The 25 MHz clock is enough to run PID loops, Modbus polling, or simple FFTs without waiting for the core. Flash wait states need to be set correctly when crossing the 8 MHz boundary — the CPUXV2 pipeline stalls otherwise. The internal oscillator is factory-calibrated, but for a precise baud rate on UART, an external crystal is still the safer call. 32 KB of Flash is the program store; 2K x 8 of RAM is the working scratchpad. That RAM footprint covers a modest RTOS heap (say, FreeRTOS with a few tasks), but leaves little room for large data buffers. If the design needs a 1 KB Ethernet frame buffer or a 4 KB display frame, this part will run out of RAM — consider the MSP430F5xx parts with 4 KB or 8 KB RAM instead. The Flash endurance is 100k write/erase cycles per sector, which is fine for firmware updates over the product life, but wear-leveling in the bootloader is still good practice. ## 40-WQFN package — layout checklist MSP430F5172IRSBR carries an active product status.","metaTitle":"MSP430F5172IRSBR 16-bit MCU, 25 MHz, 32 KB Flash, 40-WQFN","metaDescription":"Texas Instruments MSP430F5172IRSBR 16-bit MCU, 25 MHz, 32 KB Flash, 2K x 8 RAM, -40°C to 85°C, active lifecycle, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F5xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"31","Core Processor":"MSP430 CPUXV2","Package / Case":"40-WFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 11x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5172","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"40-WQFN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a3cb4d9178f099b2d340a21c97fb61cb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F5172IRSBR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430F5172IRSBR available via RFQ confirmation and available for immediate purchase?","answer":"MSP430F5172IRSBR is available to order through independent distribution.
