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.

Features

■ Integrated 2.4GHz, IEEE 802.15.4-compliant transceiver:

– Robust RX filtering allows co-existence with IEEE 802.11g and Bluetooth devices

– - 97.5dBm RX sensitivity (1 PER, 20byte packet)

– + 3dBm nominal output power

– Increased radio performance mode (boost mode) gives –98.5dBm sensitivity and +5dBm transmit power

– Integrated VCO and loop filter

– Secondary TX-only RF port for applications requiring external PA.

■ Integrated IEEE 802.15.4 PHY and MAC

■ Dedicated peripherals and integrated memory

■ EmberZNet™ ZigBee®-compliant stack running on the dedicated network processor

■ Controlled by the Host using the EmberZNet™ Serial Protocol (EZSP)
