I'm trying to connect 32 I²C "root of trust" NXP A71CH devices.
I'm trying to multiplex 32 devices for that chip.
I'm looking for a very fast way of multiplexing those 32 devices, an idea or schematic or a design.
The only solution that I found is to use an FPGA. Is there a clever solution with just normal embedded microcontrollers ?
One chip costs 50ms, If I want to do 1000 signing, it would cost 1000*50ms. What I want to achieve is to have 1000signing with just 50ms cost. Is there a way of that without using FPGAs ?! Only with discrete components
