USB3300-EZK

Controllers Overview

The USB3300-EZK is an industrial temperature Hi-Speed USB Physical Layer Transceiver (PHY) manufactured by Microchip Technology. 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 operation at 480 Mbps and operates within a supply voltage range of 3.0V to 3.6V. Typical unconfigured current is 54.7mA, while suspend current is 83µA. It includes an internal 24MHz crystal oscillator, PLL for 480MHz operation, and integrated ESD protection rated at ±8kV HBM and ±15kV air discharge. The component is housed in a 32-pin QFN package measuring 5mm x 5mm with a height of 0.90mm.

Controllers Feature Summary

• Supports Host, Device, and On-The-Go (OTG) modes via the ULPI interface
• Integrated ESD protection withstands IEC61000-4-2 tests without external devices
• Includes internal comparators for VBUS level monitoring and OTG protocol support
• Features low latency transmit and receive times due to wrapper-less architecture

Controllers Applications

• Cell Phones
• Digital Still and Video Cameras
• Portable Media Players
• External Hard Drives
• Scanners

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure that the procurement channel provides traceability to Microchip Technology Inc. to guarantee authenticity. Cross-reference the datasheet revision number with the silicon revision to ensure compatibility with any known errata sheets published by the manufacturer.

Controllers Selection Notes

Select this component when a design requires a discrete PHY to connect a ULPI-compliant link layer to a USB 2.0 connector. It is suitable for applications needing full UTMI+ Level 3 functionality with reduced pin count. Consider the industrial temperature range (-40°C to +85°C) if operating in harsh environments. Verify that the host controller supports the 12-pin ULPI interface timing requirements.

Controllers Part Context

The USB3300-EZK belongs to the USB3300 series of Hi-Speed USB PHYs from Microchip Technology. It is designed to complement ASICs, SoCs, or FPGAs equipped with ULPI cores. The -EZK suffix typically denotes the specific 32-pin QFN package variant available in tray packaging, distinguishing it from tape-and-reel options like the -TR suffix.
