Microchip Technology USB7252 4-Port Gen2 SmartHub™ Evaluation Board

Microchip Technology USB7252 4-Port Gen2 SmartHub™ Evaluation Board provides the necessary requirements and interface options to evaluate the USB7252 IC. This USB7252 SmartHub IC is a 4-port SuperSpeed+ (SS+) USB IC on a 4-layer RoHS-compliant Printed Circuit Board (PCB). The EVB-USB7252 from Microchip Technology comes with four configurations for operation through internal default settings. This evaluation board supports custom configurations either via I2C or through the external 16-Mbit SPI flash device. The EVB-USB7252 exhibits driver compatibility with Microsoft® Windows® 10, Windows 8.x, Windows 7, Windows XP, Mac OS® X 10.4+, and Linux® hub drivers.

The EVB-USB7252 board is compliant with the USB 2.0 High-Speed (HS), Full-Speed (FS), and Low-Speed (LS) USB signaling. Additionally, this board is also compliant with USB 3.2 Gen2 on the upstream port and on three of the downstream ports including two USB Type-C™ interfaces. The EVB-USB7252 board platform supports battery charging on all six downstream ports (maximum of 10A) at any one time.
