3.5 Ethernet Phy
The optional 10/100 Ethernet physical interface is directly connected to the internal Ethernet MAC and provides
full duplex communication with automatic MDIX support. The Wake On Lan functionality allows reducing power
consumption when in sleep mode.
3.6 High Speed USB Phy
The optional High Speed USB Phy is one of the two USB interfaces available on the high speed connectors and
is also available on the USB-C connector. High Speed USB PHY allows transfer rates of up to 480 Mbps and can
be used both as a host and as a device.
When using the USB-C connector only one USB port is usable on high speed connectors.
When the High Speed USB Phy option is not assembled the USB-C port only one Full Speed port is available and
is shared between USB-C and High Density connectors
3.7 USB-C Connector
USB-C connector supports multiple use case scenarios and provides the following functions:
Provide board power supply in both DFP and DRP mode
Source power to external peripherals when board is powered through VIN
expose High Speed (480Mbps) or Full Speed (12 Mbps) USB Host/Device interface
3.8 Power Tree
All power conversion on the Portenta H7 lite is handled by the PF1550 PMIC. Current is drawn by VUSB, VIN or
VBATT automatically according to rules specified by the PMIC. The VCC is driven by a buck converter configured
to provide 3V3 that is accessible on both the MKR headers and the HDR connector. Two other buck converters
provide 3V1 and 2V8 outputs. Additionally, three precision LDO provide low-ripple outputs of 1V0, 1V2 and 1V8.
Voltage range and max current are provided as a general guideline only. Consult the PF1550 datasheet for
specific details.
