Hi-Speed USB Transceiver with 1.8V-3.3V ULPI Interface - 26MHz Reference Clock The USB3317-CP-TR is a USB 2.0 high-speed ULPI transceiver manufactured by SMSC (now part of Microchip Technology). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Interface Type:** ULPI (UTMI+ Low Pin Interface)  
- **USB Compliance:** USB 2.0 High-Speed (480 Mbps)  
- **Operating Voltage:** 1.8V (core), 3.3V (I/O)  
- **Package:** 24-pin QFN (4mm x 4mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Compliance:** USB-IF certified  

### **Descriptions:**  
- The USB3317-CP-TR is a low-power, high-performance USB 2.0 transceiver designed for embedded applications.  
- It supports the ULPI interface, reducing pin count compared to UTMI while maintaining high-speed USB functionality.  
- It integrates termination resistors and signal conditioning for robust USB connectivity.  

### **Features:**  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **Integrated Termination:** Built-in USB termination resistors.  
- **ULPI Compliance:** Reduces system-level pin count.  
- **Signal Conditioning:** Improves signal integrity for reliable USB communication.  
- **Small Form Factor:** 24-pin QFN package for space-constrained designs.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
