- I2C and pulse density modulation (PDM) audio interfaces
Description
Connected devices are constantly evolving. New generations appear that are smarter, more full-featured and have longer battery lifetimes. To enable this, SmartBond™ has evolved too. SmartBond 5.0 is smarter, more flexible, and even lower power. The DA14585 offers designers all the benefits of the industry-leading DA1458x but with even greater flexibility to create more advanced applications from the smallest footprints and power budgets.
As part of the SmartBond family, the DA14585 is one of the smallest, lowest power and most integrated Bluetooth® solutions available. This versatile system-on-chip (SoC) is ideal for adding Bluetooth Low Energy (LE) to products like remote controls, proximity tags, beacons, connected medical devices, and smart home nodes. It supports all Bluetooth developments up to Bluetooth 5. Plus, with 96kB of RAM, the DA14585 has double the memory for user applications of its predecessor to take full advantage of the standard's features. It also includes an integrated microphone interface for voice support at low additional cost. The wide supply voltage range (0.9V to 3.6V) covers a larger choice of energy sources and gives full design flexibility.
Like all SmartBond solutions, the DA14585 is easy to design-in and supports standalone as well as hosted applications. It is supported by a complete development environment and the SmartSnippets™ software that helps you optimize your software for power consumption.
