Qualcomm CSR1012A05-IQQP-R

The CSR101x product family consists of five product variants designed to develop devices that use Bluetooth low energy. The CSR101x series provides a built-in processor to run the customer application as well as the qualified Bluetooth single mode stack and radio. CSR101x chips can run directly from a 3V coin cell, and connect directly to a PCB antenna. The CSR101x System-on-Chips (SoCs) are optimized for easy development and low cost designs with minimal external components and provide a complete Bluetooth low energy qualified solution that takes less time to make a connection and consumes approximately 20 times less power than Bluetooth basic rate. Bluetooth low energy devices based on CSR101x are able to transfer simple data sets between compact devices thereby opening up a whole new class of Bluetooth applications for the Internet of Things (IoT).
