Part Number: MSP432E401Y
Other Parts Discussed in Thread: DP83TD510E, USB-2-MDIO
Hello, I am designing a board based on the DP83TD510E EVM, where I need to convert from 2-pair Ethernet to Single-Pair Ethernet. To exchange information with the DP83TD510E and DP83822 PHYs, I need a MDIO interface.
Due to some device specifications, the board has a 3-port Ethernet Switch, which I am using to interconnect the signal from the RJ45 connector, the DP83822 PHY and a MCU (MSP432 is the one I am currently using). But this MCU has no MDIO external interface that I can use to manage the DP83822 and DP83TD510E PHYs, so I need a MCU that has a MDIO interface I can use.
Due to the fact that the MCU has to be connected to the Ethernet Switch as well, I can't use another MCU with a USB-2-MDIO interface (I have only seen it in MSP430 with no Ethernet MCUs), and the device can't afford to have 2 MCUs, one for each task, so my questions are:
Is there any implementation of a bitbanger MDIO interface like USB-2-MDIO but for MSP432?
Or is there any MCU with integrated PHY that has an external MDIO interface as well?
I am trying to avoid using a MCU with an external PHY because I need to save money and space, so it will be my last option.
Thanks in advance.
