The NS16550AFN is a Universal Asynchronous Receiver-Transmitter (UART) integrated circuit manufactured by Texas Instruments. It is commonly used to implement serial ports in IBM PC compatible computers, connecting to peripherals like modems and serial mice via an RS-232 interface.
Key features of the NS16550AFN include an on-chip FIFO buffer for both incoming and outgoing data, which allows the host system more time to respond to interrupts without data loss. It also incorporates an on-chip baud rate generator to control data transmission and reception rates, and handshake lines for modem control. The interrupt function provides communication with the host microprocessor.
This UART is backward compatible with earlier standards like the 8250 UART and 16450 UART, making it a suitable upgrade for systems requiring higher reliability and stability at higher baud rates. The NS16550AFN is a corrected version of the original 16550, with the 'A' designation indicating this improvement, and newer versions like the 16550D are also available.
