CYUSB3302-68LTXC

Application Specific Microcontrollers Overview

The CYUSB3302-68LTXC 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 features two downstream ports supporting SuperSpeed (5 Gbps), High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps). The device integrates an ARM Cortex-M0 CPU with 16 KB RAM and 32 KB ROM for system configuration and charging control. Electrical specifications include a 1.2 V core supply voltage and operation within a commercial temperature range of 0°C to +70°C. It utilizes a 68-pin QFN package.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix '68LTXC' against official Infineon documentation to confirm the exact package type, tape-and-reel quantity, and industrial/commercial temperature rating. Ensure compatibility with the required I2C EEPROM or pin-strap configuration method for the target application.

Application Specific Microcontrollers Selection Notes

Select this component when a two-port USB 3.0 hub solution is required with integrated firmware capabilities via the Cortex-M0 processor. Consider the CYUSB3304 if four downstream ports are needed, or the CYUSB331x series if shared link functionality for embedded devices is necessary.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-USB™ HX3 family of USB 3.2 Gen 1 hub controllers. The family includes variants with different port counts (2, 4, 6, 8) and feature sets such as shared links and ACA-Dock support. The CYUSB3302 specifically provides a compact 2-port solution suitable for space-constrained designs.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the same family include the CYUSB3304 for a 4-port configuration. For applications requiring shared link capabilities, consider the CYUSB3312. Verify pinout and electrical characteristics before substitution.
