25MHz 16-bit core with 64KB flash — where this MCU fits
The MSP430F5217IYFFT is a 16-bit MCU from TI's MSP430F5xx family, running the MSP430 CPUXV2 core at 25MHz. It carries 64KB of flash program memory and 8KB of RAM — enough for moderate firmware stacks and data buffering in sensor fusion or control-loop applications.
Supply rail and temperature — board-fit parameters
Operates from 1.8V to 3.6V supply, suiting single-cell Li-ion or regulated 3.3V rails. The 64-DSBGA package (0.5mm pitch ball grid array) requires a 4-layer PCB for fan-out and a controlled reflow profile per the JEDEC MSL level on the reel label. The 31 available I/O lines include shared-function pins for the internal oscillator and peripheral interfaces.
On-chip peripherals and connectivity — BOM consolidation
Integrated brown-out detect, POR, DMA controller, PWM timer, and watchdog timer reduce external supervisor and timing ICs. The connectivity set — I²C, SPI, UART/USART, and IrDA — covers common serial bus requirements for sensor hubs and industrial interfaces.
Obsolete — sourcing reality for this MSP430F5xx MCU
Texas Instruments has marked the MSP430F5217IYFFT as obsolete.
