ST BlueNRG－1蓝牙低功耗系统级芯片(SoC)评估方案

ST公司的BlueNRG-1是非常低功耗的蓝牙低功耗(BLE)单模式系统级芯片(SoC),包括有160KB可编程闪存,24KB静态RAM存储器,以及SPI,UART,I2C标准通信接口,多功能定时器,看门狗,RTC和DMA控制器等.工作电压1.7-3.6 V,主要用在汽车产出率,手表,健康和健身设备,消费类医疗产出,遥控,家庭和工业自动化,手机外设,照明和PC外设等.本文介绍了BlueNRG-1主要特性,架构框图,RF软件框图,评估平台STEVAL-IDB007V1主要特性,电路图和材料清单.
The BlueNRG-1 is a very low power Bluetooth low energy (BLE) single-mode system-on-chip, compliant with Bluetooth specification.
The BlueNRG-1 extends the features of award-winning BlueNRG network processor, enabling the usage of the embedded Cortex M0 for running the user application code.
The BlueNRG-1 includes 160 KB of programming Flash memory, 24 KB of static RAM memory with retention (two 12 KB banks) and SPI, UART, I2C standard communication interface peripherals. It also features multifunction timers, watchdog, RTC and DMA controller.
An ADC is available for interfacing with analog sensors, and for reading the measurement of the integrated battery monitor. A digital filter is available for processing 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.
