  • BlueNRG-2是一颗具有超低功耗蓝牙BLE的SoC单芯片,符合Bluetooth标准规范。

    BlueNRG-2扩展了ST已有的屡获殊荣的BlueNRG系列蓝牙网络处理器的功能,内置有Cortex M0内核,可运行客户应用代码。
    同时内部还包含了256KB的程序ROM、 带有保持功能的24K RAM (分为2块,各12KB), 以及SPI, UART, I2C等标准外设通讯接口。另外,BlueNRG-2还配备了多功能定时器,看门狗,实时时钟和DMA控制器等诸多模块。
    内部的ADC模块可与外部模拟传感器进行连接,也可读取内部电池电压传感器测量值。一个内置的数字滤波器可以用来处理外部的PDM数据流。
    BlueNRG-2具有同样出色的射频性能,内置的高效DC-DC转换器具有相同的超低功耗的特性,同时改善了睡眠模式下的功耗,能够进一步延长实际应用中电池的使用寿命。

    主要特性

    • 符合Bluetooth 5.0规范的低功耗蓝牙单模片上系统:
      • 主设备、从设备及多重角色
      • LE数据包长度扩展
    • 工作电压:1.7 至 3.6 V
    • 集成线性稳压器和DC-DC降压转换器
    • 工作温度范围:-40 °C至105 °C
    • 基于高性能、超低功耗Cortex-M0 32位架构内核
    • 可编程的256 kB闪存
    • 具有保持功能的24 kB RAM(两个12 kB存储区)
    • 1 x UART接口
    • 1 x SPI接口
    • 2 x I²C接口
    • 14、15或26个GPIO
    • 2 x 多功能定时器
    • 10位ADC
    • 看门狗和实时时钟
    • DMA控制器
    • PDM流处理器
    • 16 或 32 MHz 晶振

    • 可达到最高+8 dBm输出功率(在天线连接器处)
    • 卓越的射频链路设计余量(高达96 dB)
    • 精确的RSSI,有助于控制功耗
    • 8.3 mA TX 电流 (@ -2 dBm, 3.0 V)
    • 使用有源BLE栈,电流消耗低至1μA(睡眠模式)
    • 可提供ST配套集成平衡-不平衡变换器/滤波器芯片
    • 使用纽扣电池(CR2032, 230mAh) 供电, 广告间隔1000ms,平均电流损耗为15.34uA,时长:1年8个月19天。
    • 使用纽扣电池(CR2032, 230mAh) 供电, 连接状态下时间间隔为1000ms,平均电流损耗为7.059uA,时长:3年10个月12天。
    • 适用于构建符合以下射频规定的应用:ETSI EN 300 328、EN 300 440、FCC CFR47第15部分、ARIB STD-T66
    • 预置bootloader,可通过UART进行软件升级。
    • QFN32、QFN48和WCSP34封装选项
