The macro M16550, implements a synchronous universal asynchronous receiver/transmitter, which provides an interface between a microprocessor and a serial communication channel.
This macro can be customized according to specific needs (application-specific requirement). Any other pre-designed functions can be integrated into the FPGA. FPGA density and I/O requirements can be defined according to customer specification.
