6.1 Overview

The TI MSP430FR697x and MSP430FR692x families of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals. The architecture, combined with seven low-power modes, is optimized to achieve extended battery life for example in portable measurement applications. The devices features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.

The MSP430FR697x devices are microcontroller configurations with up to five 16-bit timers, Comparator, eUSCIs that support UART, SPI, and I²C, a hardware multiplier, an AES accelerator, DMA, an RTC module with alarm capabilities, up to 83 I/O pins, a high-performance 12-bit ADC, and an LCD module with contrast control for displays with up to 320 segments (8-mux).

The MSP430FR692x devices are microcontroller configurations with up to five 16-bit timers, Comparator, eUSCIs that support UART, SPI, and I²C, a hardware multiplier, an AES accelerator, DMA, an RTC module with alarm capabilities, up to 52 I/O pins, a high-performance 12-bit ADC, and an LCD module with contrast control for displays with up to 116 segments (4-mux).
