Connectivity and peripherals — what's on the silicon
The MK22DN512VMC5: The peripheral set includes USB OTG, I²C, SPI, UART/USART, and IrDA — enough to talk to a touchscreen, an external ADC, and a fieldbus gateway without glue logic. The 20-channel 16-bit A/D converter (A/D 20x16b) and single 12-bit D/A (D/A 1x12b) cover analog front-end tasks like current sensing or setpoint generation. DMA, I²S, LVD, POR, PWM, and WDT round out the on-chip resources, so the design can offload data movement and keep the CPU on control loops.
Lifecycle and sourcing posture
The MK22DN512VMC5 carries an Active product status — no last-time-buy or phase-out notice on record. That means you can freeze the BOM line for a multi-year production run without an urgent requalification. For supply resilience, the Kinetis K20 family has several Flash-density and package variants; if this exact BGA footprint becomes constrained, a pin-compatible sibling in the same family could be qualified as a second source. Availability and current pricing are confirmed at quote time through independent distribution.
