XR88C192 - Dual Universal Asynchronous Receiver/Transmitter

The XR88C92 and XR88C192 are Dual Universal Asynchronous Receivers and Transmitters (DUART) with an 8 byte (XR88C92) or 16 byte (XR88C192) transmit and receive FIFO.

• The operating speed of the receiver and transmitter can be selected independently from a table of eighteen fixed baud rates, a 16X clock derived from a programmable counter / timer, or an external 1X or 16X clock. The baud rate generator and counter / timer can operate directly from a crystal or from an external clock input. The XR88C92 and XR88C192 provide a power-down mode in which the oscillator is stopped but the register contents are retained. The XR88C92 and XR88C192 are fabricated in an.
