SN260
1 General description
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 ZigBee-compliant network stack. The
SN260 exposes access to the EmberZNet API across a standard SPI module, allowing
application development on a Host processor. This means that the SN260 can be viewed as
a ZigBee peripheral connected over a SPI. 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 draws 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.
Target applications for the SN260 include:
● Building automation and control
● Home automation and control
● Home entertainment control
● Asset tracking
The SN260 can only be purchased with the EmberZNet stack. This technical datasheet
details the SN260 features available to customers using it with the EmberZNet stack.
