UPD720211K8-611-BAL-A

Controllers Overview

The UPD720211K8-611-BAL-A is a USB 3.0 host controller LSI manufactured by Renesas Electronics, compliant with the xHCI 1.0 specification and supporting up to four USB ports for SuperSpeed, High-Speed, Full-Speed, and Low-Speed devices. It interfaces with the system via a PCI Express Gen 2 x1 channel and operates on 1.05V and 3.3V power supplies with a 24MHz crystal clock input. The component is housed in a 68-pin QFN package (8mm x 8mm) with a 0.5mm pitch, designed for an operating temperature range of 0°C to +85°C.

Controllers Feature Summary

• Supports four USB ports compatible with USB 3.0 SuperSpeed specifications
• Integrates firmware download functionality without requiring external serial flash ROM
• Features improved data transfer processing circuits for enhanced effective write speeds
• Reduces power consumption in low-power modes compared to previous product generations

Controllers Applications

• Desktop computers and laptops
• Tablets and servers
• PCI Express cards and Express cards
• Digital TVs, set-top boxes, and BD players
• Storage systems, routers, and NAS devices

Controllers Procurement Notes

Verify the specific suffix '611' against official documentation to confirm the commercial temperature range (0°C to +85°C). Ensure compatibility with the 68-pin QFN footprint during PCB layout. Confirm RoHS compliance status through current manufacturer certificates before finalizing procurement plans.

Controllers Selection Notes

Select this model when a four-port USB 3.0 solution is required within a compact 68-pin form factor. Compare against the two-port UPD720202 variant if fewer ports suffice. Verify that the system design accommodates the 1.05V and 3.3V dual-voltage requirements and the 24MHz clock input configuration.

Controllers Part Context

This component belongs to the µPD7202xx series of USB 3.0 host controllers from Renesas. It shares architectural similarities with the UPD720201 but differs in port count and package pinout. The series emphasizes low power consumption and high throughput for modern computing platforms.

Controllers Replacement Considerations

The UPD720201K8-611-BAC-A is a verified substitute offering identical four-port functionality and package dimensions. Ensure the replacement part number matches the required temperature grade and interface specifications.
