CYUSB3326-88LTXCT

Application Specific Microcontrollers Overview

The CYUSB3326-88LTXCT 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 up to six downstream ports: two SuperSpeed (5 Gbps) and four USB 2.0 High-Speed (480 Mbps). The device integrates an ARM Cortex-M0 CPU with 16 KB RAM and 32 KB ROM for system configuration and charging control. Key features include shared link capability, ghost charging, ACA-Dock support, and BC v1.2 compliance. It operates on a 1.2 V core supply and 3.3 V I/O supply, housed in an 88-pin QFN package.

Application Specific Microcontrollers Feature Summary

• Six-port configuration with two SuperSpeed (5 Gbps) and four USB 2.0 (480 Mbps) downstream ports
• Integrated ARM Cortex-M0 CPU with 16 KB RAM and 32 KB ROM for firmware and configuration management
• Supports shared link mode to split one SS port into embedded SS and removable USB 2.0 connections
• Includes ghost charging and ACA-Dock functionality for host-independent device charging

Application Specific Microcontrollers Applications

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

Application Specific Microcontrollers Procurement Notes

Verify the ordering suffix 'T' indicates reel packaging as per Infineon documentation. Confirm the specific silicon revision matches design requirements. Ensure the 88-pin QFN footprint aligns with PCB layout guidelines. Check for RoHS compliance status in the latest datasheet revision.

Application Specific Microcontrollers Selection Notes

Select this model when six downstream ports are required, specifically needing two SuperSpeed and four USB 2.0 connections. Consider the CYUSB3324 if only four SuperSpeed ports are needed. Verify that the application requires the shared link feature or specific charging standards like BC v1.2 supported by this controller.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-USB HX3 family of USB 3.2 Gen 1 hub controllers. Other variants in the series include CYUSB3324 (4 SS ports), CYUSB3328 (4 SS/4 HS ports), and CYUSB3312 (2 SS ports). The family shares common architecture but differs in port count and specific feature sets like ACA-Dock support.
