March 02, 2021 by Mouser Electronics

This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.


STMicroelectronics’ BlueNRG-LP is an ultra-low-power programmable Bluetooth Low Energy Wireless SoC that enables BLE connectivity for applications including home and industrial automation, smart lighting, fitness and wellness devices, security, and mobile phone peripherals. 

The BlueNRG-LP includes a 64MHz Arm Cortex-M0+ microcontroller, high-speed and flexible memories, and the BlueNRG core DMA-based coprocessor, which handles Bluetooth Low Energy timing critical operations. The device is Bluetooth 5.2 certified, supporting 2Mbps data rates, long range communication, advertising extensions, and more. The radio offers very high sensitivity and an output that’s programmable up to +8dBm. 

It also provides ultra-low power operation, with low current consumption in active and low-power modes. The BlueNRG-LP is offered in various compact packages and is available with up to 32 I/Os.
