Part Number: MSP430F5529
Other Parts Discussed in Thread: DP83867CR, DP83TG721S-Q1, USB-2-MDIO

Tool/software:

Hello Application Team:

   we saw there have DP83TG721S-Q1 + DP83867CR T1 to RJ45 by using  MCU MSP430F5529IPN from Ti.com (DP83TG721S-EVM)

we would like use the following block diagram use the MCU as MAC control both two PHY data speed. do you have example code driver can share for us? 

thank you

    Hi Roy,

    It looks like your block diagram did not attach. If it is similar to the schematic of the DP83TG721S-EVM, the MCU does not serve as MAC. The MCU is connected to the two PHY's via MDIO and MDC. In this system, the DP83867CR must be configured to 1000BASE-T as the DP8383TG721S-Q1 only supports this data rate. If this is the only configuration needed for your system, this can be done with strapping on the DP8383TG721S-Q1 PHY. If you need to control other PHY register settings with the MCU, USB-2-MDIO software can be used with the MSP430F5529IPN. 

    Best regards,

    Greg
