TR-62D Transceiver Module for Wireless M-Bus Data Sheet Preliminary © 2013 MICRORISC s.r.o. www.iqrf.org DSTR62D_130607 Page 1 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. Key features Applications • Embedded Wireless M-Bus protocol, without operating system • Wireless M-Bus • Wireless M-Bus EN 13757-4:2005 modes S1, T1, S2 and T2 • Telemetry • UART ↔ Wireless M-Bus converter • Automated meter reading (AMR) • UART pins: RX, TX • Heat, electricity, gas and water meters • FSK modulation • RF band 868 MHz • RF output power up to 7 mW • Extra low power consumption • +3 V LDO regulator output • 2 LEDs • Options: on-board antenna, U.FL connector • SIM card format Block diagram © 2013 MICRORISC s.r.o. www.iqrf.org DSTR62D_130607 Page 2 TR-62D Information contained in this publication regarding device applications and the like is provided only for your convenience and may be superseded by updates.

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. Operating temperature 1 Supply current Sleep mode Run mode -40 °C to +85 °C 1 µA (Pin C8 must be at logic high level) 6.2 mA Rx mode 19 mA (RF IC in Rx mode, MCU in sleep mode) Tx mode 36 mA (RF IC in TX mode, 13 dBm, MCU in run mode) Nominal frequency RF data modulation RF data transmission bit rate 868.30 and 868.95 MHz FSK (Frequency Shift Keying) 32.768 kb/s (mode S) 100 kb/s (mode T) RF sensitivity -98.8 dBm RF output power 8.5 dBm (mode T), 6.7 dBm (mode S) 2 RF range (TR-62DA) Up to 315 m (mode T), 245 m (mode S) Input voltage on C5 and C8 pins 0 V to VOUT Size (L x W x H) 25.0 mm x 14.9 mm x 3.0 mm (TR-62D) 31.8 mm x 14.9 mm x 3.0 mm (TR-62DA) 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.
