SNAP Engine RF220SU Module Overview
The SNAP Engine Model RF220SU is an IEEE 802.15.4, low-power,
highly reliable solution for embedded wireless control and monitoring
networks.
The RF220SU 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. This low-cost
module can have current consumption under 390nA to enable a new
generation of battery-driven systems.
The RF220SU 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. The
modules provide up to 15 channels of operation in the ISM 2.4GHz frequency band.
By default, the SNAP operating system automatically forms a mesh network with other nodes immediately on
receiving power. No further configuration is necessary. Multiple unrelated SNAP networks can exist within the same
area through several configuration options outlined in the SNAP User Guide available from www.synapsewireless.com.
NOTE: Channel 15 is receive-only due to FCC power restrictions.

1 Absolute maximum stress rated voltage for VCC is -0.3 to 3.6. It is recommended that bulk capacitance be located as close as possible
to the VCC pin on the host board. Ideally, use a single 47µF capacitor rated at 10V directly at the VCC pin.
2 VREFH is programmable to three fixed values; 1.5V, 1.6V, and 1.8V. The VREFH value will be 1.6 volts if you do not explicitly adjust it
by poking the ATmega128RFA1 registers.
3 Each differential analog input may be as high as 3.3V but the single-ended voltage is still limited to the voltage reference.
Mechanical Drawings
RF220SUMechanical Drawing on page 7. and Block diagram showing the major subsystems comprising Model
RF220SU on page 8. are for modules with the compact F antenna and U.FL Connector options.
Figure 1: RF220SUMechanical Drawing
NOTE: The area under the module's antenna (marked KEEP OUT AREA) should have no components, no traces,
and no copper on any layer of the printed circuit board.
Figure 2: Block diagram showing the major subsystems comprising Model RF220SU
Selecting an Antenna
The RF220SU uses the RP-SMA connector by default. If you wish to use an external U.FL antenna with your
application, you will need to set bit 0x0010 of NV ID 64 to 1 and reboot your node. This is a one-time change that will
persist through reboots and program changes. To revert to the RP-SMA antenna, change bit 0x0010 of NV ID 64
back to 0 and reboot the node.
Antenna Gain Performance
NOTE: Antenna gain performance information is based on information from the individual companies at the time
this document's release. For added assurance, it's best to obtain antenna performance information directly from
that antenna's manufacturer.
NOTE: A u.fl to SMA cable is included for use of the u.fl port.
