UPD720210K8-BAF-M1-A

Controllers Overview

The UPD720210K8-BAF-M1-A is a USB 3.0 host controller LSI compliant with the xHCI 1.0 specification. It features a PCIe Gen2 x1 system interface and provides four USB ports supporting Super Speed (SS), High Speed (HS), Full Speed (FS), and Low Speed (LS) devices. The component operates on 1.05V and 3.3V supplies with a 24MHz crystal clock input. It utilizes a 68-pin HVQFN package measuring 8mm x 8mm with a 0.5mm pitch. The device supports an operating temperature range of -40°C to +85°C and includes firmware download capabilities without external serial flash ROM.

Controllers Feature Summary

• Supports four independent USB ports for simultaneous connection of multiple peripherals across all speed grades.
• Integrates a PCIe Gen2 x1 interface for high-bandwidth communication with the host processor.
• Eliminates the need for external serial flash memory through built-in firmware download functionality.

Controllers Applications

• Desktop and laptop computer motherboard expansion
• Industrial control systems requiring high-speed data transfer
• Embedded servers and network attached storage (NAS) devices

Controllers Procurement Notes

Verify the specific suffix M1-A against official Renesas documentation to confirm package variant and testing status. Ensure compatibility with the target PCB layout for the 68-pin HVQFN form factor. Confirm that the design supports the required 1.05V and 3.3V power rails and 24MHz clock source before finalizing procurement.

Controllers Selection Notes

Select this model when four USB 3.0 ports are required within a compact footprint. Compare against the two-port UPD720202 if fewer ports suffice, as it uses a smaller 48-pin package. Ensure the host system supports PCIe Gen2 x1 lanes and xHCI drivers compatible with Intel specification revision 1.0.

Controllers Part Context

This component belongs to the Renesas UPD7202xx series of USB 3.0 host controllers. It shares architectural similarities with the UPD720201 but differs in pin count and port configuration. The series is designed to replace legacy USB 2.0 controllers while maintaining backward compatibility with existing USB protocols.

Controllers Replacement Considerations

Direct substitutes include the UPD720201K8-711-BAC-A for equivalent four-port functionality. Verify pin-to-pin compatibility and thermal requirements when replacing older UPD7202xx variants in existing designs.
