Chapter 2. Getting Started

2.1 HARDWARE DESCRIPTION

The EVB-USB4624BCUH can be connected to either a USB 2.0 or HSIC upstream host. When using a USB 2.0 host, a standard USB cable must be inserted into the J39 USB style B connector. The VBUS_DET Select switch (SW2) should be set to "External" position and the green "External" LED (D11) is turned on. Once the USB host is attached, VBUS will be detected and the blue VBUS_DET LED (D4) lights up.

When using an HSIC host, the provided U.FL coaxial cables should be inserted onto the J27 (DATA) and J29 (STROBE) connectors. The VBUS_DET Select switch can then be set to either "External" or "Manual" position. When in "Manual" position, VBUS_DET is pulled high to +3.3 VDC and the yellow "Manual" LED (D8) lights up. When the SW2 is in "External" position, the green "External" LED (D11) lights up and an external VBUS_DET port control signal from the host must be wired to the "External VBUS_DET" pin of J21. This signal will let the USB4624 know when an HSIC upstream host is ready to attach. Also, when using an HSIC host, the USB 2.0 upstream port signals must be disabled by jumpering the J34 and J35 headers, thereby pulling the USB DP and DM signals high. Additionally, the J30 header must be jumpered to drive +1.2 VDC onto the VDD12P0 pin of the USB4624.

When removing the U.FL coaxial cables from the evaluation board for any reason, an HSIC Extraction tool must be properly used. See Figure 2-1 for the recommended use of this extraction tool per the Hirose data sheet on proper use of U.FL plugs.

FIGURE 2-1: U.FL COAXIAL CABLE EXTRACTION GUIDELINES

Usage Precautions

1. Plugs

(1) Mating/Unmating

1) To disconnect the connectors, insert the end portion of U.FL-LP-N-2 under the connector flanges and pull off vertically, in the direction of the connector mating axis. 2) To mate the connectors, the mating axes of both connectors must be aligned. The "click" confirms a fully-mated connection. Do not attempt to insert on an extreme angle.

(2) Pull forces on the cable after the connectors are mated. Do not apply a load to the cable in excess of the values indicated in the diagram below.

U.FL-LP Cable Assembly U.FL-R-SMT-1 1N max (U.FL-LP(V)-040, U.FL-LP-062) 2N max (U.FL-LP-040, U.FL-LP-066, U.FL-LP-088) 3N max (U.FL-LP(V)-040, U.FL-LP-062) 4N max (U.FL-LP-040, U.FL-LP-066, U.FL-LP-088) 1N max (U.FL-LP(V)-040, U.FL-LP-062) 2N max (U.FL-LP-040, U.FL-LP-066, U.FL-LP-088)

(3) Precautions
Do NOT forcefully twist or deform wires.

The downstream ports of the EVB-USB4624BCUH are numbered 1 through 4. Downstream ports 1 and 2 are HSIC ports, while downstream port 3 and port 4 are USB 2.0 ports. The USB4624 allows downstream port 3 and/or port 4 to be configured for high current battery USB charging. Power to downstream port 3 and port 4 is controlled through the MAX1562H devices, U4 and U6. Each device provides up to 4A to the corresponding downstream port. These port power controllers have their own power source "5V_USB" which is generated from the U12 +5 VDC switching regulator. This allows a maximum of 3A consumption per port power controller when both USB 2.0 downstream ports are configured for battery charging. The U4 and U6 port power controllers are currently set for a current limit of 2.97 Amps. Power enabling and

overcurrent sensing on downstream port 3 and port 4 is achieved via the PRTPWR3 and PRTPWR4 pins of the USB4624 respectively. The HSIC Enable pins for downstream port 1 and port 2 can be driven by using the HSIC support header J32.

Four female headers (J2, J9, J3, and J10) are also available so that the user can attach a meter and display the current draw at each downstream USB 2.0 port. Please refer to the EVB-USB4624BCUH schematics and Bill of Materials (BOM) for details on these meter devices. Through the MAX232E device, (U15), a UART RS232 interface is provided. The RS232 transmit and receive signals can be accessed via the serial header J37.

The EVB-USB4624BCUH is designed to allow flexible configuration options. It can be configured with default internal register settings, through an SMBus or through a downloadable external firmware to an SPI Flash device. It supports "Quad-Page" configuration OTP flash (four consecutive 200 byte configuration pages). The following sections detail the various configuration methods and features. Note that there are optional footprints available on this evaluation board to support alternate circuitry not discussed in this user manual.

2.2 USB4624 CONFIGURATION

Default: Upon power-up, the USB4624 searches for an external SPI Flash device that contains a valid signature of "2DFU" beginning at address 0xFFFA. If an SPI device is not present, the firmware checks to see whether SMBus is enabled. If the SMBus is disabled, the USB4624 attempts to load the configuration from an external I²C™ EEPROM. If no external options are detected, the USB4624 will operate using the internal default register settings. It also sets the vendor ID, product ID, language ID, device ID and additional settings from internal ROM code.

SPI Flash Option: If upon power-up, an external SPI Flash device is present, the external ROM is enabled and code execution is initiated from the external SPI device. The SPI Flash device (U17) on the EVB-USB4624BCUH is populated by default. To hold this device in reset and disable the SPI device for any reason, the J33 "SPI Hold" header can be shorted together thereby tying the "HOLD" signal low.

SMBus Option: The SMBus interface is disabled by default via the 10 kOhm pull down resistor on SM_CLK. To enable SMBus, the SM_CLK pin must be pulled high to +3.3 VDC with a strong pull up resistor. This is often embedded within the external SMBus tool (not included) when inserted onto the J1 System Management Port header. All device configuration must be performed via the ProTouch programming tool. For more information on this tool, contact your local sales representative. When SMBus is enabled, the firmware configures the GPIOs to act as an SMBus slave. As an SMBus slave, the firmware waits indefinitely for the SMBus configuration.

2.3 CLOCK SOURCE - 24 MHz CRYSTAL

By default, a 2 mm x 1.6 mm Murata 24 MHz crystal, Y1, is populated on the evaluation board as the clock source for the USB4624.

2.4 POWER SOURCE AND RESET – SELF-POWERED

The EVB-USB4624BCUH only supports self-powered operation, and is powered by one +12 VDC regulated external DC power supply. A +12V input is needed to provide enough current to the downstream ports in battery charging modes. The +12V external DC power supply plugs into the on board 2.5 mm connector J36. Alternatively, an external voltage can be injected onto the external 12V header, J31, which is not populated by default. The +12V feeds two +5 VDC switching regulator modules U12 and U14. The U12 6 Amp regulator generates "5V_USB" to the two port power

controllers for the downstream USB 2.0 ports. This allows each downstream port to consume up to 3 Amps when in battery charging mode. The U14 2 Amp regulator generates "5V" to other miscellaneous circuitry across the evaluation board. The output of the U14 regulator controls the on board +3.3V and +1.2V regulators.

Power to the USB4624 is controlled by the J11, J16, J18, and J19 power headers. These headers are configured by default for an external +3.3V and +1.2V power supply, bypassing the USB4624's internal regulators. For alternative power options, please refer to the USB4624 data sheet.

A voltage supervisor circuit is used to provide a system RESET# to the USB4624. The Microchip device TC1270A (U2) asserts RESET# to the DUT on power up and release it after +3.3V is stable on the USB4624. This on board reset device also monitors any short power off conditions that might occur in the system. If 3V3 falls below +3.08V, the device asserts RESET# to the DUT for a defined period until 3V3 has increased above this voltage trip point. A reset can also be generated to the DUT by pressing the reset switch SW1 or by supplying an external reset via the Reset header J4.

2.5 LEDs AND CONNECTORS

The functions of all the on board LEDs and headers are described on the following sections.

2.5.1 Powered and Suspend State LEDs

Chapter 3. Battery Charging Support

3.1 INTRODUCTION

The EVB-USB4624BCUH supports several different Battery Charging modes, providing an array of flexible configuration solutions. Both downstream port 1 and port 2 can be separately configured for battery charging via OTP, downloadable external firmware to an on board SPI Flash or through SMBus commands. Each port's configuration is independent of the other ports.

The battery charging mechanism automatically switches ports between states that perform the BC1.2 CDP handshake (which allows full USB communication with a USB host while charging), and states that emulate the dedicated chargers from charging device vendors. This allows support for the BC1.2 CDP mode and emulation of dedicated chargers in DCP mode, without interfering with normal USB operation of any USB 2.0 device attached to the port. Battery charging is supported through the use of standard port power controllers.

Section 3.2 “Charging Port Roles” describes the modes of operation. For more information on battery charging, please refer to the Application Note 34.5 and the USB Battery Charging 1.2 specifications.

3.2 CHARGING PORT ROLES

The EVB-USB4624BCUH's battery charging enabled downstream ports automatically switch between various roles depending on the USB state of the EVB-USB4624BCUH. These roles are:

1. BC1.2 charging downstream port (CDP - 1.5A with data)
2. Standard downstream port (SDP - 0.5A with data)
3. Dedicated charger emulation port (DCP - power brick without data)
4. Custom profiles loaded via SMBus or OTP

When switching between roles, the EVB-USB4624BCUH toggles power to the attached device if appropriate. The power toggle occurs if charger or USB renegotiation is necessary based on the following conditions:

1. If the port is in an SDP role while the hub is disconnected from the host, the port toggles power when switching to a DCP role to allow the downstream device to negotiate with the DCP mechanism.
2. If the port is in a DCP role and the port needs to switch to a CDP or an SDP role, the port toggles power to allow the device to renegotiate with a CDP handshake and/or USB attach.

When battery charging is disabled for a EVB-USB4624BCUH port, the port acts as a normal USB hub port.

When the EVB-USB4624BCUH's upstream port is connected to a USB host and the EVB-USB4624BCUH is not in USB 2.0 suspend and/or USB 2.0 remote wake is enabled, battery charging enabled ports follow the BC1.2 specification for CDPs. In this case, after a USB 2.0 device is attached, the port behaves as an SDP until the device is detached from the hub or the hub is detached from the host.

When a USB port is in a state in which device-host USB communication is not possible, a battery charging enabled port is not required to act as a USB hub port and is therefore free to enter states that emulate dedicated chargers. For the EVB-USB4624BCUH, there are two cases where this applies:

1. The EVB-USB4624BCUH upstream port is not connected to a USB host.
2. The EVB-USB4624BCUH is in USB suspend with remote wake on the USB 2.0 portion of the EVB-USB4624BCUH disabled and no USB 2.0 device connected as a USB device on the downstream port. If USB 2.0 remote wake is disabled, the hub cannot generate resume signaling and does not need to detect a USB 2.0 attach.

In case 2, the EVB-USB4624BCUH's charging ports do not enter dedicated charging states when there is a USB 2.0 device attached as a USB device. There are two reasons for this behavior:

1. Entering dedicated charging states may involve changing the state of an attached device due to power toggling and/or USB linestate changing. Because the host system is unaware of the battery charging mechanism of the EVB-USB4624BCUH, the host could find the device in an unexpected state when exiting suspend.
2. The attached device will not be able to signal resume signaling to the host when the port is in a dedicated charging state. Hubs must propagate resume signaling from downstream devices even when remote wake generation is disabled for the hub.

If the EVB-USB4624BCUH is in USB 2.0 suspend with USB 2.0 remote wake disabled and a USB-attached device is removed from a port, the port switches to the DCP role because possible resume propagation is no longer required.

3.2.1 BC1.2 Charging Downstream Port (CDP) Description

Devices that do not follow the BC1.2 CDP specification behave as they normally would when inserted into a standard USB port. The EVB-USB4624BCUH ports in CDP mode allow normal USB operation/communication between normal devices and USB hosts by switching to the SDP role after downstream device detection and absence of a BC1.2 CDP handshake from the device. When a subsequent device detach is detected, the port switches back to the CDP role.

Devices that follow the BC1.2 CDP specification are also allowed to communicate normally with the USB host when inserted into the EVB-USB4624BCUH ports in CDP mode. Additionally, prior to allowing the normal USB connection between the host and the BC1.2 device, the EVB-USB4624BCUH port performs the BC1.2 CDP handshake to inform the BC1.2-compliant device that it may draw current exceeding the USB specified limits. When the handshake is complete, the port switches to the SDP role to allow USB functionality for the device. When a subsequent device detach is detected, the port switches back to the CDP role.

3.2.2 Standard Downstream Port (SDP) Description

When a port is in the SDP role, it behaves as a normal hub port and allow full USB functionality for an attached downstream device.

3.2.3 Dedicated Charger Emulation Port (DCP) Description

The advantage of the EVB-USB4624BCUH dedicated charger emulation port over the BC1.2-specified DCP is that it supports BC1.2 compliant charging devices and many non-BC1.2 compliant charging devices. The following paragraphs describe the

EVB-USB4624BCUH modes of operation when its downstream ports are in dedicated charging states (when normal USB connection is not required as described in previous sections).

Dynamic Mode:

The EVB-USB4624BCUH can be configured to dynamically react to devices inserted into the downstream ports and emulate the appropriate type of charger for the inserted device. In this configuration, the port begins in Apple ^® charger emulation mode and switches to China Charging, Blackberry ^® or BC1.2 device charger emulation when such devices are detected by the port. When a device is detached, the port starts again in Apple charger emulation mode.

Configurable 1A and 2A Apple modes are available depending on the capabilities of each port's port power controller.

An EVB-USB4624BCUH port with a standard port power controller also supports Samsung ^® Galaxy Tab ^™ charger emulation in addition to the above modes.

Static Mode:

The EVB-USB4624BCUH can be configured to keep the downstream ports in a fixed charger emulation state. Currently, Apple and Samsung Galaxy Tab or China Charging fixed charger emulation modes are available.
