ST BlueNRG－1可编蓝牙LE 5.2无线SOC开发方案

ST公司的BlueNRG-1是可编蓝牙LE 5.2无线SOC,是非常低功耗蓝牙低能量(BLE)单模式系统级芯片(SoC),和蓝牙指标兼容.BlueNRG-1扩展了得奖的BlueNRG网络处理器的性能,使得嵌入的Cortex M0能运行用户应用代码.器件包括160kB可编闪存,24kB静态RAM存储器,带有保持(两个12kB组)和SPI,UART,I2C标准通信接口外设.它还具有多功能计时器,看门狗,RTC和DMA控制器.其ADC用来和模拟传感器接口,和读取集成电池电压传感器的测量值.数字滤波器用来处理PDM流.BlueNRG-1提供BlueNRG无线电的同样优秀的RF性能,而集成的高效率DC/DC转换器保持同样的超低功耗特性,但改善了BlueNRG睡眠模式电流消耗,从而进一步增加了应用时的电池寿命.器件工作电压1.7V-3.6V,集成了线性稳压器和DC/DC降压转换器,工作温度-40 C 到 105 C.可选择QFN32和WCSP34封装.主要用在手表,健美健身和运动,消费类医疗,安全/近程传感器,遥控,家庭和工业自动化,移动电话外设,照明和PC外设.本文介绍了BlueNRG-1主要特性,架构图,时钟树图和多种应用电路,以及BlueNRG-1和BlueNRG-2开发板主要特性,以及电路图.

The BlueNRG-1 is a very low power Bluetooth low energy (BLE) single-mode system-on-chip, compliant withBluetooth specifications.

The BlueNRG-1 extends the features of award-winning BlueNRG network processor, enabling the usage of theembedded Cortex M0 to run the user application code.

The BlueNRG-1 includes 160 kB of programming Flash memory, 24 kB of static RAM memory with retention (two12 kB banks) and SPI, UART, I²C standard communication interface peripherals. It also features multifunctiontimers, watchdog, RTC and DMA controller.

An ADC is available to interface with analog sensors, and to read the measurement of the integrated batteryvoltage 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 highefficiency DC-DC converter keeps the same ultra-low power characteristics, but the BlueNRG-1 improves theBlueNRG sleep mode current consumption allowing a further increase in the battery lifetime of the applications.
