USB5826C-I/KD

Controllers Overview

The USB5826C-I/KD is a low-power, OEM-configurable USB 3.1 Gen 1 hub controller featuring six downstream ports and one legacy upstream port. The port configuration includes two USB Type-C downstream ports, two legacy SuperSpeed downstream ports, two USB 2.0 downstream ports, and one upstream port. It supports SuperSpeed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) operations. The device integrates an internal Hub Feature Controller for I2C/SPI/GPIO bridging and supports USB-IF Battery Charging Revision 1.2 profiles including DCP, CDP, and SDP. It operates within a commercial temperature range of 0°C to +70°C.

Controllers Feature Summary

• Native support for dual USB Type-C downstream ports with integrated multiplexing and PHY power management
• Internal Hub Feature Controller enabling USB-to-I2C/SPI/GPIO bridge functionality for system monitoring and control
• Comprehensive battery charging support compliant with USB-IF BC1.2 standards and various regional emulation protocols
• Advanced signal integrity features including PortSwap for differential pair alignment and PHYBoost for programmable drive strength

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• Multi-function USB 3.1 Gen 1 Peripherals

Controllers Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature grade (-40°C to +85°C) rather than commercial grade when sourcing. Confirm package type is 100-pin VQFN. Check for latest errata sheets regarding silicon revisions. Ensure SPI or OTP configuration requirements match the target design constraints before ordering.

Controllers Selection Notes

Select this component for designs requiring native USB Type-C integration alongside legacy USB 2.0 ports. Consider the internal Hub Feature Controller if external MCU resources are limited. Evaluate PortSplit capabilities if parallel enumeration of USB 2.0 and USB 3.1 devices on specific ports is required. Verify compatibility with host operating systems such as Windows 10/8/7 and Linux.

Controllers Part Context

The USB5826C belongs to Microchip's SmartHub family of USB 3.1 Gen 1 controllers. It is designed to decouple SuperSpeed data transfers from slower USB 2.0 traffic bottlenecks. The device combines a dedicated USB 2.0 hub controller with a parallel SuperSpeed controller, offering enhanced reliability and interoperability compared to single-controller solutions.

Controllers Replacement Considerations

USB5906C/KD: 6-port hub with different port configuration. USB5916C/KD: 6-port hub variant. USB5926C/KD: 6-port hub with multiple Type-C UFP/DFP support.
