The DA14683 from Dialog Semiconductor is a Bluetooth v5.0 SoC that is designed for wearable devices, smart home, and industrial applications. It is based on an ARM Cortex-M0 CPU and has a 2.4 GHz CMOS transceiver with an integrated balun. The SoC features a flexible memory architecture, a cryptography engine, digital and analog peripherals and a Bluetooth Low Energy MAC engine. It delivers a Tx power of 0 dBm and has an Rx sensitivity of -94 dBm. This chip requires a DC supply of 3 V, and consumes 3.4 mA of current in Tx mode and 3.1 mA of current in Rx mode. It can be controlled via GPIO, SPI, UART, I2C, PCM, IR and USB 1.1 interfaces.
The DA14683 consists of an advanced power management unit with an integrated Buck DC-DC converter (1.7-4.75 V) that enables it to run from primary and secondary batteries as well as provide power to external devices. It has an on-chip charger and state-of-charge fuel gauge that allows it to natively charge rechargeable batteries over USB. This SoC supports Bluetooth mesh and has enhanced security features like key manipulation, secure booting, a complete public/private hardware acceleration engine and a hardware true random number generator (TRNG).
This SoC is available in an AQFN package that measures 6 x 6 mm or a WLCSP package that measures 3.406 x 3.010 mm with an antenna interface. It is ideal for wearables, Apple Homekit devices, Bluetooth mesh, human interface devices, industrial, virtual reality remotes, smart home, banking, and cloud connected applications.
