USB Power Delivery Software Framework Evaluation Kit

The USB Power Delivery Software Framework Evaluation Kit is a full-featured hardware development platform for evaluating USB Power Delivery Framework (PSF). This RoHS-compliant development platform uses Microchip’s SAMD20 series micro-controller and UPD350 Type-C™ USB Power Delivery (PD) controller. It also supports Microchip’s PD3.0 compliant UPD301B/C standalone Type-C™ PD controller. Powered by the highly configurable PSF software stack, it helps in easy implementation of up to two Type-C™ USB PD ports in your design and reduces the overall time to market. Each port is capable of handling up to 100 W. The USB Power Delivery Software Framework Evaluation Kit is compliant with the USB 3.1 Gen1/Gen2, USB 2.0 HS, Full-Speed (FS), and Low-Speed (LS) USB signaling.
