Synapse RF220
Models RF220UF1, RF220SU, and RF220SU-EU
All the power of the SM220 in
a modular form
The SNAP Module Model RF220 series is an IEEE 802.15.4, low-power,
highly reliable solution for embedded wireless control and monitoring
networks that require great range and low power.
When time to market is critical, the modular format of the RF220 makes
prototyping and testing easy. Later, when the design is in the field, module
swaps and upgrades are just as fast thanks to the common footprint.
The RF220 model embeds Synapse’s SNAP OS, the industry’s first
Internet-enabled, wireless mesh network operating system, into the Atmel
ATmega128RFA1 single-chip AVR® microcontroller with an integrated
transceiver that delivers up to 2Mbits/sec in up to 15 channels of operation
in the ISM 2.4GHz frequency band. This low-cost module enables a new
generation of battery-driven systems with current consumptions as low as
390nA. The RF220 also includes a Skyworks SE2431L front-end module,
which provides a power amplifier and LNAfor increased range.
SNAP’s on-board Python interpreter provides for rapid application
development and over-the-air programming, while Atmel’s low-power RF
single-chip design saves board space and lowers power consumption.
