Peripherals and connectivity
On-chip peripherals include a brown-out detect, POR, DMA, PWM, and a watchdog timer — all standard for a control-oriented MCU. The connectivity block covers I²C, IrDA, SCI, SPI, and UART/USART, so it can talk to common sensors, ADCs, or a host controller without extra glue. With 31 I/O lines in a 40-pin QFN, most of the package pins are usable for GPIO or alternate functions.
Sourcing and lifecycle
The MSP430F5131IRSBR carries an active product status — no end-of-life notice or last-time-buy window on record. That means it's safe to specify into a new BOM or replenish an existing line without worrying about a forced redesign. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
