Note1: The current module supports an external 10/100 Mbps Ethernet PHY via the RMII interface.
Note2: The logic IO pins are 3.3V tolerant.
Note3: SMT Pins 67 to 75 are the ground pads under the module. These pads must be connected to
ground. These pads also provide thermal relief for the module. It is recommended that multiple vias for
each pad be used to connect the ground pads to the ground plane. Please see the evaluation board layout
as a reference for the ground pad and multiple via in pad recommendation. Contact your local FAE or sales
support for the evaluation kit artwork.
Note 4: All unused IO pins may be left floating, except for the required straps on pins 17, 26, and 29.
Note 5: Asterisk (*) indicates feature available in a future release. Contact your local sales representative
for availability.
