LPC54S016JBD100 Valid Address Mac

worosco — Thu, 11 Jan 2024 18:11:57 GMT

My application will be responsible for propagating the telemetry of my equipment to some systems. For this I will use an LPC54S016JBD100 that already has an Ethernet PHY. In order for me to place my equipment on my clients' network, via DNS or fixed IP, I will need a valid MAC ADDRESS according to EUI-48, I would like to know if the LPC54S016JBD100 already comes with a MAC ADDRESS from the factory and if it does, is it unique? for each microcontroller?

Hi,

As the section 37.6.28 MAC address high register in UM11060.pdf, there are two mac registers to save 48 bits mac address: MAC_ADDR_HIGH and MAC_ADDR_LOW, the MAC_ADDR_LOW saves 32 bits low mac address, the MAC_ADDR_HIGH saves high 16 bits mac address.

It is required for user to assign mac address to the mac address register with firmware, there is not default value for the two registers.

Hope it is helpful
