The MCU packs a brown-out detect/reset, POR, PWM, and WDT on-chip, plus IrDA, SCI, SPI, and UART/USART connectivity through 12 general-purpose I/O.
The MSP430FR2xxx family includes pin-compatible siblings with larger FRAM densities (1 KB, 2 KB) that drop into the same 16-TSSOP footprint without a board change.
The MSP430FR2000IPW16R runs at 16 MHz.
