The 14-channel 10-bit ADC covers analog monitoring (thermistors, current shunts, potentiometers) without an external mux, and the peripheral set includes I²C, SPI, UART, LIN, and IrDA, so a single MCU handles sensor bus, actuator interface, and diagnostic link.

Frequently asked questions
Can MSP430FR5721IRHAT replace MSP430FR5720?
The MSP430FR5720 is a lower-density sibling in the same FRAM family. The MSP430FR5721IRHAT offers the same 8 MHz core and peripheral set but with 4 KB FRAM versus 2 KB on the '5720. Pin-compatible in the same 40-VQFN package, so a BOM swap is straightforward if the extra memory is needed.
