EBVchip til smart meter applikationer

Som et led i det såkaldte EBVchips program har EBV i samarbejde med WEPTECH og STMicroelectronics udviklet Maia, der er et sub-GHz RF-modul til wireless M-BUS OMS applikationer.

EBV Elektronik and WEPTECH elektronik has worked closely with STMicroelectronics to develop a flexible sub-GHz RF module that streamlines certification of wireless M-BUS and OMS metering systems.

The module, called MAIA within the EBVchips program, addresses different metering applications, including automatic meter reading (AMR), advanced metering infrastructure (AMI), gas and water meters, and electricity meters, as well as heat meters or readers and concentrators.

The RF module, which will be released in a compact form factor (15mm x 14mm) suitable for SMT assembly, features an STM32L0 ultra-low-power microcontroller, a low-power SPIRIT1 sub-GHz transceiver, and BALF-SPI-01D3 Balun. In addition, the module incorporates the wireless M-Bus and OMS-layer to OMS 3.X and OMS 4.X specifications and supports connection to an external antenna. The module will be pre-certified and CE conforming.

- The module provides easy and quick integration of an OMS interface in meter or smart meter gateways, enabling – in fact, encouraging – fast time-to-market with the OMS interface, says Wolfgang Esch, WEPTECH elektronik and member of the board of the OMS group.

- With very tight performance and power budgets, WEPTECH electronic and EBV Elektronik made good choices in our ultra-low-power microcontroller STM32L0 and our low-power sub-GHz transceiver for the module, as it offers the best solution for a wide range of metering applications in EMEA, adds Dr. Bernhard Rauscher, Vice President Applications, EMEA Region, STMicroelectronics.

Dr. Eckart Voskamp, Director EBVchips Program EBV Elektronik concludes:
- With our second device for the smart metering market within the EBVchips program we are addressing the growing market demand within the IoT application space. This device combines the best in class hardware solution with the leading and industry proven software stacks.
