INTRODUCTION

2.1

General Description

The UPD301B/C is a stand-alone, small form factor USB Type-C™ Power Delivery (PD) Port Controller designed to

adhere to the USB Type-C™ Cable and Connector Specification and USB 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 SAMD20 (32-bit ARM Cortex-M0+) microcontroller and UPD350 PD

MAC/PHY functionality. The embedded 32-bit ARM Cortex-M0+ can execute the USB Power Delivery Framework (PSF)

Power Delivery stack. Optionally, a second, third, or fourth PD port is supported via SPI connection of additional external

Microchip UPD350 devices. The UPD301B/C devices are shipped blank and require programming with compiled appli-

cation specific code before operation.

Additionally, the UPD301B/C integrates many of the analog discrete components required for USB Type-C PD applica-

tions, including two VCONN FETs with Rp/Rd switching and current/voltage sense circuitry for over-voltage/current

detection. By integrating the PD firmware and many of the analog discrete components required for USB Type-C PD

applications, the UPD301B/C provides a low cost, stand-alone, fast time-to-market solution for consumer, industrial, and

automotive applications.

The Microchip UPD301B/C family includes the following devices:

• UPD301B

• UPD301C

The UPD301B/C is available in commercial (0°C to +70°C) and industrial/automotive grade 3 (-40°C to +85°C) tempera-

ture ranges. The UPD301B/C is available with dead battery support enabled or disabled in hardware. Device specific

features that do not pertain to the entire UPD301B/C family are called out independently throughout this document.

Table 2-1 provides a summary of the feature differences between family members. For ordering information, refer to the

Product Identification System on page 43.

USB Power Delivery Software Framework

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 continuously deployed. 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. The PSF firmware stack

can be downloaded from the UPD301B/C product page. 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 devel-

opment may be requested through Microchip support channels.
