USER’S GUIDE  2017 Microchip Technology Inc. DS50002679A-page 14 Chapter 2. Getting Started

2.1 CONTENTS OF THE KIT

The EVB-USB4715 evaluation kit includes the basic equipment necessary for evalua- tion. The items included in the kit are: 1. EVB-USB4715 Evaluation Board 2. 12V Power Supply 3. USB cable, A to micro-B

2.2 GETTING STARTED

The Microchip EVB-USB4715 is designed for flexible configuration solutions. It can be configured via default internal register settings, downloadable external firmware to an onboard SPI Flash, through SMBus, or through the onboard configuration switches. Microchip provides a comprehensive software programming tool, MPLAB® Connect, for configuring USB4715 functions, registers, and OTP memory. When configured with the default internal register settings, the device operates as a USB 2.0 hub with 4 USB ports and Microchip’s standard VID/PID/DID settings. For additional information on the MPLAB Connect programming tool, refer to Software Libraries within Microchip USB4715 product page at www.microchip.com/USB4715

2.2.1 Quick Start

To quickly start using the board, perform the following steps: 1. Connect the included 12V power supply to barrel connector on the EVB-USB4715 (J11). 2. Using a USB Type-A plug to USB micro-B plug cable, connect the EVB-USB4715 to a USB host via the upstream “Port 0” USB micro-B socket (J4). 3. You may now connect devices to any of the downstream ports to enumerate and use those devices with the USB host. 4. Connect a shunt to jumper “VBUS_DET” ( J4). 5. Slide the “ON/OFF” switch ( SW2) to “ON”. 6. You can perform additional configuration or evaluate specific features by launch- ing the MPLAB Connect software on your USB host or by manipulating the included hardware configuration options detailed in the next section.

USER’S GUIDE  2017 Microchip Technology Inc. DS50002679A-page 15 Chapter 3. Hardware Configuration

3.1 HARDWARE CONFIG URATION OPTIONS

FIGURE 3-1: EVB-USB4715 REV B (TOP-SIDE)

3.1.1 Configuration

3.1.1.1 EXTERNAL SPI FLASH

Upon power-up, the USB4715 first looks for an external SPI ROM device and a valid signature in the Flash. If one is found, the external ROM is enabled and code execution is initiated from the external SPI ROM device. To select the SPI device, install a shunt to short J18. Install shunts to pins 2-3 and 5-6 of J1. When code is executing from a SPI ROM device, a blue LED (D18) will illuminate. Note: CFG_BC and CFG_Non-Rem options are deselected when a shunt is installed on J1. When operating in SPI mode, all configuration is handled by the code executing from the SPI ROM device. Note: If the SPI Flash is not properly programmed or has an invalid signature, the USB4715 will revert to internal defaults even if the SPI ROM is selected.

EVB-USB4715 Evaluation Kit User’s Guide DS50002679A-page 16  2017 Microchip Technology Inc.

3.1.1.2 SMBUS2

If a SPI Flash device is not found, the firmware checks if SMBus2 is enabled. To select SMBus2 configuration, leave J18 open to disconnect the SPI ROM and select the CONFIG5 option from the CFG_STRAP header by shunting pins 9-10 of J2. Con- nect the SMBus2 pull-up resistors by connecting a shunt to J15 pins 1-2. The SMBus2 signals may be accessed at J14, pins 1 and 3 (pin2 is ground). If CONFIG5 is selected and SMBus2 is enabled (that is, SMBus2 clock and data are pulled up), the USB4715 will wait indefinitely for data from the SMBus2 interface and will not enumerate to the USB host until the special USB_ATTACH command is sent.

3.1.1.3 INTERNAL DEFAULT CONFIGUR ATIONS WITH STRAPPING OPTIONS

When the USB4715 does not detect a valid SPI Flash image or SMBus2 configuration upon power-up, the USB4715 uses internal default register settings. It also sets the Vendor ID, Product ID, Language ID, and Device ID, and additional settings from inter- nal ROM code. If configuration is not done through SPI or SMBus2, additional configuration is available through two hardware straps: CFG_BC_EN and CFG_NON-REM. The controls are configured by selecting one of six resistor values for each pin. The EVB-USB4715 demonstrates two of the six possible resistor values for each of CFG_BC_EN and CFG_NON-REM. These straps are read by the USB4715 device at power-on to deter- mine the default configuration of the device. To select the CFG_BC_EN and CFG_NON-REM modes, shunts must be connected to J20 and J21 headers. To use the battery charging options, connect a shunt to pins 4-5 of J1. For NON_REM options, connect a shunt to pins 1-2 of J1. Select the desired CFG_BC_EN option by connecting a shunt to J20. Select the desired CFG_NON-REM option by connecting a shunt to J21. TABLE 3-1: BATTERY CHARGING OPTIONS (CFG_BC_EN - J20) Shunt Position Configuration 1-2 Ports 1-4 are BC1.2 enabled 2-3 Port 1 is BC1.2 enabled TABLE 3-2: NON-REMOVABLE PORT OPTIONS (CFG_NON-REM - J21) Shunt Position Configuration 1-2 All ports are removable 2-3 Port 1 is non-removable

3.1.2 Power Source - Self Powered

The EVB-USB4715 only supports self-powered operation, and is powered through one +12.0V regulated 'wall wart' external power supply. The power supply plugs into the 2.5 mm connector J11 on the board. Alternatively, an external voltage can be supplied to the screw terminal TERM_BLOCK_2P (J12). The +12.0V feeds a 10A regulator which outputs +5.2V to devices on the board and also supplies the +3.3V regulator.

3.1.3 Downstream Port Power Control

USB power to the four downstream ports is controlled via port power controllers with auto-discharge function. The two downstream Type-C ports are capable of up to 3A of USB Type-C battery charging. Downstream port 1 is configured for 3A charging by default. The two down- stream USB Type-A ports are capable of up to 2.1A of USB battery charging.

3.1.4 USB Type-C Ports

The EVB-USB4715 has two Type-C ports. These are USB 2.0 HS ports. The USB Type-C ports utilize the Microchip UPD360 Type-C port controller in order to detect USB Type-C attachment and plug orientation. The UPD360 monitors the voltage on the USB Type-C CC wires in order to detect USB Type-C attach events. The downstream ports 1 and 2 use UPD360s configured for 3A operation by default.

3.1.5 LED Indicators on EVB-USB4715

Table 3-3 describes the LED indicators included on the EVB-USB4715. Note: The supplied 12.0V external power supply cannot support simultaneous battery charging on all downstream ports. Use a higher power supply if the required test use case exceeds the power capability of the supply. Failure to heed to this warning could result in damage to the 12.0V external power supply.
