USB5816CT-I/KD

Controllers Overview

The USB5816CT-I/KD is a low-power, OEM-configurable USB 3.1 Gen 1 hub controller featuring six downstream ports and one legacy upstream port. It supports Super-Speed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) operations. The device includes one USB Type-C downstream port, four USB 3.1 Gen 1 legacy ports, and one USB 2.0 port. It integrates an internal Hub Feature Controller for USB-to-I2C/SPI/GPIO bridging and supports Battery Charging Specification Revision 1.2. Configuration is managed via configuration straps, OTP ROM, or external SPI ROM. The component operates within the industrial temperature range of -40°C to +85°C and is housed in a 100-pin VQFN package.

Controllers Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) as defined by Microchip's product identification system. Confirm the 'KD' suffix corresponds to the 100-pin VQFN package variant. Cross-reference the manufacturer part number with official datasheets to ensure compatibility with required operating conditions and firmware configurations before procurement.

Controllers Selection Notes

Select this component for designs requiring a 6-port USB 3.1 Gen 1 Smart Hub with dedicated Type-C support. Ensure the design accommodates the 100-pin VQFN package dimensions and thermal requirements. Verify that the host system supports the necessary USB protocols and that external components meet the voltage tolerances for USB 2.0 and USB 3.1 Gen 1 pins.

Controllers Part Context

The USB5816 series represents Microchip's SmartHub family, designed for embedded USB applications requiring advanced OEM configurability. This specific model integrates both USB 2.0 and USB 3.1 Gen 1 controllers in parallel to decouple data transfers. It is intended for high-performance hubs where low power consumption and flexible port control are critical design factors.

Controllers Replacement Considerations

Consult Microchip documentation for direct substitutes within the USB5816 family. Verify pinout compatibility and feature parity if considering alternative hub controllers from other manufacturers. Ensure any replacement supports the required USB 3.1 Gen 1 specifications and industrial temperature range.
