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.
