Dusseldorf, Germany, October 04, 2012 — Renesas Electronics Europe and Steinbeis Transfer Center Embedded Design and Networking (STZEDN) today announced the availability of a complete Wireless M-Bus 169MHz / 868Mhz solution to address the requirements of sub-metering applications in Europe. The Wireless M-Bus stack conforms to the specification EN 13757 and supports all specified modes (C, N, S1, S1-m, S2, T1, and T2 modes), as well as being extensively tested for interoperability with other solutions. On the application layer, it also supports Open Metering Specifications (OMS) v3 or Dutch Smart Meter Requirements (DSMR). OMS conformability is verified with the brand new OMS certification tool.


  Wireless M-Bus (Meter-Bus) is specified in EN 13757-4 and is specifically targeted for the remote reading of gas or electricity meters, as well as other low power meter applications.  The protocol’s characteristics are optimised to the requirements of battery operation, low data rate, robust communication and small stack footprint.


  The Wireless M-Bus stack offered by Renesas is available on its market leading RX and RL78 microcontroller (MCU) families, together with a choice of radio ICs. The solution includes not only the complete software stack, but also tools such as a Wireless M-Bus sniffer and PC based web surfer from Steinbeis for rapid evaluation and testing. Renesas is able to sub-license the Steinbeis WMBus stack as a library, together with low level drivers for the transceivers optimised both for RX and RL78 MCU families.


  Renesas is a market leader in providing MCU based solutions for the metering market with the RX 32bit MCU family offering the highest levels of performance and integration for metering system applications, whilst the RL78 MCU family of 16 bit devices is optimised for cost and lowest power consumption and is ideal for module and battery driven devices.


  Peter Kliegelhöfer, Senior Principal Engineer and Global Segment Marketing Leader of Renesas Electronics Europe commented: “I am delighted that Renesas and Steinbeis Transfer Centre have been able to join together to provide a full Wireless M-Bus solution for Renesas MCUs enabling customers designing Smart Meters and Smart Gateways to accelerate their time to market using MCUs and software from the market leaders.”


  Prof. Dr.-Ing. Axel Sikora, Director of Steinbeis Transfer Center adds: “For us, it is a great pleasure to see this very trustful and promising cooperation with Renesas on the way. We are confident that the market outreach of Renesas will also help our proven Wireless M-Bus stack solutions to find new customers and enable us to support these customers with our dedicated and highly experience design team.”


  At Metering Billing / CRM Europe, which takes place on 9-11 October at the RAI Convention Centre in Amsterdam (Netherlands), visitors can find out more about the Wireless M-Bus solution at the Renesas booth C35 (Hall 3).
