The 0.65 mm lead pitch is pick-and-place friendly on a 2-layer board — no via-in-pad required. ## Peripheral set — serial bridge and PWM-ready Connectivity includes I2C, SPI, and UART — enough to interface an external sensor hub, a radio module, or a serial display. The 10-channel 10-bit ADC handles basic analog inputs (potentiometers, thermistors, current shunts) but lacks differential inputs — plan for single-ended signals only. On-chip DMA, PWM, and a watchdog timer reduce external glue logic for timer-driven motor or LED control.","metaTitle":"MSP430F5172IDAR MCU, 25MHz, 32KB Flash, 38-TSSOP","metaDescription":"Texas Instruments MSP430F5172IDAR 16-bit MCU, 25MHz, 32KB flash, 2Kx8 RAM, 38-TSSOP.
