BlueNRG-M2

The BlueNRG-M2 is a low-power, highly integrated System-on-Chip (SoC) designed by STMicroelectronics for Bluetooth Low Energy (BLE) applications. It features an ARM Cortex-M0 32-bit RISC processor running at up to 48 MHz, providing efficient processing capabilities while maintaining ultra-low power consumption. The SoC includes 512 KB of Flash memory and 96 KB of SRAM, enabling robust storage and real-time data handling for complex BLE protocols and application logic. Integrated into the BlueNRG-M2 is a fully compliant BLE 5.0 radio transceiver that supports multiple PHY modes including LE 1M, LE 2M, and LE Coded, ensuring extended range and higher data rates. It also offers advanced features such as adaptive frequency hopping, enhanced security with AES-128 hardware encryption, and support for secure boot and firmware update mechanisms. These features make it ideal for applications requiring reliable wireless communication and strong data protection. The device is equipped with a rich set of peripherals, including analog-to-digital converters (ADC), timers, UART, SPI, I2C, and GPIOs, allowing flexible interfacing with various sensors, actuators, and external components. Its low-power design enables operation in multiple sleep modes, with wake-up from external events or timers, making it suitable for battery-powered devices that must maintain long operational lifetimes. Designed for IoT and wearable applications, the BlueNRG-M2 excels in smart home devices, medical sensors, industrial monitoring systems, and asset tracking solutions. Its compact form factor and minimal external component requirements reduce board space and overall system cost. Additionally, STMicroelectronics provides comprehensive development tools, including the STM32CubeMX configuration tool, a full-featured SDK, and reference designs, accelerating time-to-market for developers. The BlueNRG-M2 operates across a wide voltage range (1.71 V to 3.6 V), supporting both single-cell Li-ion batteries and coin-cell power sources. It also includes built-in brown-out detection and programmable voltage regulators to enhance system stability under varying supply conditions. With its combination of performance, power efficiency, and rich peripheral set, the BlueNRG-M2 delivers a scalable solution for next-generation BLE-enabled products.
