CC26X2型号选择问题

Other Parts Discussed in Thread: CC2640R2F, CC2652RB, CC2652R

工程师们，你好，昨天我提了个关于CC2640R2F的multi role问题，工程师Viki Shi说推荐升级到CC26X2的型号，我们的需求是功耗尽量最低，但是我们的数据量较大，主机端基本上是处于一个一直接收数据的状态，选择什么型号较为合适呢？(基于ble5stack，从机希望能达到理论上的一对八)

    CC2652的功耗如下，稍高于CC2640R2F:
    Active-Mode RX: 6.9 mA
    Active-Mode TX 0 dBm: 7.3 mA
    Active-Mode TX 5 dBm: 9.6 mA
    Active-Mode MCU 48 MHz (CoreMark):
    3.4 mA (71 µA/MHz)
    Sensor Controller, Low Power-Mode, 2 MHz, running infinite loop: 30.8 µA
    Sensor Controller, Active-Mode, 24 MHz, running infinite loop: 808 µA
    Standby: 0.94 µA (RTC on, 80KB RAM and CPU retention)
    Shutdown: 150 nA (wakeup on external events)

    CC2640R2F的功耗如下:
    Active-Mode RX: 5.9 mA
    Active-Mode TX at 0 dBm: 6.1 mA
    Active-Mode TX at +5 dBm: 9.1 mA
    Active-Mode MCU: 61 µA/MHz
    Active-Mode MCU: 48.5 CoreMark/mA
    Active-Mode sensor controller:
    0.4mA + 8.2 µA/MHz
    Standby: 1.1 µA (RTC running and RAM/CPU retention)
    Shutdown: 100 nA (wake up on external events)

    您推荐的型号是CC2652R吗？我在官网上看到有CC2652RB和CC2652R等型号，RB型号有源模式上面只有一个7.9mA，这个的功率是多少分贝呢？如果在5dBm的情况下是7.9mA，选择这个型号是否更好(希望能传输更远的距离)？

    这是CC2652RB的功耗参数，比CC2652R还高一点，两者的区别就是CC2652RB不要外部晶振，可以省一个晶振器件，看你需不需要了
    – Active-Mode RX: 7.3 mA
    – Active-Mode TX 0 dBm: 7.9 mA
    – Active-Mode TX 5 dBm: 10.2 mA
    – Active-Mode MCU 48 MHz (CoreMark): 3.4 mA (71 μA/MHz)
    – Sensor Controller, Low Power-Mode, 2 MHz, running infinite loop: 30.8 μA
    – Sensor Controller, Active-Mode, 24 MHz, running infinite loop: 808 μA
    – Standby: 0.94 µA (RTC on, 80KB RAM and CPU retention)
