Zigbee and 802.15.4 Networking

The EM250 from Ember provides a true ZigBee System-on-Chip that combines a 2.4GHz IEEE 802.15.4 compliant radio transceiver with a powerful, efficient industry proven 16-bit microprocessor with comprehensive hardware supported network-level debugging features to simplify development.
Designed specifically for use with EmberZNet, Ember’s ZigBee compliant embedded mesh networking software, the EM250 is optimized for designs requiring long battery life, low external component count, and a reliable, proven, industry-standard networking solution.   Parts List

The EM260 from Ember is the first network co-processor chip that has been designed for the low power, low cost, mesh networking industry standards based protocol – ZigBee. The EM260 is designed to provide customers the flexibility of choosing their own microcontroller to run their application, while interfacing to the EM260 to provide all the ZigBee functionality. The external microcontroller can be sized exactly for the application, from the smallest, most cost-effective 8-bit controller, all the way through high-end 32-bit controllers for gateway applications. This flexibility of microcontroller choice allows customers to ZigBee enable existing products very rapidly using tool-chains they are familiar with.
