STMicroelectronics BlueNRG Bluetooth® Drahtloser Netzwerkprozessor mit niedrigem Energieverbrauch

STMicroelectronics BlueNRG Bluetooth® drahtloser Netzwerk-Prozessor mit niedrigem Energieverbrauch ist dazu entworfen, längere Betriebszeiten zu ermöglichen und kleinere, leichtere Batterien in vielem Drahtlos-Zubehör, wie Fitness-Armbändern, Smart-Brillen oder interaktiver Kleidung zu ermöglichen. Kompatibel mit dem modernsten Bluetooth 4.0 Standard, verfügt dieser Einzelmodus-Niedrigspannungs-Bluetooth Netzwerk-Prozessor mit sehr geringem Stromverbrauch über ein eigenes Radio, Prozessor und Bluetooth Firmware, um das drahtlose Design zu vereinfachen. Der gesamte Bluetooth Niedrigspannungs-Stapel läuft auf dem integrierten Cortex M0 Kern. Der nicht flüchtige Flash-Speicher erlaubt ein Upgrade des Stapels vor Ort. Mit einem Spitzenstrom von nur 8,2 mA im Übertragungsmodus bei 0 dBm und 7,3 mA im Empfangsmodus, bietet BlueNRG sparsames Leistungsmanagement und schnelle Übergänge zwischen den Betriebsmodi und minimiert hierbei unproduktiven Leistungsverbrauch aufgrund seines optimalen Stromverbrauchs. Das Design von BlueNRG ermöglicht Anwendungen, die durch Knopfzellenbatterien auferlegte Anforderungen im Hinblick auf den knappen Spitzenstrom erfüllen. Schlafmodi mit besonders geringem Stromverbrauch und sehr kurzen Übertragungszeiten erlauben einen sehr niedrigen, durchschnittlichen Stromverbrauch, was zu einer längeren Batterielaufzeit führt.

BlueNRG-MS

Bluetooth Low-Energy Network Processor Supporting Bluetooth 4.1 Core Specification

The BlueNRG-MS is a very low-power Bluetooth Low-Energy (BLE) single-mode network processor, compliant with Bluetooth specification v4.1. The BlueNRG-MS supports multiple roles simultaneously and can act at the same time as Bluetooth Smart sensor and hub device.

The Bluetooth Low-Energy stack runs on the embedded Arm® Cortex® M0 core. The stack is stored on the on-chip non-volatile Flash memory and can be easily upgraded via SPI. The device comes pre-programmed with a production-ready stack image (whose version could change at any time without notice). A different or more up-to-date stack image can be downloaded from the ST web site and programmed on the device through the ST provided software tools.

The BlueNRG-MS allows applications to meet the tight advisable peak current requirements imposed with the use of standard coin cell batteries. The maximum peak current is only 10mA at 1dBm of output power. Ultra low-power sleep modes and very short transition times between operating modes allow very low average current consumption, resulting in longer battery life. The BlueNRG-MS offers the option of interfacing with external microcontrollers using the SPI transport layer.

BlueNRG-1

Bluetooth Low-Energy System-On-Chip

The BlueNRG-1 is a very low-power BLE single-mode system-on-chip (SOC), compliant with Bluetooth specifications. The BlueNRG-1 extends the features of the award-winning BlueNRG network processor, enabling the usage of the embedded Cortex M0 to run the user's application code.

The BlueNRG-1 includes 160kB of programming Flash memory, 24kB of static RAM memory with retention (two 12kB banks) and SPI, UART, I²C standard communication interface peripherals. It also features multifunction timers, watchdog, RTC, and DMA controller.

An ADC is available to interface with analog sensors and to read the measurement of the integrated battery voltage sensor. A digital filter is available to process a PDM stream.

The BlueNRG-1 offers the same excellent RF performance of the BlueNRG radio, and the integrated high-efficiency DC/DC converter keeps the same ultra-low power characteristics, but the BlueNRG-1 improves the BlueNRG sleep mode current consumption allowing a further increase in the battery lifetime of the applications.
