CYUSB3314-88LTXCT

Application Specific Microcontrollers Overview

The CYUSB3314-88LTXCT is a USB 3.2 Gen 1 hub controller from the EZ-USB™ HX3 family, compliant with USB 3.0 specification revision 1.0. It supports four downstream ports operating at 5 Gbps, with backward compatibility for High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) devices. The component integrates an ARM® Cortex®-M0 CPU with 16 KB RAM and 32 KB ROM, alongside dedicated transaction translators. Key features include Shared Link capability for embedded applications, Ghost Charging support, and ACA-Dock functionality. Configuration is managed via pin-straps or I2C interfaces.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Ensure that any assumed functional differences based on suffixes are validated by the manufacturer's datasheet rather than distributor descriptions.

Application Specific Microcontrollers Selection Notes

Select this model for designs requiring four SuperSpeed downstream ports with integrated power management and configuration flexibility. Consider the 88-pin QFN package dimensions and thermal requirements. Verify compatibility with the target operating system and ensure sufficient GPIO availability for overcurrent detection and LED status indicators.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-USB™ HX3 product family, which includes variants with two, four, six, or eight downstream ports. The CYUSB3314 specifically provides four USB 3.0 ports within the 88-pin QFN package option, distinguishing it from the 68-pin QFN and 100-ball BGA packages available in the broader series.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the same family include CYUSB3304 (four ports, 68-pin QFN/BGA) and CYUSB3324 (four ports, 88-pin QFN). Verify pinout compatibility and package dimensions before substitution.
