The MSP430FG4617IPZ: It runs at 8 MHz and packs 92 KB of Flash program memory plus 8K x 8 of RAM, which is enough for a moderate firmware image with room for field-upgradeable application code. The 80 I/O lines and integrated peripherals — including a 12-bit ADC with 12 channels and a dual 12-bit DAC — mean this chip can handle mixed-signal control tasks like sensor acquisition and analog output without external converters.
The Brown-out Detect, POR, and WDT peripherals simplify power-up sequencing and watchdog supervision without extra glue logic.
Housed in a 100-LQFP package (14x14 mm body), the device is surface-mount and suited for automated assembly. The 80 I/O lines fan out on a fine-pitch QFP, so the PCB layout needs a via fan-out strategy for the inner rows — typical for this class of package.
TI lists the MSP430FG4617IPZ as Active.
