Cutting edge Bluetooth connectivity

Product description

The BlueNRG-2N is an ultra low power (ULP) network co-processor solution for Bluetooth® low energy applications. It embeds the STMicroelectronics’s state-of-the-art RF radio IPs combining unparalleled performance with extremely long battery lifetime.

It is fully compliant with Bluetooth core specification version 5.2 and supports enhanced features such as state-of-the-art security, privacy, and extended packet length for faster data transfer up to 700 kbps at application level. The BlueNRG-2N is Bluetooth® 5.2 certified ensuring interoperability with the latest generation of smartphones and other host devices.

The Bluetooth low energy stack runs on the embedded ARM Cortex-M0 core. The STMicroelectronics BLE stack is stored into the on-chip non-volatile Flash memory and it can be easily upgraded via SPI/UART as well through the dedicated STMicroelectronics software tools.

Product description

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 Public Key Acceleration (PKA) supports the modular arithmetic including exponentiation with maximum modulo size of 3136 bits and the elliptic curves over prime field scalar multiplication, ECDSA signature, ECDSA verification with maximum modulo size of 521 bits CRC calculation unit.

The BlueNRG-LPS can be configured to support standalone or network processor applications. In the first configuration, the BlueNRG-LPS operates as a single device in the application for managing both the application code and the Bluetooth Low Energy stack.
