1. Processor running at full speed. Contact the Sales Office for details of special low power variants.
2. The ‘Host Ready Input’ and the ‘Serial Data Input’ have ‘weak’ internal pull-ups enabled. These
3. When power is first applied to the module the processor retrieves ‘calibration’ data for the RF section
4. During power up the Busy Output line goes high.
5. Contact the Sales Office for special ‘fast’ versions that can incorporate internal ‘duty cycling’ to
6. Serial data rate up to 38.4k standard but 76.8k available on request.
inputs should not however be left ‘floating’ but should be tied to either Vcc or Ground 0 Volts.
that compensates for temperature and power supply voltage variations. The transceiver will then be
ready to receive (default) or transmit. It would normally be left in this powered state ready to receive
data.
further reduce quiescent power consumption for battery powered applications.
