BlueNRG-LPS

BlueNRG-LPS is a low-power System-on-Chip (SoC) from STMicroelectronics designed for Bluetooth Low Energy (BLE) 5.3 applications. It integrates an ARM Cortex-M0+ processor, a dedicated BLE radio, and extensive on-chip memory including 256 KB Flash and 32 KB SRAM, enabling efficient execution of complex wireless protocols with minimal power consumption. The device operates in a wide voltage range of 1.6 V to 3.6 V, making it suitable for battery-powered systems. Key features include ultra-low power modes such as Stop mode (current consumption as low as 1.4 μA), Deep Sleep mode (less than 0.5 μA), and Wake-up from external events, which are essential for extending battery life in portable devices. The SoC supports advanced BLE functionalities like advertising extensions, connection parameters, and secure data transfer using AES-128 encryption. It also includes a rich set of peripherals such as UART, SPI, I2C, and GPIOs, allowing flexible system integration. Designed for industrial, consumer, and healthcare applications, BlueNRG-LPS excels in smart sensing, asset tracking, wearable devices, and IoT nodes where long battery life and reliable connectivity are critical. Its compact QFN32 package and minimal external components reduce board space and cost while maintaining high performance. The chip is supported by ST’s comprehensive development ecosystem, including STM32CubeMX configuration tools, BLE stack software, and reference designs, accelerating time-to-market for developers. The SoC also offers robust hardware-based security features, including secure boot, tamper detection, and protected memory regions, ensuring data integrity and device authenticity. With integrated analog-to-digital converters (ADCs) and programmable timers, it enables precise sensor interfacing and timing control without requiring additional ICs. This makes it ideal for applications involving environmental monitoring, health sensors, or industrial automation systems that require both wireless communication and real-time data processing.
