XR18W750
WIRELESS UART CONTROLLER
MARCH 2008
GENERAL DESCRIPTION
The XR18W750 is a Wireless UART Controller with a
two-wire I 2 C interface to the XR18W753 RF
transceiver to complete Exar ’s Wireless UART
chipset solution. The XR18W750 supports both the
parallel and serial interfaces to any host system thus
providing flexibility for system designers to select
their interface option.
The XR18W750 includes an embedded 8051
microprocessor which provides the power to process
the protocol framing for data transmission and to
handle error processing. Internally, the XR18W750
REV. 1.0.0
