TR-55D
Description
TR-55D 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 requires no external
components. Extra low power consumption fits for battery
powered applications. Vertical mounting and small
dimensions allow space saving.

Note 1: RF power and other parameters depend on supply voltage. Refer to datasheets of MCU and RF IC used. Test your
application with respect to required supply voltage range.
Note 2: 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 3: RF range strongly depends on module orientation and surroundings.
Note 4: Additional current is consumed when a peripheral (e.g. watchdog, Brown-out detection etc.) is enabled.
Note 5: Depends on interferences.
Note 6: Bit rates different from 19.2 kb/s are preliminary, for experimental purpose only.
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

Note 7: This pin is used as output during initial ~250 ms boot-up to recognize programming mode.
Note 8: External pull-up resistor must be used on this pin when used for RFPGM termination.
There are no on-board protection series resistors on I/O pins. It is recommended to use series resistors 200 Ω on each pin.

Application
Assembly
Vertical mounting:
TR-55Dx should be soldered mounted through two holes in the application board. It is not intended for SMT reflow
soldering.
Top view, units: mm
Recommended PCB layout for user application
SIM connector:
TR-55Dx can also be mounted in SIM connector. Recommended SIM connector: KON-SIM-01.
TR-55Dx must not be plugged in devices like DK-EVAL-04 with power supply out of the TR-55Dx range. Such kits are
intended for TR modules with built-in LDOs only. For using TR-55Dx with such a kit the KON-TR-01L adapter is intended.
See the KON-TR-01L User's guide.
As a suitable kit for TR-55Dx the DK-EVAL-04A is recommended.
Operating system
See IQRF OS User's guide and IQRF OS Reference guide.
Software
See Application examples www.iqrf.org website.
Programming
There are the following possibilities to upload an application program in TR-55Dx modules:
• Wired upload with TR-55Dx plugged via the SIM connector in the CK-USB-04 or CK-USB-04A programmer.
• For TR-55Dx modules populated in an application:
• Wired upload using the CK-USB-04A programmer. See the CK-USB-04A User's guide.
• Wired upload using the CK-USB-04 programmer and the KON-TR-01P adapter. See the KON-TR-01P User's guide.
• RFPGM – RF programmingTM (wireless upload). See the IQRF OS User's guide, Appendix RF programming.
