
