As title indicated, I am wondering if we can use a different Ethernet Phy in customized PCB. We have a board that was developed around STM32F407VE, with Ethernet Phy IC DP83848C as the one used by Arch_Max board.
Is it possible to replace STM32F407VE with STM32F437VE? Mostly for TRNG which STM32F407 doesn’t have and also for more RAM which will be needed when working with TLS. u-blox C030-R412M board uses STM32F37 but uses a different Ethernet Phy. It will be ideal if we can just replace the MCU then build a derivative of u-blox C030-R412M .
Please advise. Thanks.
