With a CPLD you can now easily generate the Intel signals needed for this IC. Yes, but all of the SW out there for uart carts is designed to use the 6551 (well, there might be some SW for the ide64 shortbus uart expansion, but I've not heard of many apps for it). I suppose one could emulate the 6551 registers and convert them to a 16550, but the T232 can do 230400 bps, so speed is not an issue (FIFOs are a value add for the 16550 and higher ICs, though). I appreciate the "clean sheet" approach to hardware design, but my philosophy trends to the "make it compatible" side.
