16550 UART
The
16550 UART (
universal asynchronous receiver transmitter) is made by
National Semiconductor. Both the physical and software interface of the 16550 are backwardly compatibly with the 16450 UART. The 16550 UART offers a 16-byte
FIFO buffer. Now revised to the 16550D. It is a microprocessor designed for implementing the electrical interface for serial communication; it can be used to implement
RS-232, and is commonly found in
personal computers.
