The EM260 from Ember is a ZigBee Standard Network Co-Processor that combines a 2.4GHz IEEE 802.15.4 compliant radio transceiver with a flash-based microprocessor running the EmberZNet ZigBee stack. With a fast SPI/UART based interface to an application microprocessor, the EM260 allows developers to easily add ZigBee networking to their favorite microcontroller. The EM260 handles all of the timing critical and resource intensive ZigBee networking stack, allowing the application microprocessor to focus solely on application requirements. The radio in the EM260 provides best-in-class RF performance with excellent sensitivity and transmit power for long range, and 802.11 immunity. A flexible RF interface minimizes external components in configurations with or without external LNA/PAs.
