The UPD301B/C is a stand-alone, small form factor USB Type-C™ Power Delivery (PD) Port Controller compliant with the USB Type-C™ Power Delivery 3.0 Specification. The UPD301B/C provides stand-alone operation for a wide range of PD applications, enabling cable plug orientation and detection for a USB Type-C receptacle, and implementing baseband communication with a partner USB Type-C device via the integrated USB Power Delivery 3.0 MAC.

The UPD301B/C is an integrated PD solution with the functionality of a SAMD20 (32-bit ARM Cortex-M0+) microcontroller and a UPD350 PD MAC/PHY. Optionally, a second, third, or fourth PD port is supported via SPI connection of additional external Microchip UPD350 devices. The embedded 32-bit ARM Cortex-M0+ executes the Microchip USB Power Delivery Framework (PSF) Power Delivery stack. A Quick Start Guide and User Manual are also located on the below page. The UPD301B/C devices are shipped blank and require programming with compiled application specific code before operation. Programming is supported by Microchip's industry standard MPLAB X IDE programming environment.

Microchip PSF is available at the Microchip GitHub location https://github.com/MicrochipTech/usb-pd-software-framework.git .

The PSF firmware stack allows for a wide range of USB Power Delivery applications, including but not limited to: Single or Multi-Port Source Only applications, Bus-Powered Sink applications, Battery-Powered Sink applications, and Dual Role Data / Dual Role Power applications such as PD-based docking stations or PD-based dongles. The PSF firmware stack is a continuously deployed open source stack. Not all features that are able to be supported by the UPD301B/C device are necessarily supported by PSF. The supported features may be expanded over time. Refer to the UPD301B/C product page and PSF Online code repository for details on the currently supported feature set and future development road-map. Additional feature development or status of basic feature development may be requested through Microchip support channels.

By integrating the PD firmware and many of the analog discrete components required for USB Type-C PD applications, the UPD301B/C provides a flexible, stand-alone, PD solution for designers who wish to integrate the PD operation with a system controller, implement a custom power supply circuit, support unique PDOs or charging algorithms, or simply control their own PD code.
