USB3300-EZK-TR

Controllers Overview

The USB3300-EZK-TR is a Hi-Speed USB Physical Layer Transceiver (PHY) manufactured by Microchip Technology, designed for industrial temperature operation ranging from -40°C to +85°C. It features a ULPI interface compliant with Specification Revision 1.1 in 8-bit mode, converting 54 UTMI+ signals into a standard 12-pin Link controller interface. The device supports USB 2.0 High Speed (480 Mb/s), Full Speed, and Low Speed data rates. Operating voltage ranges from 3.0 V to 3.6 V on the VDD3.3 supply, with internal regulators providing 1.8 V for digital and analog circuits. Typical unconfigured current is 54.7 mA, while suspend current drops to 83 µA. It includes an integrated 24 MHz crystal oscillator, internal PLL, and ESD protection of ±8 kV HBM.

Controllers Procurement Notes

Verify the specific ordering suffix '-TR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance requirements as specified in the manufacturer's documentation. Ensure the industrial temperature grade aligns with the environmental constraints of the target application design.

Controllers Selection Notes

Select this component when a low-latency PHY is required for ASIC, SoC, or FPGA designs utilizing a ULPI link layer. The device is suitable for applications needing minimal external components due to integrated termination resistors and oscillators. Consider the 32-pin QFN package dimensions for PCB layout constraints and thermal management requirements.

Controllers Part Context

This part belongs to the USB3300 series of Hi-Speed USB PHYs. It is distinguished by its native ULPI architecture without wrapper overhead, offering lower latency compared to wrapped UTMI designs. The 'EZK' designation indicates the industrial temperature range and QFN package type, while '-TR' specifies the reel packaging variant.
