AMB8626 Compact Radio Module - High Performance 868 MHz SRD Band Key Features Low-cost OEM radio module for the 868 MHz SRD band Compact dimensions: 17 x 27 x 4 mm Supports low-power applications and WOR (wake-on radio) Integrated AMBER RF stack with extensive functions Flexible addressing with up to 255 nodes in 255 networks Conforms with EU R&TTE 1999/5/EC directive Available on Tape & Reel for SMT assembly Also available as wireless USB adapter (AMB8665) Compatible to AMB8426, enhanced radio chipset radio and 1 microprocessor Network Topologies Description The AMB8626 is a compact and low-cost radio data transmission module for wireless half-duplex communication. The integrated microprocessor controls data communication, handling packet and checksum generation, addressing, monitoring of channel access and re-transmission of lost packets. The host system does not have to perform any radio-specific tasks. The module can be configured in many ways and supports data transfer with fast channel and address switching. An opportunity to assess the quality of the radio link is also provided by using the measured field strength (RSSI value). 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 AMB8626 to a PC system. Star The AMB8426 is designed as a SMT device and is suitable for automatic component assembly. It can also be delivered in tape and reel packaging. Interfaces The AMB8626 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. Peer-to-Peer Range of Application Data collection, monitoring, remote control and sensor networks. Its compact dimensions and low power consumption make the radio module ideal for battery-powered devices. 1 Migration guide avaiable upon request AMB8626 Dimensions Pin Assignment No. Pad Name I/O 1 ANTENNA - Antenna connection 2,23 GND - Ground 3 VCC - Positive supply voltage 4 UTXD O UART transmit 5 URXD I UART receive 6 /RTS 0 Flow control 7 /CTS I Flow control 8 /DATA_INDICATE O Signals incoming data 11 /DATA_REQUEST I Triggers packet transmission 13 SLEEP I Selection of low-power mode 14 TRX_DISABLE I Selection of low-power mode 15 /CONFIG I Switches to command mode 19 /RESET I Reset 20 RX_INDICATE O Signals radio reception 21 TX_INDICATE O Signals radio transmission RSVD - Reserved (do not connect) 9,10,12,16,17,18, 22 Description Specifications TA = 25C, VCC = 3.3 V if nothing else stated Performance General RF technology Conformity Range* Up to 2000 m RF data rate Up to 250 kbps (Gross) Interface data rate Up to 115.2 kbps (UART) Output power Up to 14 dBm (50 ) RF sensitivity Down to -123 dBm (50 ) Power supply 2.0 - 3.6 V Power consumption - Dimensions 17 x 27 x 4 mm Operating temperature -30 to +85 C Weight Approx. 3 g Antenna External antenna port (50 ) Microprocessor MSP430 Addressing Up to 255 nodes on 255 networks Frequency range 865.0 - 870.0 MHz Channel spacing 50 kHz Modulation 2-(G)FSK, (G)MSK, 4-(G)FSK Supported topologies Star, Peer-to-Peer Europe EN 300 220, EN 301 489, EN 60950, EN 50371 TX: typ. 53 mA RX: typ. 30 mA Low Power: typ. 3 A * Range stated assumes line-of-sight.
