                        these devices very easy by mounting the modules on small circuit
                        boards  with  connectors  and  a  place  to  solder  on  the  antennas
                        (which are included with the modules).
                        The LC Series is ideally suited for volume use in applications such
                        as remote control, security, identification, robotics, and periodic
                        data transfer. Packaged in a compact SMD package, the LC trans-
                        mitter utilizes a highly optimized SAW architecture to achieve an
                        unmatched blend of performance, size, efficiency, and cost. When
                        paired with a matching LC series receiver, a highly reliable wire-
                        less link is formed, capable of transferring serial data at distances
                        in  excess  of  300  feet.  No  external  RF  components,  except  an
                        antenna, are required, making design integration straightforward.
                        The  features  include:  low  cost,  no  external  RF  components
                        required, ultra-low power consumption, compact surface-mount
                        package,  stable  SAW–based  architecture,  support  data  rates  to
                        5,000 bps, wide supply range (2.7-5.2 vdc), direct serial interface,
                        low  harmonics,  and  no  production  tuning.  The  receiver  module
                        pinout  diagram  is  shown  in  Figure  6.35.  Using  the  module  to
                        receive information from the transmitter will be described when
                        programming is covered.
