The internal oscillator keeps the BOM simple; no external crystal is required for basic timing. On-chip peripherals include a brown-out detect/reset, DMA, POR, PWM, and a watchdog timer. The DMA engine moves data between peripherals and memory without CPU intervention, which matters when the 25 MHz core is busy with the main loop. ## Industrial temperature and package The 40-WQFN package (5x5 mm) with exposed pad keeps thermal resistance low — the pad should be soldered to a copper pour on the PCB for heat sinking. Surface-mount only, supplied in tape and reel or cut tape. The 0.5 mm pitch WQFN needs a decent solder stencil and a reflow profile that matches the package's moisture sensitivity level — standard for this class. No official successor or pin-compatible replacement has been announced.","metaTitle":"Texas Instruments MSP430F5151IRSBR MCU, 25 MHz, 16-bit","metaDescription":"Texas Instruments MSP430F5151IRSBR 16-bit MCU, 25 MHz, 16 KB Flash, 2 KB RAM, -40 to 85 °C, 40-WQFN.
