STMicroelectronics BlueNRG-LPS Programmable BLUETOOTH® Wireless SoCs

STMicroelectronics BlueNRG-LPS Programmable BLUETOOTH® Wireless System-on-Chips (SoCs) are ultra-low-power BLUETOOTH Low Energy wireless SoC solutions. These devices embed STMicroelectronics’s state-of-the-art 2.4GHz radio IPs (optimized for ultra-low-power consumption and excellent radio performance) for unparalleled battery lifetime. BlueNRG-LPS SoCs comply with BLUETOOTH Low Energy SIG core specification version 5.3, addressing point-to-point connectivity and BLUETOOTH Mesh networking, allowing reliable large-scale device networks to be established. The BlueNRG-LPS is also suitable for 2.4GHz proprietary radio wireless communication for ultra-low latency applications.

The BlueNRG-LPS embeds an Arm® Cortex®-M0+ microcontroller that operates up to 64MHz and the BlueNRG core co-processor (DMA-based) for BLUETOOTH Low Energy timing critical operations. Enhanced security hardware support is provided by dedicated hardware functions. These devices support standalone (operating as a single device in the application for managing the application code and the BLUETOOTH Low Energy stack) or network processor applications.

Operating within a -40°C to +105°C temperature range, the STMicroelectronics BlueNRG-LPS SoCs feature a 1.7V to 3.6V power supply range. BlueNRG-LPS embeds high-speed/flexible memory types, a 12-bit ADC, battery monitoring, and a temperature sensor. The devices offer a low-power RTC and three general-purpose 16-bit timers. BlueNRG-LPS Programmable BLUETOOTH Wireless SoCs are available in a QFN-32 or a WLCSP-36 package with support for up to twenty I/Os.
