The Microchip USB7002 SmartHub is low-power, OEM configurable, USB 3.1 Gen 1 hub controller with 4 downstream ports and advanced features for embedded USB applications. The USB7002 is fully compliant with the Universal Serial Bus Revision 3.1 Specification and USB 2.0 Link Power Management Addendum. The USB7002 supports 5 Gbps Super-Speed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) USB downstream devices on all enabled downstream ports.
A SmartHub is defined as a USB hub that integrates system levels functions typically associated with a separate MCU or processor. The USB7002 SmartHub enables communication to other peripherals in addition to USB. This I/O Bridging capability allows the host to seamlessly interface to peripherals via I2C, SPI or GPIOs over USB. The USB7002 also enable a downstream device to take control of the host system by swapping roles and becoming the host port. The USB7002 can also switch between two different hosts if required. This role changing technology is called FlexConnect and can be initiated through hardware or software commands.
The USB7002 supports native Type-C connectivity on the upstream port and two of the downstream ports. The hub includes internal Type-C CC pin logic and an internal USB 3.1 Gen 1 multiplexer to support both Type-C insertion orientations. The USB7002 also supports the legacy USB speeds (HS/FS/LS) through a dedicated USB 2.0 hub controller that is the culmination of six generations of Microchip hub feature controller design and experience with proven reliability, interoperability, and device compatibility. The SuperSpeed hub controller operates in parallel with the USB 2.0 controller, decoupling the 5 Gbps SS data transfers from bottlenecks due to the slower USB 2.0 traffic.
The USB7002 supports downstream battery charging. The USB7002 integrated battery charger detection circuitry supports the USB-IF Battery Charging (BC1.2) detection method and most Apple devices. The USB7002 provides the battery charging handshake and supports the following USB-IF BC1.2 charging profiles: DCP: Dedicated Charging Port (Power brick with no data); CDP: Charging Downstream Port (1.5A with data); SDP: Standard Downstream Port (0.5A with data); Custom profiles loaded via SPI EEPROM or OTP.
MPLAB Connect Configurator, Microchip’s proprietary software utility, can be used to program On-chip One Time Programmable (OTP) ROM for the USB5806 which stores required register settings to ensure the desired start up configuration at power on. All LED, GPIOs and port control signal pins are under firmware control, allowing for maximum operational flexibility. However, for even more simplicity, the USB7002 can be configured through a series of external low-cost resistor bootstraps. A handful of bootstap pins are available on the USB7002 to enable standard configurations for GPIOs and downstream ports. No OTP programming required..
The USB7002 is also AEC-Q100 certified support traditional data transfer applications that require higher data rates than USB2.0 as well as Multi-Host appliciations like CarPlay and CarLife that enable the graphical user interface of a phone to be displayed on a vehicles' screen within a car.*The USBCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
The EVB-USB7002 is a demonstration and evaluation platform that provides the necessary requirements and interface options for evaluating the USB7002, which is a 4-port High-Speed (HS), Native USB Type-C SmartHub on a 4-layer RoHS-compliant Printed Circuit Board (PCB). This allows the user to gain an understanding of the product and accelerate the integration of the USB7002 into the...
