Industrial temperature range and deployment environment
Connectivity and peripherals — USB OTG, CAN, and the analog chain
USB OTG support (device and host) is on-chip, so the same MCU can serve as a USB peripheral in a data-logger or as a host for a thumb-drive firmware update. CAN 2.0B is built in — no external transceiver needed on the MCU side for industrial networks. The 42-channel 16-bit ADC and dual 12-bit DAC cover multi-axis analog sensing; the DMA engine can shuttle ADC results to RAM without CPU intervention, keeping the core free for control math.
For BOM planning, the base number MK20DN512 covers the full Flash/RAM density tier; if you need a different package or temperature grade, the family shares the same core and peripheral set.
