“Our new development kit lowers the barriers for smart home device development,” says Sean McGrath, SVP and GM Connectivity Business Group, Dialog Semiconductor. “Beyond the simplicity of the highly integrated connectivity SoC at the heart of the kit, its fastest response times create the best possible user experience for end devices, with initial pairing taking less than 2.8 seconds and responding faster than 250 ms whenever an iOS device issues a command. This creates an instant response whenever a user interacts with a HomeKit-powered light, door lock, smoke detector or other accessory.”
The SmartBond DA14681 supports Bluetooth 4.2 to provide seamless connectivity, and smartly balances power efficiency and performance, with an integrated ARM Cortex M0 processor and expandable flash memory. A Power Management Unit (PMU) provides three independent power rails, in addition to an on-chip charger and fuel gauge, allowing DA14681 to recharge batteries over a USB interface.
Its integrated topology streamlines development, minimizes BOM cost and enables the kit to consume less than five µA on standby. The development kit maximizes application space and flexibility, using a mere 170 kB of Flash memory and provides 64 kB of RAM for apps to utilize, even allowing user defined profiles to further customize applications on top of pre- configured HomeKit profiles.
To give developers all of the tools they need to create next-generation IoT applications, the DA14681 development kit consists of the HomeKit SDK, Basic and Pro versions of the kit, and a flexible add-on board to interface with the separately available MFi chip. The new HomeKit development kit and add-on board are now available from Avnet, Digi-Key and Mouser.
