(DC)TR-72D Transceiver Module Data Sheet © 2015 MICRORISC s.r.o. www.iqrf.org Datasheet_TR-72D_151005 Page 1 TR-72D Description (DC)TR-72D is a family of IQRF transceiver modules operating in the 868 MHz and 916 MHz license free ISM (Industry, Scientific and Medical) frequency band. Its highly integrated ready-to-use design containing MCU, RF circuitry, integrated LDO regulator, serial EEPROM, optional temperature sensor and optional on-board antenna requires no external components. Extended RF power result in higher RF range. Ultra low power consumption fits for battery powered applications. MCU with built-in operating system significantly reduces application development time. Optional DPA framework supports applications even without programming. This document is valid for TR as well as DCTR transceiver versions. For simplicity, only TR is used further on throughout the document.

Electrical specifications Typical values unless otherwise stated Parameters specified in this datasheet are typical values. They are at power supply VOUT = 3 V only. VOUT voltage different from 3 V can impact on RF range and other parameters. Supply voltage (VCC) LDO output (VOUT) 3.1 V to 5.3 V +3 V ± 60 mV ( VCC > 3.1 V), 100 mA max.

Frost, condensation or humidity over 85% may disable module functionality. Module suitability should be tested in final application before volume use. Note 2: Arrangement: Two TR-72DA transceivers plugged in DK-EVAL-04x kits, vertically, 1.6 m above the ground, in free space (with reflective planes at min. 100 m distance). Test software: E09-LINK example (STD mode, checkRF(0)), bit rate 19.836 kb/s. Note 3: Additional current is consumed when a peripheral (e.g. watchdog, Brown-out detection etc.) is enabled. Note 4: Depends on interferences. Note 5: Several RF bit rates different from 19.836 kb/s will be available in future IQRF OS versions. Note 6: 916 MHz band will be available in future IQRF OS versions. Caution: Electrostatic sensitive device. Observe appropriate precautions for handling. © 2015 MICRORISC s.r.o. www.iqrf.org Datasheet_TR-72D_151005 Page 3 TR-72D Absolute maximum ratings Stresses above listed maximum values may cause permanent damage to the device and affect device reliability.
