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:
2 Mbps data rate, long range (Coded PHY), advertising extensions, channel selection algorithm #2, GATT caching, Direction Finding (AoA/AoD), hardware support for simultaneous connection, master/slave and multiple roles simultaneously, extended packet length support, LE Ping procedure, periodic advertising and periodic advertising sync transfer, LE power control and path loss monitoring.
In addition, the BlueNRG-LPS provides enhanced security hardware support by dedicated hardware functions:
True random number generator (RNG), encryption AES maximum 128-bit security co-processor, public key accelerator (PKA), CRC calculation unit, 64-bit unique ID, flash memory read and write protection.
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.
The BlueNRG-LPS embeds high-speed and flexible memory types:
Flash memory of 192 Kbytes, RAM memory of 24 Kbytes, one-time-programmable (OTP) memory area of 1 Kbyte, ROM memory of 7 Kbytes (ST reserved area).
Direct data transfer between memory and peripherals and from memory-to-memory is supported by eight DMA channels with a full flexible channel mapping by the DMAMUX peripheral.
The BlueNRG-LPS embeds a 12-bit ADC, allowing measurements of up to eight external sources and up to three internal sources, including battery monitoring and a temperature sensor.
The BlueNRG-LPS has a low-power RTC and three general purpose 16-bit timers.
The BlueNRG-LPS features standard and advanced communication interfaces:
1x SPI/I2S, 1x LPUART, 1x USART supporting ISO 7816 (smartcard mode), IrDA and Modbus mode, 1x I2C supporting SMBus/PMBus.
The BlueNRG-LPS operates in the -40 to +105 °C temperature range from a 1.7 V to 3.6 V power supply. A comprehensive set of power-saving modes enables the design of low-power applications.
The BlueNRG-LPS integrates a high efficiency SMPS step-down converter and an integrated PDR circuitry with a fixed threshold that generates a device reset when the VDD drops under 1.65 V.
The BlueNRG-LPS comes in different package versions supporting up to:
20 I/Os for the QFN32 package. 20 I/Os for the WLCSP36 package.
