Frequently asked questions
Does the MSP430FE4252IPMR support in-circuit firmware update via BSL, or does it require JTAG programming?
The FE variant supports BSL bootloader programming over the integrated UART/USART port in addition to JTAG and Spy-Bi-Wire (SBW) debug. The MSP430FET debug probe supports SBW. Check the TI SLAU319 BSL documentation for the FE family for the exact pin and command sequence required for field programming.
How many usable digital I/O lines does the MSP430FE4252IPMR have?
The part has 14 I/O total, but these pins also serve as LCD segment drivers when the integrated LCD controller is active. The usable digital I/O count drops when the display is enabled — audit your I/O map against the LCD segment count your application requires before finalising the design.
