INS8250 Datasheet - National Semiconductor

INS8250 Asynchronous Receiver/Transmitter

Each of these parts function as a serial data input/output interface in a microcomputer 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 pe.

INS8250 Features

* Easily interfaces to most popular microprocessors.

* Adds or deletes standard asynchronous communication bits (start, stop, and parity) to or from serial data stream.

* Holding and shift registers eliminate the need for pre cise synchronization between the CPU and the serial data.
