General description
The SN260 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 SN260 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
SN260 can be viewed as a ZigBee peripheral connected over a serial interface. The XAP2b
microprocessor is a power-optimized core integrated in the SN260. 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 SN260 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 SN260.
To maintain the strict timing requirements imposed by ZigBee and the IEEE 802.15.4-2003
standard, the SN260 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 SN260 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 µA, allowing
products to achieve long battery life.
Finally, the SN260 utilizes the non-intrusive SIF module for powerful software debugging
and programming of the network processor.
