INS8250-B Datasheet | National Semiconductor

INS8250/INS8250-B National Sem iconductor INS8250, INS8250-B Universal Asynchronous Receiver/Transmitter General Description Each of these parts function as a serial data input/output interface in a microputer system. The system software determines the functional configuration of the UART via a TRI-STATE® 8-bit bidirectional data bus. The UART performs serial-to-parallel conversion on data characters received from a peripheral device or a MODEM, and parallel-to-serial conversion on data characters re­ ceived from the CPU. The CPU can read the plete status of the UART. Status information reported includes the type and condition of the transfer operations being per­ formed by the...
