CYUSB2302-68LTXIT

Application Specific Microcontrollers Overview

The CYUSB2302-68LTXIT is a USB 2.0 hub controller from the EZ-USB™ HX3 family, compliant with USB 3.2 Gen 1 specifications. 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, including ghost charging and ACA-Dock modes. The component operates at a 1.2 V core voltage and is available in a 68-pin QFN package.

Application Specific Microcontrollers Feature Summary

• Two downstream ports supporting USB 2.0 High-Speed, Full-Speed, and Low-Speed protocols
• Integrated ARM Cortex-M0 CPU with 16 KB RAM and 32 KB ROM
• Supports USB Battery Charging v1.2, including ghost charging and ACA-Dock functionality
• Vendor-command support for USB-to-I2C bridging and external firmware upgrades

Application Specific Microcontrollers Applications

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

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Confirm that the I2C interface requirements match the design constraints. Ensure the host system supports the necessary vendor-specific commands if utilizing the bridge feature.

Application Specific Microcontrollers Selection Notes

Select this model when only USB 2.0 downstream connectivity is required, as it lacks SuperSpeed PHYs found in other HX3 variants. Verify compatibility with the target operating systems, which include Windows XP through 8.1, Mac OS 10.9, and Linux kernel 3.11. Check if the integrated power switch control meets the overcurrent protection needs of the application.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-USB™ HX3 family of USB hub controllers. Unlike the CYUSB3302, which includes SuperSpeed ports, the CYUSB2302 series is restricted to USB 2.0 downstream connections while retaining the advanced configuration and charging features of the broader HX3 platform.

Application Specific Microcontrollers Replacement Considerations

CYUSB2304-68LTXIT offers four downstream ports instead of two. CYUSB3302-68LTXCT provides two downstream ports but adds SuperSpeed (USB 3.0) capability.
