Protocol Based Transceivers


The 32001324 is a Wireless M-Bus transceiver operating in the 868 MHz SRD Band. Thanks to its small LLC form factor (15 x 25 mm only) and its low power consumption this module allows the implementation of highly integrated low power (battery operated) solutions for water, gas, heat or electricity metering applications, both on meter or concentrator devices.

The module supports various operating modes (S, T, R, C) to meet the requirements of one-way and two-way data communication, in stationary and mobile systems.

The embedded stack implemented according to EN13757-4 Standard provides the physical access to the Wireless M-Bus communication.

SPI and UART allow integration flexibility and easy development of customer products.

The module meets all the requirements in the industrial temperature range -40/+85°C.

The module is certified according to R&TTED 1999/05/EC and is compliant with the REACH And RoHS directives.

Evaluation kit

All features of the W-M BUS transceiver can be tested with dedicated evaluation kit (PN 33000151). The board provides easy access to module pin out, power supply pins and SMA antenna connector; usage flexibility is given by several power supply modes. To reduce the time to market and ease the user application SW development, the Evaluation Kit comes with a built in microcontroller. Access pins on the board allow SW development to be managed by an external microcontroller and custom SW development.
