SN260 Datasheet PDF - STMicroelectronics

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.
