CYUSB3302-68LTXIT

Application Specific Microcontrollers Overview

The CYUSB3302-68LTXIT is a USB 3.2 Gen 1 hub controller from Infineon Technologies, part of the EZ-USB™ HX3 family. It supports SuperSpeed (5 Gbps), High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates across two downstream ports. The device integrates an ARM Cortex-M0 CPU with 16 KB RAM and 32 KB ROM for system configuration and firmware execution. It operates at a core voltage of 1.2 V and I/O voltage of 3.3 V, housed in a 68-pin QFN package.

Application Specific Microcontrollers Procurement Notes

Verify the ordering suffix 'IT' against official documentation to confirm industrial temperature range specifications (-40°C to +85°C). Ensure compatibility with required pin-strapping configurations for VID, PID, and port activation settings before procurement.

Application Specific Microcontrollers Selection Notes

Select this model for designs requiring two USB 3.0 downstream ports with integrated power management. Consider the shared link feature if embedding SS devices alongside removable USB 2.0 peripherals. Verify that the 68-pin QFN package fits the PCB layout constraints and thermal requirements.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-USB™ HX3 series, which includes variants with varying numbers of downstream ports (2, 4, 6, or 8). The CYUSB3302 specifically offers two USB 3.0 ports, distinguishing it from higher-port-count models like the CYUSB3304 while sharing the same core architecture and CPU subsystem.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the same family include CYUSB3304 for four-port requirements. Cross-family replacements may involve other USB 3.0 hub controllers, but pin compatibility and firmware support must be verified independently.
