Good afternoon,
I need to replace the 80186 compatible CPU on a design from us by a more modern CPU module that has no data bus but an SPI interface.
I found some SPI-IO expander chips, I could probably use a simple CPLD, but a ready-to-use bridge chip that converts to a 8-bit multiplexed data/address bus would be very nice.
Does anyone know of such a chip?
Thanks, Thomas
