TR-62D
Description
TR-62D is a family of IQRF transceiver modules
intended for Wireless M-Bus. It operates in the 868
MHz license free ISM (Industry, Scientific and Medical)
frequency band. Its highly integrated ready-to-use
design requires no external components. Extra low
power consumption predetermines these modules for
battery powered applications.

Note 1: RF range may change with lower temperature. Frost, condensation or humidity over 85% may disable module
functionality. Module suitability should be tested in final application before volume use.
Note 2: Strongly depends on module orientation and surroundings
Users have to ensure observing local provisions and restrictions relating to the use of short range devices by software,
e.g. the CEPT ERC/REC 70-03 Recommendation and subsequent amendments in EU.
Caution: Electrostatic sensitive device. Observe appropriate precautions for handling.
Absolute maximum ratings
Stresses above listed maximum values may cause permanent damage to the device and affect device reliability.
Functional operation at these or any other conditions beyond those specified is not supported.
