CYUSB2302-68LTXI

Application Specific Microcontrollers Overview

The CYUSB2302-68LTXI is a USB 2.0 hub controller from the EZ-USB™ HX3 family, compliant with the USB 3.0 specification revision 1.0. It features two downstream ports supporting High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates. The device integrates an ARM Cortex-M0 CPU with 16 KB RAM and 32 KB ROM for system configuration and battery charging control. It supports USB Battery Charging v1.2, ghost charging, and vendor-command support for USB-to-I2C bridging. The component operates within an industrial temperature range of -40°C to +85°C.

Application Specific Microcontrollers Applications

• Standalone hubs
• PC and tablet motherboards
• Docking stations
• Hand-held cradles

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix 'LTXI' against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with required I2C EEPROM or master configurations if firmware upgrades are needed. Confirm pin-strapping requirements for VID, PID, and port activation settings prior to integration.

Application Specific Microcontrollers Selection Notes

Select this model when only USB 2.0 downstream connectivity is required, as it lacks SuperSpeed PHYs found in CYUSB330x variants. Verify that the 68-pin QFN package fits the PCB layout constraints. Check if shared link or ACA-Dock features are necessary; if so, consider CYUSB331x or CYUSB332x series instead.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-USB™ HX3 family of USB hub controllers. Unlike the CYUSB330x series which includes SuperSpeed ports, the CYUSB230x series focuses on USB 2.0 compliance while retaining advanced features like ghost charging and embedded CPU control. It serves as a cost-effective solution for systems requiring multiple USB 2.0 connections without high-speed data throughput needs.

Application Specific Microcontrollers Replacement Considerations

CYUSB2304-68LTXI offers four downstream ports with identical electrical characteristics. CYUSB3302-68LTXCT provides two downstream ports but adds SuperSpeed capability.
