  • Page 10: Power Supply

    RX65N Envision Kit 2 Power Supply 2. Power Supply Requirements With the display backlight enabled, and operational, the RX65N Envision Kit can typically draw 170mA from the 5V supply provided from the mini-B USB connection CN9. This is a typical figure and not worst case, so it is recommended that the RX65N Envision Kit be supplied from a USB supply capable of supplying at least 500mA.

  • Page 21: Ethernet

    When running any Ethernet software, a unique MAC address should be used. As the Envision Kit is not fitted with an Ethernet transceiver IC or Connector by default, it is not supplied with a unique Renesas allocated MAC address. It is recommended that a unique MAC address should be always be used with this device ensured to ensure full compatibility when using other hardware on a common Ethernet connection.

  • Page 22: Ethernet Connector And Rmii Transceiver Ic

    RX65N Envision Kit 4 Envision Kit Circuitry Note that with the LAN8720A configured to provide the 50MHz clock-out signal from the 25MHz crystal oscillator, the worst-case output delay time for the RX65N Ethernet controller (15ns) combined with the worst case setup time for the LAN8720A (7ns) exceeds the 20ns clock period for the RMII interface. In practice the combined controller delay time and transceiver setup time does not exceed the clock period.
