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.
