STMicroelectronics has introduced the new third-generation Bluetooth System-on-Chip (SoC) BlueNRG-LPS which uses Bluetooth-specified technology including both angle-of-arrival (AoA) and angle-of-departure (AoD), as computed from signals captured by an antenna array and enables a wide variety of applications that require indoor navigation, geofencing, and asset tracking, as well as real-time location finding for tools, assets, and goods. By determining the direction of a Bluetooth Low Energy (BLE) signal, this Bluetooth 5.3 certified SoC can precisely estimate movement and location with centimetre accuracy.


With its streamlined architecture and I/O peripherals, and program and data memories (192KB eFlash and 24KB SRAM, respectively) sized for lightweight end products, BlueNRG-LPS is ideal for cost-sensitive and high-volume applications. These include general-purpose wireless sensors, medical appliances, keyless-entry systems, remote controls, and smart remote metering. Also integrating a high-efficiency step-down converter and protection circuitry, this SoC further simplifies and reduces the required bill-of-material (BOM) and allows for a much cheaper two-layer PCB design.


This SoC features Bluetooth LE Power Control specification which enables fine-tuning of RF output power in 1dBm increments, and up to +8dBm, to permit longer battery runtime. Bluetooth Path-Loss Monitoring enhances radio-link quality and prevents interference, ensuring robust connections for improved interaction between devices, even in crowded places, and faster response times. Support for Bluetooth 5.3 long range, 2Mbps high-speed data rate, periodic advertising, simultaneous connection, and multi-role specifications also ensure superior user experiences with equipment powered by BlueNRG-LPS. Moreover, there are also dedicated hardware functions and cryptographic IPs to support enhanced security.
