UPD720202K8-711-BAA-A

Controllers Overview

The UPD720202K8-711-BAA-A is a USB 3.0 host controller LSI manufactured by Renesas Electronics, compliant with the xHCI 1.0 specification. It features two USB SuperSpeed ports supporting LS, FS, HS, and SS modes, interfacing via a PCI Express Gen 2 x1 system bus. The device operates at data rates up to 5Gbps with supply voltages of 1.05V and 3.3V, utilizing a 24MHz crystal clock input. Housed in a 48-pin QFN package (7mm x 7mm), it supports an extended operating temperature range from -40°C to +85°C. Key electrical parameters include a minimum voltage of 3V for specific logic sections and compliance with MSL 3 standards.

Controllers Feature Summary

• Supports firmware download directly from system BIOS via SPI type ROM interface, eliminating the need for external serial flash memory components.
• Delivers improved effective throughput with data write speeds exceeding previous generations by over 40% through optimized transfer processing circuits.
• Achieves significant power efficiency with low-power mode consumption reduced to 4.5mW, representing a 90% decrease compared to prior product iterations.

Controllers Applications

• Desktop computers and laptop systems
• Tablets and mobile computing devices
• Servers and PCI Express expansion cards
• Digital televisions and set-top boxes
• Network Attached Storage (NAS) and routers

Controllers Procurement Notes

Verify component authenticity through official Renesas channels or authorized distributors. Confirm the suffix '711' indicates the industrial temperature grade (-40°C to +85°C). Check current lead times as market demand may cause fluctuations. Ensure PCB layout adheres to the 48-pin QFN thermal and electrical requirements specified in the datasheet.

Controllers Selection Notes

Select this model for designs requiring exactly two USB 3.0 ports on a PCIe Gen 2 interface. Choose the '711' suffix variant when operation in environments below 0°C is required, as opposed to the '701' commercial grade. Consider the compact 7x7mm footprint for space-constrained motherboards or embedded controllers where external firmware storage must be avoided.

Controllers Part Context

This component belongs to the third-generation μPD72020x series of USB 3.0 host controllers. It serves as the two-port counterpart to the four-port UPD720201 series. Both variants share identical core architectures, power management features, and BIOS-based firmware loading capabilities, differing primarily in port count and package pin configuration.

Controllers Replacement Considerations

The UPD720202K8-701-BAA-A is a verified substitute offering identical functionality within the commercial temperature range (0°C to +85°C). Designers requiring wider thermal tolerance must retain the '711' suffix. No direct pin-compatible alternatives exist for different port counts without schematic modifications.
