The low cost Zigbee to Ethernet Gateway reference design is a turn-key production-ready solution that connects IEEE 802.15.4 wireless networks to wired Ethernet networks. For the Zigbee, Atmel ATmega256RFR2 is used and WIZnet W5200 is used for Ethernet connectivity.
The Atmel ATmega256RFR2 wireless system-on-a-chip (SoC) combines best-in-class radio performance with the efficient Atmel AVR® 8-bit CPU.
The WIZnet W5200 embedded Ethernet controller features a10BaseT/100BaseTX MAC and PHY and supports many popular Ethernet protocols including TCP/IP, UDP and IPv4. The wired Ethernet interface is a low-cost, reliable and secure connection that works with the end user’s existing routers, access-points, WLANs and ISPs. Wired Ethernet lowers cost and also avoids interference problems
and regulatory issues inherent with co-located radio solutions. This reference design was developed with low BOM cost as a primary objective.
