The MK20DX64VMP5: USB OTG on the connectivity block means this MCU can act as either host or device — useful for field-upgrade dongles or data-logging pendants without an external USB controller. The 13-channel 16-bit ADC gives enough analog front-end for a three-phase current-sense plus auxiliary inputs, all sampled without an external mux.
Industrial temperature range and package constraints
If your assembly line lacks BGA capability, the same die is available in a QFP package on a different order code; verify the pinout before substituting.
