Product Information

Back to top
The EM260 integrates a 2.4GHz, IEEE 802.15.4-compliant transceiver with a 16-bit network processor (XAP2b core) to run EmberZNet PRO, Silicon Labs’ ZigBee-compliant network stack. The EM260 exposes access to the EmberZNet PRO 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.

Symmetry Electronics is an authorized Silicon Labs distributor.
