Device Overview

Summary

The Microchip USB84604 is a low-power, OEM configurable, MTT (Multi-Transaction Translator) USB 2.0 hub controller with 4 downstream ports and advanced features for embedded USB applications. The USB84604 is compliant with the USB 2.0 Specification and has passed AEC-Q100 testing. It includes advanced USB features, like; USB 2.0 Link Power Management and High-Speed Inter-Chip (HSIC) USB Electrical Specification Revision 1.0 for low power consumption. The USB84604 will attach to an upstream port as a Full-Speed hub or as a Full-/Hi-Speed hub, while the  4 downstreams ports support Low-Speed, Full-Speed, and Hi-Speed (if operating as a Hi-Speed hub).  The HSIC  interface is available as an updsteram port option, and provides  support  Hi-Speed operation, only.

Meeting the desire of consumers for a “connected vehicle,” Microchip’s FlexConnect technology allows for easy port reversals or “role swapping.” The USB84604’s downstream port 1 is able to swap with the upstream host port, thus transferring the host capability to the product connected to the UCH2, such as smartphones and tablets. This unique capability allows for the smartphone ecosystem of software and applications to be connected to the automobile infotainment system.

The USB84604 has been specifically optimized for embedded systems where high performance, and minimal BOM costs are critical design requirements. Standby mode power has been minimized and reference clock inputs can be aligned to the customer’s specific application. Flexible power rail options ease integration into energy efficient designs by allowing the USB84604 to be powered in a single-source (VBUS (5V), VBAT, 3.3V) or a dual-source (VBAT + 1.8, 3.3V + 1.8) configuration.  The USB-IF Battery Charger specificaiton (revision 1.2) is supported on up and downstream ports,. In  addition, all required resistors on the USB ports are integrated into the hub, including all series termination and pull-up/pull-down resistors on the D+ and D– pins

  • 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 also supported

 

The USB84604 provides for a part type option to enable an USB endpoint dedicated for use as a USB to I2C/SPI interface, thus allowing external circuits or devices to be monitored, controlled, or configured via the USB interface.

*The USBCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.

The USBF129 flash memory device is also offered as a companion chip to the USB84604.  It is factory pre-programmed with application firmware and default hub configuration settings. The USBF129 memory function assures proper functionality, providing for decreased development time and engineering resource, and overall faster time to market.
