Description

General part information

BlueNRG-LPS Series

The BlueNRG-LPS is an ultra-low power programmable Bluetooth® Low Energy wireless SoC solution. It embeds STMicroelectronics’s state-of-the-art 2.4 GHz radio IPs, optimized for ultra-low-power consumption and excellent radio performance, for unparalleled battery lifetime. It is compliant with Bluetooth Low Energy SIG core specification version 5.3 addressing point-to-point connectivity and Bluetooth Mesh networking and allows large-scale device networks to be established in a reliable way. The BlueNRG-LPS is also suitable for 2.4 GHz proprietary radio wireless communication to address ultra-low latency applications.

The BlueNRG-LPS embeds a Arm® Cortex®-M0+ microcontroller that can operate up to 64 MHz and also the BlueNRG core co-processor (DMA based) for Bluetooth Low Energy timing critical operations.

The main Bluetooth Low Energy 5.3 specification supported features are:
