Product overview

Description

The BlueNRG-LP is an ultra-low power programmable Bluetooth® Low Energy wireless SoC solution. It embeds STMicroelectronics’s state-of-art 2.4 GHz RF radio IPs combining unparalleled performance with extremely long-battery lifetime. It is compliant with Bluetooth® Low Energy SIG core specification version 5.2 addressing point-to-point connectivity and Bluetooth Mesh networking and allows large-scale device networks to be established in a reliable way. The BlueNRG-LP is also suitable for 2.4 GHz proprietary radio wireless communication to address ultra-low latency applications.

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

The main Bluetooth Low Energy 5.2 specification supported features are:

2 Mbps data rate, long range (Coded PHY), advertising extensions, channel selection algorithm #2, GATT caching, hardware support for simultaneous connection, master/slave and multiple roles simultaneously, extended packet length support.

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

The BlueNRG-LP embeds high-speed and flexible memory types:

Flash memory of 256 Kbytes, RAM memory of 64 Kbytes, one-time-programmable (OTP) memory area of 1 Kbytes, 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-LP 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-LP has a low-power RTC and one advanced 16-bit timer.

The BlueNRG-LP features standard and advanced communication interfaces:

1x SPI, 2x SPI/I2S, 1x LPUART, 1x USART supporting ISO 7816 (smartcard mode), IrDA and Modbus mode, 2x I2C supporting SMBus/PMBus, 1x channel PDM.

The BlueNRG-LP 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-LP 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-LP comes in different package versions supporting up to:

32 I/Os for the QFN48 package, 20 I/Os for the QFN32 package, 30 I/Os for the WCSP49 package.
