STMicroelectronics Processore di rete wireless a bassa energia Bluetooth® BlueNRG

Il processore di rete wireless a bassa energia Bluetooth® BlueNRGSTMicroelectronics è stato progettato in modo da garnatire tempi di funzionamento più estesi e batterie più piccole e leggere in una vasta gamma di “appcessori” wireless come bracciali fitness, occhiali smart o indumenti interattivi. Compatibile con il più recente standard Bluetooth 4.0, questo processore di rete a modalità singola Bluetooth Low Energy (BLE) contiene una radio, un processore e un firmware Bluetooth interni per semplificare il design wireless. L'intera pila Bluetooth Low Energy utilizza il core integrato Cortex M0. La memoria Flash non volatile consente l'upgrade all'impilamento su campo. Con una corrente di picco di soli 8,2 mA in modalità di trasmissione a 0 dBm e 7,3 mA in modalità di ricezione, BlueNRG offre una gestione energetica economica e consente una rapida transizione tra modalità operative, riducendo conseguentemente al minimo gli episodi di mancata produttività dell'alimentazione grazie a un consumo energetico ottimale. Il design BlueNRG permette alle applicazioni di soddisfare i rigorosi requisiti di corrente di picco consigliati e imposti dall'uso di batterie a celle a bottone standard. Le modalità di sospensione a bassissima potenza e i tempi di transizione estremamente ridotti tra le modalità operative garantiscono un consumo di corrente medio estremamente ridotto, che offre una durata più estesa della batteria.

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.
