It is an IEEE 802.15.4, low-power, highly reliable solution for embedded wireless control and monitoring networks that require high data rates. The Model SM220 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 batterydriven systems. The SM220 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. The modules provide up to 15 channels of operation in the ISM 2.4GHz frequency band. 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 outputs er en AF • • • • This data sheet covers part number SM220UF1: at on SNAP Engine SM220 Series Data Sheet — 430000-01A PY 01 /2 16 9/ ed • • • • • • • • Specifications Table 1: SM220 Specifications at 23° C and 3.3V unless otherwise noted Outdoor LOS Range 3 miles Performance Transmit Power Output up to +20 dBm RF Data Rate 250Kbps, 500Kbps, 1Mbps, 2Mbps Receiver Sensitivity -103 dBm (1% PER, 250Kbps) Supply Voltage 2.0 - 3.6 V Transmit Current (Typ@3.3V) at +20 dBm: 150 mA at +6 dBm: 55 mA Idle/Receive On Power (Typ@3.3V) Requirements Idle/Receive Off (Typ@3.3V) 22 mA 7.8 mA Timed Sleep: 1.27 µA Untimed Sleep Mode : 390 nA Frequency ISM 2.4 GHz Sleep Mode Current (Typ@3.3V) AF Direct Sequence (DSSS) Modulation O-QPSK Dimensions en General Spreading Method 29.8mm x 19mm er - 40 to 85 deg C. at Operating Temperature on Networking Error Handling Number of Channels UARTS with optional HW Available I/O Flow Control Agency Approvals SNAP PY Topology 3 grams 01 /2 16 9/ Weight U.FL and Internal F ed Antenna Options Retries and acknowledgement 15 fully operational channels, and channel 15 operates in a receive only state 2 Ports GPIO 36 total; 7 can be analog-in with 10bit ADC FCC Part 15.247 FCC ID: U9O-SM220 Industry Canada (IC) 7084A-SM220 CE Certified Certified to EN300 328 Version 1.8.1 SNAP Engine SM220 Series Data Sheet — 430000-01A SM220 Module Pin Definitions For pin locations, consult the SM220 Mechanical drawing later in this document.

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.

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. This is a one-time change that will persist through reboots and program changes. To revert to the internal antenna, change bit 0x0010 of NV ID 64 back to 0. at on ed Antenna Gain Performance PY 01 /2 16 9/ HyperLink Technologies HG2405RD-RSP Figure 3: HyperLink Technologies HG2405RD-RSP Antenna Gain Performance SNAP Engine SM220 Series Data Sheet — 430000-01A Pulse W107 AF er en at on ed Board Mounting Considerations Processing Table 5: Recommended Reflow Profile Parameter PY 01 /2 16 9/ Figure 4: Pulse W107 Antenna Gain Performance Value Ramp up rate (from Tsoakmax to Tpeak) 3º/sec max Minimum Soak Temperature 150ºC Maximum Soak Temperature 200ºC Soak Time 60-120 sec SNAP Engine SM220 Series Data Sheet — 430000-01A Parameter Value TLiquidus 217ºC Time above TL 30-60 sec (recommended: 40 sec) Tpeak 230º - 250ºC (recommended: 235ºC) Time within 5º of Tpeak 20-30 sec Time from 25º to Tpeak 8 min max Ramp down rate 6ºC/sec max AF er en at on PY 01 /2 16 9/ Pb-Free Soldering Paste ed Figure 5: Reflow Profile Graph Use of “No Clean” soldering paste is strongly recommended, as it does not require cleaning after the soldering process. Cleaning In general, cleaning the populated modules is strongly discouraged. Residuals under the module cannot be easily removed with any cleaning process. • 10 Cleaning with water can lead to capillary effects where water is absorbed into the gap between the host board and the module. The combination of soldering flux residuals and encapsulated water could lead to short circuits between neighboring pads. Water could also damage any stickers or labels. SNAP Engine SM220 Series Data Sheet — 430000-01A • • Cleaning with alcohol or a similar organic solvent will likely flood soldering flux residuals into the two housings, which is not accessible for post-washing inspection. The solvent could also 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 the post-soldering cleaning step. Repeating Reflow Soldering Only a single reflow soldering process is encouraged for host boards. Rework The Model SM220 Module can be unsoldered from the host board, but the process is likely to damage the chip and not recommended. If attempting this, use of a hot air rework tool and hot plate for pre-heating from underneath is recommended. Avoid overheating. WARNING!: Never attempt a rework on the module itself (e.g. replacing individual components). Such actions will terminate warranty coverage. Additional Grounding AF Attempts to improve module or system grounding by soldering braids, wires, or cables onto the module RF shield cover is done at the customers own risk. The numerous ground pins at the module perimeter should be sufficient for optimum immunity to external RF interference. er en at on PY 01 /2 16 9/ ed SNAP Engine SM220 Series Data Sheet — 430000-01A 11 Agency Certifications United States (FCC) The Model SM220 modules comply with Part 15 of the FCC rules and regulations.
