UPD720201K8-711-BAC-M1-A

Controllers Overview

The UPD720201K8-711-BAC-M1-A is a USB 3.0 host controller LSI compliant with the xHCI 1.0 specification and PCIe Gen2 interface. It provides four USB ports supporting SuperSpeed, High-Speed, Full-Speed, and Low-Speed devices. The device operates at a data rate of 5 Gbps and utilizes a 68-pin HVQFN package measuring 8 mm x 8 mm with a 0.5 mm pitch. Electrical requirements include 1.05 V and 3.3 V supply voltages with a 24 MHz crystal clock input. The extended industrial temperature range variant (-40°C to +85°C) is designated by the suffix -711.

Controllers Feature Summary

• Supports up to four USB 3.0 SuperSpeed downstream ports
• Integrates PCI Express Gen2 system interface bus
• Compatible with Intel eXtensible Host Controller Interface (xHCI) 1.0
• Includes firmware download capability without external serial flash ROM

Controllers Applications

• AMD Genoa power and timing systems
• Desktop and laptop computers
• Servers and PCI Express cards
• Digital televisions and set-top boxes
• Network Attached Storage (NAS) and routers

Controllers Procurement Notes

Verify the specific suffix configuration when ordering. The -M1-A suffix indicates a specific manufacturing or testing variation compared to the standard -BAC-A version. Confirm that the -711 designation matches the required -40°C to +85°C operating temperature range for the target application environment before finalizing procurement.

Controllers Selection Notes

Select this component for designs requiring four independent USB 3.0 ports connected via a PCIe Gen2 interface. Ensure the host system supports the xHCI 1.0 standard. Compare against the two-port UPD720202 model if fewer ports are sufficient. Verify that the PCB layout accommodates the 68-pin QFN footprint and thermal requirements for the specified voltage domains.

Controllers Part Context

This part belongs to the Renesas μPD720201 series of third-generation USB 3.0 host controllers. It serves as an upgrade to previous generations, offering improved effective throughput and reduced power consumption in low-power modes. The series is designed to facilitate the integration of high-speed USB interfaces into compact electronic systems.

Controllers Replacement Considerations

The UPD720201K8-701-BAC-A is a functionally similar alternative but operates within a commercial temperature range (0°C to +85°C). Designers requiring the wider industrial temperature range must retain the -711 suffix. No other direct pin-compatible substitutes are documented.
