Applications: EBVchips

EBV presents some of the most exciting application examples for the smart grid market:



For communication in the context of ‘smart metering’, EBV Elektronik brought the EBVchip ‘Hermes’ onto the market, which sets new standards for M-bus communication

The new EBVchip is not only much cheaper than the IC, which has held the monopoly in the field of M-bus for around 20 years, but it also has technical advantages. Hermes, for example, needs much less energy and at the same time has a higher drive load and actively supports a low-power mode, which is particularly efficient in terms of wireless M-bus applications. The new EBVchip is designed to connect up to four programmable M-bus loads. Optionally, up to six M-bus loads can even be connected to the module, but this feature is not covered in the official M-bus standard. Here, the M-bus loads can be programmed using an external resistor. Also, the user data rate of Hermes is considerably higher than in the old M-bus module, because it is at 38.4 Kbps. A proven automotive process is used for the production of the new EBVchips, ensuring that maintenance is secured over a long period of time.

High quality, low power RF module in a compact form factor including an industry proven wireless M-Bus and OMS-layer to OMS 3.X and OMS 4.X specifications

Maia is a single embedded low cost wireless M-Bus RF Module developed specially for the AMR (Automatic Meter Reading) smart metering and smart grid infrastructure where the Wireless M-Bus standard (EN13757-4) and OMS standards are used.
Its high quality, small form factor: 15mm x 14mm makes it ideal for SMD assembly. The module offers low power consumption which is achieved with STM’s ultra-low power microcontroller STM 32L05 and SPIRIT1, the low power Sub-GHz data rate transceiver. Also on board is an ultra-miniature balun, BALF-SPI-01D3 matching SPIRIT1 and supporting the connection to an external antenna, therefore saving space and cost.
In addition, Maia includes an industry proven wireless M-Bus and OMS-layer to OMS 3.X and OMS 4.X specifications. As the user can integrate their region-specific application layer there is no need for an external host controller. The module is also pre-certified and conforms to EUR & TTE directives.

Vulcanus is a compact surface-mounted Wireless M-Bus module featuring an RF front-end and a MCU with embedded wireless M-Bus protocol software supporting the new EN13757 – 4:2013 Mode N and is pre-certified for operation under EU radio regulations

The Vulcanus module measures only 15 x 34 x 3.8 mm and contains a communication engine with embedded Wireless M- Bus protocol software, a high performance RF transceiver and an amplifier. The communication engine handles the radio packet protocol, the UART interface and controls the RF transceiver as well as the external IOs. The external host processor will manage the module configuration by sending ‘AT’ commands to the communication engine via UART allowing configuring frequency, channels, output power, GPIO behavior etc. The commands are used to start and stop the communication as well as to put the module in deep sleep to achieve ultra-low powerconsumption while the module is not used . Some configuration parameters are stored in the internal non-volatile memory in order to be restored by a power-up sequence. The module has an advanced filtering circuitry to suppress harmonics and spurs.
