概要

Description

The CYUSB3304-68LTXI is a USB Type-C port controller from Infineon (formerly Cypress). It supports USB 3.1 Gen 1 (5Gbps) and USB Power Delivery (PD) 3.0, enabling power negotiation up to 100W (20V/5A).
Key features:
- Dual-Role Port (DRP): Functions as a host (DFP) or device (UFP).
- Alternate Mode Support: Enables DisplayPort, Thunderbolt, etc.
- Integrated CC Logic: Simplifies Type-C cable detection and orientation.
- Small 68-QFN Package: Suitable for space-constrained designs.
Applications include docks, monitors, laptops, and peripherals. It requires minimal external components, reducing BOM cost.
For detailed specs, refer to the datasheet on Infineon’s website.
