AMB3626-M www.amber-wireless.de Compact Low-Cost Radio Module 169 MHz Band Key Features Low-cost OEM radio module for the 169 MHz SRD band Supporting wireless M-BUS N-Modes (N1a to N1f, N2a to N2g*) Compact dimensions: 17 x 27 x 4 mm Supports low-power applications and WOR (wake-on radio) Integrated wireless M-BUS stack with extensive functions Complies with requirements of EN13757-4 Tape & Reel packaging for automatic component placement 1 Pin-Compatible to AMB8426-M & AMB8626-M Description The Wireless M-Bus standard (EN13757-4) specifies the communication between water, gas, heat and electricity meters and concentrators. The standard comprises various operating modes (S, T, R and N) to meet the requirements of one-way and two-way data communication in stationary and mobile systems. The AMB3626-M is an all embedded low-cost wireless M-Bus radio module, which operates in the 169 MHz frequency band (supporting Modes N1a to N1f and N2a to N2g*). The integrated protocol controls the entire data communication. Data packets are built and transmitted according to EN13757-4 specification. Configuration of parameters is handled via the UART interface. The module automatically adds the Manufacturer ID and the Address based on parameters configured in the radio module. Measured field strength (RSSI value) offers the option of enhancing quality of the radio link. (*N2g on request) The customised application layer can be fully integrated in the radio module, thus eliminating the need for an external host microcontroller. The radio module supports the AES-128 encryption standard. A very low-power mode ensures long battery lifetime. The graphical user interface of the freely available Windows application AMBER-ACC makes it easy to set operating parameters. A USB stick version is available to easily connect the AMB3626-M to a PC system. The module is pre-certified for operation under the European radio regulations for license-free use. The AMB3626-M is a surface-mounted module and is available on Tape &Reel for volume production. Interfaces The AMB3626-M is connected to a host system via the UART interface with bit rates of up to 115.2 kbaud. Other pins are used for data flow control and to switch between operating modes. An SPI interface is optionally available (separate firmware). Using appropriate firmware, the module is also suitable for autonomously recording digital or analogue signals. Range of Application The radio module is designed for automatic meter reading applications for wireless data transmission according to the Wireless M-Bus specification (EN13757-4). The radio module is designed to be integrated in meters, concentrators and mobile metering devices. Other applications are conceivable. Its compact dimensions and low-power consumption make the radio module ideal for battery-powered devices. 1 Variation in programming Pins.
