UPD720211K8-611-BAL-A#YK1

Controllers Overview

The UPD720211K8-611-BAL-A is a USB 3.0 host controller LSI compatible with the xHCI 1.0 specification. It provides four USB ports supporting Super Speed (SS), High Speed (HS), Full Speed (FS), and Low Speed (LS) devices. The system interface utilizes a PCIe Gen2 x1 channel compliant with the PCIe 2.0 basic specification. Electrical requirements include 1.05V and 3.3V supply voltages, driven by a 24MHz crystal clock input. The component is housed in a 68-pin HVQFN package measuring 8mm x 8mm with a 0.5mm pitch. This specific variant operates within an ambient temperature range of 0°C to 85°C.

Controllers Feature Summary

• Supports USB 3.0 specifications with integrated xHCI 1.0 compliance for efficient data transfer management.
• Integrates four independent USB ports capable of handling all standard speed classifications simultaneously.
• Features internal firmware download capabilities, eliminating the need for external serial flash memory components.

Controllers Applications

• Desktop and laptop computer systems
• Tablet computers and mobile computing devices
• Server infrastructure and PCI Express expansion cards
• Digital televisions and set-top boxes
• Network Attached Storage (NAS) and storage routers

Controllers Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm the operating temperature range and package revision. Ensure the design supports the required 24MHz crystal oscillator and dual voltage rails. Confirm that the 68-pin QFN footprint matches the PCB layout specifications provided in the hardware manual.

Controllers Selection Notes

Select this model when four USB 3.0 ports are required with a PCIe Gen2 interface. Consider the -611 suffix for commercial temperature ranges instead of industrial grades. Evaluate the 68-pin package constraints against available board space compared to the two-port alternative.

Controllers Part Context

This component belongs to the Renesas UPD7202xx series of USB 3.0 host controllers. It serves as a high-performance solution for connecting multiple peripherals via the USB standard. The series includes variants with different port counts and temperature ratings to suit various consumer and industrial electronics designs.

Controllers Replacement Considerations

The UPD720201K8-711-BAC-A offers identical functionality but supports an extended industrial temperature range of -40°C to 85°C. Designers requiring wider thermal tolerance should consider this equivalent part number while maintaining the same pinout and electrical characteristics.
