The MSP430G2433IRHB32T: The 32-VFQFN package with exposed pad (5x5 mm body) keeps the footprint small for space-constrained boards.
This part packs 24 general-purpose I/O lines plus a 10-bit ADC with 8 channels — enough to read a handful of analog sensors without an external converter.
A functional alternative is the TI F280041PZQR, a 32-bit C2000 Piccolo MCU running at 100 MHz with 12-bit ADC and CANbus — but it is a different architecture (C28x) and requires a different toolchain and supply voltage (1.14 V core). It is not a pin-compatible swap; the MSP430G2xx family includes pin-compatible density variants within the same series.
