The USB OTG block handles on-the-go negotiation for direct peer-to-peer links — useful for field-update dongles or portable instrumentation that talks to a host PC and a thumb drive. DMA, I²S, LVD, POR, PWM, and WDT round out the peripheral set, covering audio streaming, brown-out supervision, and motor PWM without glue logic.
No PCN or EOL notice is on record. For a BOM freeze, this part is still a first-choice entry — no LTB risk for new production runs.
The MK20DN32VMP5 runs at 50 MHz, based on the ARM Cortex-M4 core. That speed is sufficient for real-time control loops and USB OTG throughput without external PHY overhead.
Yes, the MK20DN32VMP5 includes USB OTG (dual-role host/device) along with I²C, SPI, UART/USART, and IrDA. The supply range is 1.71 V to 3.6 V, covering single Li-ion or 1.8 V rails.
