SNAP Engine SM220 Modules Overview

The 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 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 battery-

driven 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.
