The MSP430FG4619IPZR: The 8 MHz clock is the maximum CPU speed for this MSP430x4xx device. For a 16-bit RISC core, that translates to roughly 8 MIPS. It is adequate for sensor polling, data logging, and control loops with moderate update rates, but not for high-speed digital signal processing or video. The 4 KB RAM limits buffer depth for bursty ADC captures or communication packets.
Package and pinout
The 100-LQFP package measures 14x14 mm. It has 80 I/O lines and includes analog inputs for the ADC and DAC outputs.
