STMicroelectronics BlueNRG Bluetooth® Processador de Rede Sem Fio de Baixa Energia

O Processador STMicroelectronics BlueNRG Bluetooth® de Rede, Baixa Energia, Sem Fio é projetado para permitir tempos de execução maiores e menores, baterias mais leves em um alcance amplo de acessórios “appcessories&rdquo sem fio; tais como: punhos, óculos ou trajes interativos. Compatível com o último padrão Bluetooth 4.0, este processador de modo único Bluetooth low energy (BLE) de potência muito baixa apresenta seu próprio firmware de rádio, processador e Bluetooth para simplificar o design do wireless. A totalidade do empilhamento de baixa energia Bluetooth opera no núcleo Cortex M0. A memória Flash não volátil permite atualização de pilha em campo. Com um pico de corrente de apenas 8,2mA em modo de transmissão de 0dBm e 7,3mA em modo receptor, a BlueNRG oferece gestão de potência frugal e transmissões rápidas entre modos operacionais, deste modo minimizando potência improdutiva graças ao consumo de corrente considerado o melhor de sua categoria. O design do BlueNRG permite que os aplicativos cumpram as exigências de pico de corrente impostas pelo uso de baterias de célula em forma de moeda. Potência ultra baixa modos de espera e tempo de transição muito curto entre modos operacionais, permite consumo de corrente média muito baixa resultando em uma vida de bateria mais longa.

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.
