For a project I need to integrate Ethernet with
PIC32MX795F512L. For this I had two choices. I thought of purchasing this Waveshare LAN8720 module and directly using its pins to the pins of MCU or using the LAN8720 IC provided by Microchip and design the circuit.
I looked at the Schematic of wavshare board and the schematic of LAN8720 IC provided by Microchip and found a many difference in the schematics of both so thought of raising the question.
If we look at the schematic of waveshare, PIN 14 which is
nINT/REFCLK is not pulled up to 3.3v whereas in Microchip schematic it is pulled up to 3.3v. Also the
RXD1,RXD0 are not pulled up to 3.3v whereas in Microchip schematic it is pulled to 3.3v. Resistors
R11 R12 R14 have different value if we compare it to Microchips schematic.
I am planning to purchase the
waveshare module and use it in the project. Will it work properly given the conditions above.?
Need help. Thanks.!
