XR68C92/192
PLCC Package
DESCRIPTION
The XR68C92/192 is a Dual Universal Asynchronous Receiver and Transmitter with 8 (XR68C92) / 16 (XR68C192)
bytes transmit and receive FIFO. The XR68C92/192 is a pin-to-pin compatible and an improved version of the
XR68C681 and the Philips SCC68692 UART with faster data access and other additional features. 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 external clock input. The XR68C92/192 provides a
power-down mode in which the oscillator is stopped but the register contents are retained. The XR68C92/192 is
fabricated in an advanced CMOS process to achieve low power and high speed requirements.
FEATURES

16 Bytes transmit/receive FIFO (XR68C192)
Standard baud rates from 50bps to 230.4kbps
Non-standard baud rate of up to 1Mbps
Transmit and Receive trigger levels
Watch dog timer
Programmable clock source for receiver and trans-
mitter of each channel
