INTRODUCTION
General Description
The USB Type-C
TM
Specification was introduced in August 2014 and substantially expands the capabilities of USB. The
key new features include:
• New Connector
- Smaller Form Factor
- 24 Pins
- Reversible Insertion
• Simplified Current Capability Marking
- Resistor-divider implementation instead of DP/DM “handshake”
The Microchip UTC2000 USB Type-C controller targets designers who wish to gain the benefits of the small, reversible
form factor and elevated charging current abilities of a USB Type-C solution while minimally impacting the overall cost
per port.
The UTC2000 USB Type-C controller is a cost-effective, simple solution that facilitates rapid migration of legacy USB
2.0/3.0 designs to the USB Type-C connector. The UTC2000 controller is designed for USB 2.0/3.0 Downstream Facing
Port (DFP) and Upstream Facing Port (UFP) applications and performs all of the necessary detection and control
required for implementing a basic USB Type-C connector. The UTC2000 features ADCs that monitor the CC1 and CC2
pins of the USB Type-C receptacle to detect various connection events.
In a DFP application, passive cables, powered cables, and USB audio adapters can all be detected. Controls for
enabling a USB +5V port power switch, VCONN 5V active cable supply, and audio adapter enable are all included. Addi-
tional features include host enable control and overcurrent detection.
In a UFP application, the UTC2000 detects a valid USB Type-C connection, the plug orientation, and the charging capa-
bility of the DFP. The UTC2000 also monitors VBUS to ensure a valid VBUS range and detected overcurrent.
The UTC2000 can operate from a single 4.5V-5.5V supply and is available in commercial, industrial and extended tem-
perature range options.

Downstream Facing Port (DFP) Implementation Overview
A UTC2000 Implementation of a DFP minimally requires 5 major components/circuitry blocks:
Microchip UTC2000
A USB 2.0 downstream port (USB 3.0/USB 3.1 may optionally be implemented based upon system requirements)
A USB Type-C Receptacle
A 5V Port Power Controller capable of supplying the advertised current capability
(advertised with the value of Rp and the pull-up voltage)
• CC Pin Circuitry:
- Rp Pull-Up Resistors
- VCONN Control/Switching
Note:
A High-Speed or Super Speed USB switch is also recommended but optional. For USB 2.0 applications,
this component may be omitted. For USB 3.0/USB 3.1 applications, this component may only be omitted
if two USB 3.0/USB 3.1 downstream ports are dedicated for use on the USB Type-C port.

Type-C Upstream Facing Port (UFP) Implementation Overview
A UTC2000 Implementation of a UFP minimally requires 4 major components/circuitry blocks:
Microchip UTC2000
A USB 2.0 upstream port (USB 3.0/USB 3.1 may optionally be implemented based upon system requirements)
A USB Type-C Receptacle
CC Pin Circuitry:
- Rd Pull-Up Resistors
Note:
A High-Speed or Super Speed USB switch is also recommended but optional. For USB 2.0 applications,
this component may be omitted. For USB 3.0/USB 3.1 applications, this component may not be omitted
unless a Microchip Hub with FlexConnect is utilized. Refer to the Microchip USB5734 USB Type-C Evalu-
ation Board for details on implementation.
