Microchip Technology EVB-USB4x12 User Manual page 11

The EVB-USB4x12 is a 4-layer RoHS-compliant evaluation board that utilizes the
USB4712/USB4912 to provide a fully functional 1-port hub with battery charging capa-
bilities. The EVB-USB4x12 also features the UCS2114 two channel USB port power
controller. The USB4712/USB4912 may optionally execute firmware from an external
SST26VF016B SPI Flash device included in the PCB. Many configurable options may
be controlled through the MPLAB Connect Configurator tool. The EVB-USB4x12
demonstrates driver compatibility with native Microsoft
Linux
The EVB-USB4x12 provides the following features:
• USB4712 or USB4912 in a 40-pin QFN RoHS compliant package
• One UCS2114 in a 20-pin QFN RoHS compliant package
• SST26VF016B in a 8-pin SOIC RoHS compliant package
• USB 2.0 compliant (HS, FS, and LS operation); USB pins are 5V tolerant
• Self-powered (external 5V source) or Bus-powered (powered from USB VBUS)
operation
• One USB2.0 Type-A downstream port on EVB-USB4712. Two USB2.0 Type-A
downstream ports on EVB-USB4912
• Battery Charging support (BC1.2 CDP and DCP) on the downstream port (Port 1
of EVB-USB4912)
• Downstream ports support individual port power and over current sense
• MCP1825 on board +3.3V, 1 Amp regulator
• LED indicators for:
- 3.3V board power
- Downstream port VBUS
- Reset
- SPI chip activity
