dual color LED is
1.4% of the FPGA price and about 80% of the PCB price (PCB quoted in 10k qty) but well yes its still a tiny factor
thanks for the part numbers - they are so venerable that google has trouble finding the datasheets, but st.com has them online
and no the PDM (as in 4089) is not same as delta-sigma, so I will possible write the 4089 in VHDL just for the demo
there is a user slot with 6 FPGA pins so the IR thing should got there
One-Wire (as per dallas 1-wire) is does depend on known frequency, it is not fully self-adjusting (and can not be)
1-wire (a dallas) are not autobaud, many uart on one wire are autobauding
