Irvine-based RFaxis, the developer of wireless semiconductors, reports a design win this morning with GreenPeak Technologies, a developer of smart home and home automation chipsets. RFaxis said that GreenPeak has incorporated its ZIgBee/ISM RF Front End IC (RFeIC) to tie together with its own, ZigBee systems-on-a-chip. The two are delivering a reference design for developers using their respective technology. The RFaxis chip provides all of the RF functions needed to support IEEE 802.15.4/ZigBee, as well as other wirelss systems using the 2.4GHz ISM band. GreenPeak's chips are used by manufacturers of home automation gateways, home security, home healthcare, set-top boxes, lighting control, and smart energy products.
