RT1715 Type-C Port Controller Evaluation Board

EVB_RT1715WSC

Share

The RT1715 is a USB Type-C controller that complies with the latest USB Type-C and PD standards. The RT1715 integrates a complete Type-C Transceiver including the Rp and Rd resistors. It does the USB Type-C detection including attach and orientation. The RT1715 integrates the physical layer of the USB BMC power delivery protocol to allow up to 100W of power and role swap. The BMC PD block enables full support for alternative interfaces of the Type-C specification.

Purpose

The RT1715 is a USB Type-C controller that complies with the latest USB Type-C and PD standards. This document explains the function and use of the RT1715 evaluation board (EVB), and provides information to enable operation, modification of the evaluation board and circuit to suit individual requirements.

Carefully inspect all the components used in the EVB according to the following Bill of Materials table, and then make sure all the components are undamaged and correctly installed. If there is any missing or damaged component, which may occur during transportation, please contact our distributors or e-mail us at evb_service@richtek.com.



Test Points

The EVB is provided with the test points and pin names listed in the table below.

Test point/

Pin name

Signal

Comment (expected waveforms or voltage levels on test points)

VBUS

Voltage

5V as RT1715 is souorce. 5V to 20V as the RT1715 is sink.

CC1

Configuration channel 1

CC1 is used to establish and manage the Source-to-Sink connection.

CC2

Configuration channel 2

CC2 is used to establish and manage the Source-to-Sink connection.

GND

Ground

Ground.

SinkVBUS

Sink voltage

As the RT1715 is sink, sink path will turn on. The RT1715 will get power from port partner for system applications.

GPIO1 to GPIO 4

General purpose I/O 1 to 4

These four pins are used to control other functions in system for user.

UTX, URX

Signal for log

These two pins are used to trace log of Micron.

SDA, SCL

I2C signal

These two pins are I2C communication between the RT1715 and Micron.

ICPDA, ICPCK

Signal for programming

These two pins are used to program Micron.



Operations

The RT1715 supports DRP and Dead battery mode in this evaluation board. The followings explain the functions.

1. Insert 12V adapter and turn on the toggle switch. The 5V, Vadapter, and +3V3_DVDD LEDs wll light up. CC1 and CC2 will start DRP toggling.

2. If the RT1715 is attached as source, ie CC is presented as Rp, source path will be on and output 5V at VBUS.

Pressing “PowerRoleSwap” button will execute power role swap. If sink side accepts, source path will be off, the RT1715 will swap to sink, sink path will be on, and there will be 5V at SinkVBUS.

After the RT1715 swaps to sink, pressing “SinkPDO” button will ask next PDO (PD_Object) from port partner.

3. If the RT1715 is attached as sink, ie CC is presented as Rd, sink path will be on and there will be 5V at SinkVBUS.

Pressing “SinkPDO” button will ask next PDO (PD_Object) from port partner.

Pressing “PowerRoleSwap” button will execute power role swap. If source side accepts, sink path will be off, the RT1715 will swap to source, source path will be on, and there will be 5V at VBUS.

4. If 12V adapter is not inserted, CC1 and CC2 will present Rd. If source is inserted into Type C receptacle, the whole EVB will be active. The sink path will be on and there will be 5V at SinkVBUS.

Pressing “SinkPDO” button will ask next PDO (PD_Object) from port partner.

Pressing “PowerRoleSwap” button will not execute power role swap because there is no adapter power.

5. Pressing “Reset” button will reset +3V3_DVDD. Micron and the RT1715 will be reseted.
