描述 Description

The Microchip USB7016 SmartHub? IC is a low-power, OEM configurable, USB3.2 Gen 1 hub controller with?6 downstream ports and advanced features for embedded USB applications. The USB7016 is fully compliant with the Universal Serial Bus Revision 3.2 Specification and USB2.0 Link Power Management Addendum. The USB7016 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 IC is defined as a USB hub that integrates system levels functions typically associated with a separate MCU or processor.?The USB7016 SmartHub IC 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 USB7016 also enable a downstream device to take control of the host system by swapping roles and becoming the host port. The USB7016 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 USB7016 supports native Type-C connectivity on?one of the downstream ports. The hub includes internal Type-C CC pin logic and an internal USB3.2 Gen 1 multiplexer to support both Type-C insertion orientations. The USB7016 supports an additional 5?x Type A ports downstream - 3 x USB3.2 Gen1 and 2 x USB2.0.?The hub also supports legacy USB speeds (HS/FS/LS) through a dedicated USB2.0 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 USB7016 supports downstream battery charging and integrated battery charger detection circuitry supporting the USB-IF Battery Charging (BC1.2) detection method and most Apple? devices. The USB7016 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 OTPMPLAB? Connect Configurator, Microchip’s proprietary software utility, can be used to program On-chip One Time Programmable (OTP) ROM for the USB7016 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 USB7016 can be configured through a series of external low-cost resistor bootstraps. A handful of bootstrap pins are available on the USB7016 to enable standard configurations for GPIOs and downstream ports. No OTP programming required.Unlike the USB7050/51/52/56, USB7016 applications DO NOT require application-specific firmware developed by Microchip support engineers. There is no native PD firmware included within the USB7016. Microchip's complimentary and confidential MicroCHECK?design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects. You can confidently submit your design materials in a secure and private setting, and our expert engineers will provide individualized feedback to enhance your design.?MicroCHECK?design review service is subject to?Microchip's?Program Terms and Conditions?and requires a myMicrochip?account.
