FPGA remote slow control via UART 16550

Hardware

Buffering

Remember to add a voltage translator buffer:

!! none of the FPGAs on the market is 12V tolerant !!

~ use a MAX3224 chip for example

Timing

In case an external clock is needed to drive the UART:

~ use a 29.4912 MHz Oscillator like ASV-29.4912MHZ-EJ-T
