The MSP430F5172IYFFR is a 16-bit MCU from the MSP430F5xx series, running at 25 MHz. It has 32 KB Flash, 2 KB RAM, 31 I/O lines, and connectivity including I²C, SPI, UART/USART, IrDA, and SCI.
The 25 MHz clock rate on the 16-bit core is adequate for control loops and protocol handling at standard UART/SPI speeds. The 2 KB RAM limits buffering for multi-protocol stacks or large data-logging arrays.
The MSP430F5172IYFFR is rated for -40°C to 85°C (TA), covering industrial and outdoor telecom enclosures but not extended automotive or downhole environments.
No pin-compatible drop-in replacement is listed in TI's documentation for this DSBGA-40 package. A functional migration within the MSP430F5xx family would require a PCB layout change due to the fine-pitch BGA footprint.
The full datasheet for the MSP430F5172IYFFR is available from TI under the base product number MSP430F5172. It covers the CPUXV2 core, 25 MHz operation, 32 KB Flash, 2 KB RAM, peripheral set, and electrical characteristics.
