DRAFT COPYGenerated on 9/16/2014SNAP Engine SM220 Modules OverviewThe SNAP Engine Model SM220 series currently consists of the SM220UF1. It is an IEEE 802.15.4,low-power, highly reliable solution for embedded wireless control and monitoring networks thatrequire high data rates. The Model SM220 embeds Synapse’s SNAP OS, the industry’s firstInternet-enabled, wireless mesh network operating system, into the Atmel ATmega128RFA1single-chip AVR®microcontroller with an integrated transceiver that delivers up to 2Mbits/sec. Thislow-cost module can have current consumption under 390nA to enable a new generation of battery-driven systems. The SM220 also includes a Skyworks SE2431L front-end module, which provides apower amplifier and LNAfor increased range.SNAP’s on-board Python interpreter provides for rapid application development and over-the-airprogramming, while Atmel’s low-power RF single-chip design saves board space and lowers powerconsumption. The modules provide up to 15 channels of operation in the ISM 2.4GHz frequencyband.This data sheet covers part number SM220UF1:• 36 GPIO with up to 7 A/D inputs• 128k flash, 58.5k free for over-the-air uploaded user apps• Two UART ports for control or transparent data• Low power modes:• Timed Sleep Mode 1: 1.27 µA• Timed Sleep Mode 2 : 1.47 µA• Untimed Sleep Mode : < 390 nA• Spread Spectrum (DSSS) technology• Up to 2 Mbps radio data rate• 2.4 GHz RF Frequency• AES 128-bit encryption• Integrated compact F antenna or U.FL connecter• Surface Mount, Solder-able• 4K internal EEPROM• 8 PWM outputs1SNAP Engine SM220 Series Data Sheet — 430000-01A

If you wish to use an external U.FLantenna with your application, you will need to set bit 0x0010 of NV ID 64 to 1. This is a one-timechange that will persist through reboots and program changes. To revert to the internal antenna,change bit 0x0010 of NV ID 64 back to 0.Antenna Gain PerformanceHyperLink Technologies HG2405RD-RSPFigure 3: HyperLink Technologies HG2405RD-RSP Antenna Gain Performance

DRAFT COPYGenerated on 9/16/2014• Cleaning with alcohol or a similar organic solvent will likely flood soldering flux residuals intothe two housings, which is not accessible for post-washing inspection. The solvent couldalso damage any stickers or labels.• Ultrasonic cleaning could damage the module permanently.The recommended approach is to consider using a “no clean” soldering paste and eliminate thepost-soldering cleaning step.Repeating Reflow SolderingOnly a single reflow soldering process is encouraged for host boards.ReworkThe Model SM220 Module can be unsoldered from the host board, but the process is likely todamage the chip and not recommended. If attempting this, use of a hot air rework tool and hot platefor pre-heating from underneath is recommended. Avoid overheating.WARNING!: Never attempt a rework on the module itself (e.g. replacing individualcomponents). Such actions will terminate warranty coverage.Additional GroundingAttempts to improve module or system grounding by soldering braids, wires, or cables onto themodule RF shield cover is done at the customers own risk. The numerous ground pins at the moduleperimeter should be sufficient for optimum immunity to external RF interference.11SNAP Engine SM220 Series Data Sheet — 430000-01A
