CSR102X, a new Bluetooth® Smart 4.2 System-on-Chip (SoC) family specifically designed to help engineers meet the needs of today’s “always-on” world. The CSR102x family is optimized for specific applications in the Internet of Things (IoT), including wireless remote controls, simple smart watches, home automation solutions and beacons, where balancing performance, battery life and cost is critical.
Balancing power, features and cost, optimized for specific use cases and target applications, is not easy but the new CSR102x family of SoCs brings extensive and flexible I/O capabilities designed to simplify integration and eliminate expensive interface components.
A comprehensive software development kit enables developers to get ahead with example applications such as Bluetooth Smart profiles and smartphone apps, all in source code. A secure, over-the-air update (OTAU ) capability enables flash-based product family members to be reliably updated while in service. Other features that have been added to address target use cases includes high quality voice command capabilities with ultra-low power, for remote controls with always-on voice and CSRmesh™ support for home automation manufacturers looking to create whole home systems.

Much of the Low Power capabilities of the CSR120X family can be rewarded to the efficient 16 –bit RISC controller being used and also to the Hardware Link Controller, which let the chip stay in sleep much longer periods than conventional solutions and thus saving power.
There are development kits available today, both for general IoT applications, as well as for more specific use cases like a Smart Remote Control Development Board and a Smart Watch Development Board.
