The DSBGA package requires careful solder-paste stencil design and X-ray inspection post-reflow, but the trade-off is a significantly smaller board outline compared to a QFN or TSSOP. The 31 I/O lines are distributed across the ball array, so layout must account for fan-out on a 4-layer PCB to avoid routing congestion. Surface-mount assembly with the Tape & Reel packaging supports high-volume pick-and-place. On-chip peripherals include a brown-out detect/reset (BOR), power-on reset (POR), DMA controller, PWM timers, and a watchdog timer (WDT) — all standard for the MSP430F5xx family. The DMA offloads data transfers from the CPU, which is useful for ADC sampling or UART buffering without stalling the core. Serial connectivity covers I²C, SPI, UART/USART, IrDA, and SCI — enough to interface with most common sensors, radios, and external memory devices. The part is RoHS-compliant as standard for TI's current portfolio.","metaTitle":"MSP430F5171IYFFR 16-bit MCU, 25 MHz, 32 KB Flash, DSBGA-40","metaDescription":"Texas Instruments MSP430F5171IYFFR 16-bit MCU, 25 MHz, 32 KB Flash, 2 KB RAM, 1.8-3.6 V, -40~85°C, DSBGA-40.
