The AMB9626 is a compact, low-cost and low power 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 address switching. It also implements
asynchronous frequency hopping techniques in order to
comply with FCC 15.247. 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 AMB9626 to a PC system.
The AMB9626 is an SMT device and is suitable for
automatic component assembly. It can also be delivered in
tape and reel packaging.
The AMB9626 is connected to a host system via the
UART interface with data rates of up to 19200 kBaud.
Other pins are used for data flow control and to switch
between operating modes.
Using appropriate firmware, the module is also suitable
for autonomously recording digital or analogue signals.
The receiving module is scanning all available channels
for active transmitters while the transmitter is randomly
selecting a transmission channel for each frame.
With the channel scanning a latency is introduced which
has to be taken into account regarding the duty-cycle of
the system.
The main focus of the AMB9626 is spontaneous data
transmission with limited amount of data and a duty-
cycle of 10% or less.
The AMB9626 implements a low power operating mode
where µC and UART are disabled to have a current
below 3 µA.
