    Hi,
    We received the obsolescence notification on BCM53108 (EOL-CCX-001559).
    I am looking for a
    --- long term available alternative
    --- preferably compatible on SPI control
    Any advice?
    Greetings, Henry Kompagnie (Benchmark Electronics)

    Hi Henry,

    Per your descriptions, the BCM53108 is our multiport 10/100Mbps Ethernet Switch and it is [8FE port + one RGMII/GMII/MII/RvMII/TMII/RvTMII uplink port] Switch.

    Suggest the alternative chip for your case is our the other multiport Gigabit Ethernet Switch BCM53128, BCM53128 is [8GE port + one RGMII/GMII/MII/RvMII/TMII/RvTMII uplink port] Switch.

    BCM53128 is pin to pin compatible with BCM53108

    But when you change chip to BCM53128 on your BCM53108 board, it requires to use your SW to configure BCM53128 registers Reg(0x10-0x17: 0x12) bit[9:8]=00 via SPI to disable the front ports 1000BASE-T capability.

    Please let me know if there is any questions.

     

    Thanks,

    Ryan
