Bluetooth® Smart/Bluetooth Low Energy

Our Bluetooth Smart (Bluetooth Low Energy) solutions include highly integrated SoCs with plentiful Flash and SRAM memory utilizing Arm® Cortex®-M cores. These products enable ultra-low-power operation without compromising radio performance. In addition to providing complete SoCs, a host Bluetooth Low Energy stack is provided, as well as several GATT profiles and services.
