cc2538 和 cc2562 发送和接收的电流差异那么大，是为什么？效果一样吗

Other Parts Discussed in Thread: CC2538, CC2530, CC2652R

CC2538的datasheet ，发送接收都要20几个ma

cc2562的datasheet，发送接收都小于10ma

这是为什么？

1 目前公司使用CC2530，如果我要开发新的低功耗产品，是不是使用cc2562比较好？

2 如果我要升级协调器，是选cc2538好？还是cc2562？

    推荐选择CC2652R.
    CC2538:
    – Active-Mode RX (CPU Idle): 20 mA
    – Active-Mode TX at 0 dBm (CPU Idle): 24 mA
    – Power Mode 1 (4-µs Wake-Up, 32-KB RAM
    Retention, Full Register Retention): 0.6 mA
    – Power Mode 2 (Sleep Timer Running, 16-KB
    RAM Retention, Configuration Register
    Retention): 1.3 µA
    – Power Mode 3 (External Interrupts, 16-KB RAM
    Retention, Configuration Register Retention):
    0.4 µA
    – Wide Supply-Voltage Range (2 V to 3.6 V)
    CC2652R:

    Low Power
    Wide supply voltage range: 1.8 V to 3.8 V
    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)
