Skyworks Solutions, innovators of high performance analogue and mixed signal semiconductors, and Ember, providers of ZigBee technology solutions, have announced that they are partnering to develop the industry's first portfolio of ZigBee front-end modules (FEM), targeting applications such as smart metres in energy management, home area networks (HAN) and industrial automation. ZigBee is a wireless network standard that solves the needs of remote monitoring, control and sensor-network applications. Caelera distribute analogue and mixed signal semiconductors designed by Skyworks Solutions.
Ember's EM250 system-on-chip (SoC), along with the EmberZNet PRO networking stack, is an SoC platform supporting the ZigBee PRO Feature Set. The EM250 integrates an IEEE 802.15.4 radio, a 16-bit microprocessor, flash, random access memory (RAM) and peripherals.
Ember's EM260 is a ZigBee network co-processor that combines a 2.4 gigahertz (GHz) IEEE 802.15.4 compliant radio transceiver with a flash-based microprocessor running the EmberZNet PRO ZigBee stack. The EM260 allows developers to add ZigBee networking to their preferred application microprocessor via a fast SPI/UART interface.
The EM250 and EM260 chips are tightly integrated with EmberZNet PRO and are optimised for designs that require long battery life and low external component count.
The SKY65336 is a high efficiency 8 x 8 millimetre multi-chip module (MCM) FEM for ZigBee and other 2.4 GHz industrial, scientific and medical (ISM) band applications. The FEM comprises a selectable transmit and receive (Tx/Rx) path. The Tx path incorporates a harmonic filter and high efficiency PA which delivers 20 dBm at the module's output port. The Rx path includes a low noise amplifier (LNA). Both the Tx and Rx paths integrate baluns to provide differential ports to Ember's EM250 and EM260 transceivers.
The SKY65337 is footprint compatible with the SKY65336, with the LNA removed for applications which require lower cost.
