EZAUGARRI BEREZIAK
The Hub Feature Controller
The Hub Feature Controller is an embedded device internal the to hub used to handle many special features. These include runtime register read and write, handling FlexConnect commands, bridging features, and OTP memory pro-gramming and reading.
The Hub Feature Controller uses a generic USB device class controllable through the WinUSB driver on Windows® an dlibusb on Linux®.
The USB5734 always enables the Hub Feature Controller by default (end-system integrators can optionally disable it).
The USB5744 and USB5742 devices have ordering options for Hub Feature Controller to be enabled or disabled by default. These part numbers end in “X01.” (See Table 2.)
Bridging Features
Bridging features allow a USB host to interface with embedded devices through the hub device. The USB host communicates to the internal Hub Feature Controller device embedded inside the USB hub to send or receive data through on e of the bridge interfaces.
The bridge interfaces supported are:
- GPIO
- SPI of up to 60 MHz
- I2C/SMBus of up to 400 kHz
- UART of up to 115.2 kHz
Some of the bridging features can be used in parallel together, while others are mutually exclusive. Consult the specific USB57xx device data sheet for details.
The GPIO, SPI, I2C/SMBus, and UART use the generic USB device class, which is controllable through the WinUSB driver on Windows and libusb on Linux.
End-system integrators are required to write their own end applications to make use of the bridging features. Microchi p provides two software resources to make the software development easy:
- Windows-only: MPLAB® Connect Configurator
MPLAB Connect® Configurator includes a GUI for quickly trying out bridging features. A DLL package is also included for controlling the bridging features from your own application. - Linux-only: Linux Application Code Examples
This package includes numerous exampUSB gailuak kontrolatzeko libusb Linux liburutegi estandarra erabiltzen duten aplikazioak. Kode hau erreferentzia gisa erabil daiteke zure aplikazioak diseinatzeko.
FlexConnect (USB5734 Only)
- USB5734 supports FlexConnect of both the USB2 and USB3 communication channels with downstream port 1.
- FlexConnect can be controlled via a USB command to the Hub Feature Controller device using direct FlexConnect register manipulation through I2C/SMBus or by GPIO control. GPIO requires configuration to be set to ‘Configuration 2 – FlexConnect Mode’ via the CFG_STRAP hard strapping pin. Only one control method should be used at a time to avoid control conflicts leading to non-deterministic behavior.
- FlexConnect requires careful design choices since there is no standard use case for this feature. A common way to use the feature is to allow two different hosts to alternatively control the USB hub and all downstream devices. Only one hu b can control the hub and device tree at a time, and the full device tree must be fully re-enabled each time host control is haded off.
- Another implementation involves “swapping” a host-device relationship wherein the original USB host to the USB57xx becomes a device, and a component which was operating as a device switches to Host mode. This requires careful consideration to properly control three separate system components during role changes.
- Ohiko arazoen artean, erabili beharreko konektore eta kableen zehaztapena dago. Adibidez,ample, when a Type-A port is used on a downstream port and FlexConnect is enabled for that downstream port, connecting a new host to that “Flex Port” requires a non-standard Type-A-to-Type-A cable. In addition, there could be VBUS back-drive problems (and the potential to trigger overcurrent alerts) if both ends of the cable supply 5V VBUS.
- Supporting FlexConnect with USB Type-C ports can be exceptionally challenging as Type-C VBUS, VCONN, and CC control must be well thought out and managed appropriately to ensure reliable connections can be made while flexed.
- Refer to AN4767 – USB5734 FlexConnect Operation for detailed design guidance.
BC1.2 Battery Charging
All USB57xx devices support BC1.2, which is a USB-IF maintained standard for allowing portable devices to charge up to 1.5A from 5V VBUS.
A BC1.2 handshake is always initiated by the portable device. It is achieved through short pulses on the D+ and D–USB2 data lines. The hub downstream port responds accordingly to complete the handshake, depending on which mode of operation the hub port is in.
Dedicated Charging is a charge-only profile and only operates when the USB57xx is not connected to a USB Host.
Charging Downstream Port mode allows for charging and data, and it operates when the USB57xx is connected to a USB host when BC1.2 CDP mode is enabled.
The BC1.2 hardware configuration straps on USB57xx enable both CDP and DCP mode.
KONFIGURAZIOA
Default Factory-Programmed Configurations
USB57xx gailuek konfigurazio-ezaugarri ugari eta hainbat funtzio-pin programagarri dituzte eskuragarri, S/I gaitasun desberdinak ahalbidetzen dituztenak. Gailu bakoitzak konfigurazio-aukera bereziak ditu, CFG_STRAP hardware-pinaren bidez hauta daitezkeenak, eta horrek funtzio-pin programagarrien hautaketa lehenetsiak egiten ditu gailuaren erabilera-kasu esperoenetan oinarrituta. Gailu bakoitzak fabrikan programatutako konfigurazio-ezarpenak ere baditu, eta fabrikan programatutako FW adabakiak ere izan ditzake.
Additional End-System Integrator Configuration
It is expected that end-system integrators will reconfigure the USB57xx to meet their individual system needs. Peripherals and each pin function can be selected individually to customize the solution. Only changes from the default factory preconfigured settings need to be made.
The following methods for end-system-integrator configuration are flexible:
- OTP
- Serial (I2C/SMBus) from embedded serial controller
- Upstream USB host control during runtime
Additionally, a separate firmware image can be executed from an SPI Flash memory device in special cases where custom firmware implementation is needed. Microchip develops all customized firmware images based on special, case-by-case business negotiations. When executing the firmware image from an SPI Flash device, internal OTP memory configuration is ignored. Instead, an equivalent configuration mechanism is also executed through and stored within the SPI Flash memory device.
Configuration details and the device register map located in the AN1903 – Configuration Options for the USB5734, USB5744, and USB5742 are available on the USB57xx product page on Microchip.com

Konfigurazio bakoitzatage aukerakoa da. Oro har, amaierako sistema integratzaileek konfigurazio metodo bakarra hautatzen dute. Geroagoko konfigurazio urratsetan aldatutako edozein ezarpen indibidualak aurreko urratsetan egindako erregistro aldaketak gainidazten ditu. Ikusi 3. taula konfigurazio metodoei buruzko informazio gehiago lortzeko.
TAULA 3: NOTES ON CONFIGURATION METHODS
| Osagaia | Oharrak |
| OTP | The USB57xx devices have 8 kB of OTP configuration memory. The factory-programmed OTP con- figuration load only occupies a small fraction of this total available memory (i.e.: typically <1 kB) to ensure sufficient space is left for end-system integrator use. The end-system integrator can program OTP memory a number of times until the OTP memory is completely filled. Only registers which are specifically manipulated by the OTP configuration are impacted. OTP is loaded sequentially in the order it was programmed, so if the same register(s) are manipulated multiple times, the last sequentially programmed setting(s) will take effect. |
| SPI Flash | Kanpoko SPI Flash bat aukera bat da firmware irudi pertsonalizatua behar duten erabilera kasu berezietarako. Microchipek garatzen ditu firmware irudi pertsonalizatuak sistema integratzaile batekin egindako akordio berezi baten bidez. SPI Flash memoriaren tamaina firmware irudiaren tamainaren beharren araberakoa da, baina 1 MB nahikoa da firmware behar pertsonalizatu gehienentzat. |
| Serieko konfigurazioa | Serial Configuration is enabled through hardware pin strap options. When enabled, the USB57xx device waits indefinitely for the I2C/SMBus or SPI master to configure the device and issue a special command to enter the Runtime phase. The I2C/SMBus or SPI controller will be able to read back any configuration settings already modified by OTP or EEPROM. |

Oharra 1: The VSM Filter allows the Windows host to send vendor-specified commands to the hub endpoint directly. This is typically blocked by Windows OS. The VSM commands to the hub are required for communicating with a Microchip Smart Hub which has its internal Hub Feature Controller device USB endpoint disabled. If MPLAB Connect Configurator detects a Microchip Smart Hub, but the Hub Feature Controller is not present, it will attempt to re-enable the Hub Feature Controller temporarily (while the tool is running) via a VSM command. With the Hub Feature Controller device temporarily enabled, MPLAB Connect Configurator can then carry out the various features supported by the tool (such as programming, register read/write, etc.). Also note that if the VSM command support is internally disabled via the hub configuration (i.e.: previously set in OTP) by an end system integrator, this command will not be successful and the user will not able to read back configuration or program new ones.
USB57xx familiako gailuek USB-IF estandarrak definitutako gailu klaseak erabiltzen dituzte. Horrek esan nahi du ez dela bezeroak edo kontrolatzaile berezirik behar gailua funtzionarazteko.
