EM260
General Description
120-0260-000J
The EM260 integrates a 2.4GHz, IEEE 802.15.4-compliant transceiver with a 16-bit network processor (XAP2b
core) to run EmberZNet, the Ember ZigBee-compliant network stack. The EM260 exposes access to the
EmberZNet 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 1μA, 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:

The EM260 can only be purchased with the EmberZNet stack. This technical datasheet details the EM260
features available to customers using it with the EmberZNet stack.
