Section 6 describing the ASH protocol has been moved to document UG101, UART Gateway Protocol Reference. Section 7 on EZSP has been moved to document UG100, EZSP Reference Guide. The EM260 integrates a 2.4GHz, IEEE 802.15.4-compliant transceiver with a 16-bit network processor (XAP2b core) to run EmberZNet PRO, Silicon Labs ZigBee-compliant network stack. The EM260 exposes access to the EmberZNet PRO API across a standard SPI module or a UART module, allowing application development on a Host platform. This means that the EM260 can be viewed as a ZigBee peripheral connected over a serial interface. The XAP2b microprocessor is a power-optimized core integrated in the EM260. It contains integrated Flash and RAM memory along with an optimized peripheral set to enhance the operation of the network stack. The transceiver utilizes an efficient architecture that exceeds the dynamic range requirements imposed by the IEEE 802.15.4-2003 standard by over 15dB. The integrated receive channel filtering allows for co-existence with other communication standards in the 2.4GHz spectrum such as IEEE 802.11g and Bluetooth. The integrated regulator, VCO, loop filter, and power amplifier keep the external component count low. An optional high-performance radio mode (boost mode) is software selectable to boost dynamic range by a further 3dB. The EM260 contains embedded Flash and integrated RAM for program and data storage. By employing an effective wear-leveling algorithm, the stack optimizes the lifetime of the embedded Flash, and affords the application the ability to configure stack and application tokens within the EM260. To maintain the strict timing requirements imposed by ZigBee and the IEEE 802.15.4-2003 standard, the EM260 integrates a number of MAC functions into the hardware. The MAC hardware handles automatic ACK transmission and reception, automatic backoff delay, and clear channel assessment for transmission, as well as automatic filtering of received packets. In addition, the EM260 allows for true MAC level debugging by integrating the Packet Trace Interface. An integrated voltage regulator, power-on-reset circuitry, sleep timer, and low-power sleep modes are available. The deep sleep and power down modes draw less than 1 A, allowing products to achieve long battery life. Finally, the EM260 utilizes the non-intrusive SIF module for powerful software debugging and programming of the network processor. Target applications for the EM260 include: Building automation and control Home automation and control Home entertainment control Asset tracking The EM260 can only be purchased with the EmberZNet PRO stack. This technical datasheet details the EM260 features available to customers using it with the EmberZNet PRO stack. 120-0260-000M Rev 1.1 Page 2
