ZigBee / 15.4 / RF4CE Low Cost SoC

OverviewFeaturesRequest Datasheet
The  Zigbee/15.4/RF4CE SoC solution with internal Flash support. It supports IEEE 802.15.4 standard and Zigbee-compliant platform. The 8656 solution can be used for a wide range of applications and is perfect for creating interoperable solution for use within the home combined with our leading Zigbee/RF4CE software stack. The 8656 supports single or dual analog MIC or digital microphone, and stereo audio output with enhanced voice performance for voice search and other such applications. The 8656’s embedded 512kB FLASH enables dynamic stack and profile configurations and has hardware OTA upgrades support and multiple booth switching.The 8656 also include a full range of on-chip peripherals for interfacing with external components such as LED’s sensor touch controllers, keyboards and mice. This make it a ideal single chip solution for Zigbee/IEE 802.15.4/RF4CE applications for smart home. ZigBee-15.4-RF4CE-Low-Cost-SoC-supplier-in-europe
