What can be the maximum width of Address bus in AHB Protocol?

Hi AHB-Experts,

I read AHB specification. In signals section its mentioned that HADDR bus size is 32 bits.

I wanted to ask that can we have HADDR bus width more that 32 bits and if so what can be the maximum width for HADDR bus

Regards

  • There is now no maximum width.

    The diagrams in the AHB spec all show 32-bit address buses as that was what was showing in the first few releases of AHB, but the latest AHB5 spec recommends HADDR widths of between 10 and 64 bits.
