6.11 10/100Base-TX Ethernet
The EFM32 Giant Gecko GG11 features an ethernet MAC peripheral (ETH) supporting 10 and 100 Mbit/s transfer speeds. The
SLSTK3701A provides the hardware required to communicate with other ethernet devices using standard twisted pair cables, including
a Microchip KSZ8091-RNDCA PHY transceiver, magnetics and an RJ-45 ethernet jack.
Note: due to the power supply requirements of the PHY transceiver, it is not possible to utilize ethernet connectivity while powering the
kit from a CR2032 lithium battery. Refer to the KSZ8091-RNDCA datasheet for detailed electrical specifications including current con-
sumption in different scenarios.
