XR88C92/192  
DUAL UNIVERSAL ASYNCHRONOUS  
RECEIVER AND TRANSMITTER  
June 2003  
DESCRIPTION  
TheXR88C92/192isaDualUniversalAsynchronousReceiverandTransmitterwith8(XR88C92)/16(XR88C192)  
bytes transmit and receive FIFO. The XR88C92/192 is a pin and functional replacement for the SC26C92 and an  
improvedversionofthePhilipsSCC2692UARTwithfasterdataaccessandotheradditionalfeatures.Theoperating  
speed of the receiver and transmitter can be selected independently from a table of eighteen fixed baud rates, a
