TM4C 和 STM32L4 哪个功耗更低?

TM4C123 和 STM32L4 最高设计频率都是80MHz,那么在各种低电压模式下,哪家芯片功耗更低呢?或者在同样频率下,哪个功耗更低呢?

在ST的官网很容易查到STM32L4的功耗指标,但TM4C的功耗指标好像标示并不明显,目前没有找到,不知道在DataSheet中该看哪一章?

TM4C123、129系列是不是不以低功耗为主打?印象里TI的M4F系列是功耗最低,性能最好的,那个是MSP432吧?

希望能通过此贴对比一下。

以下是STM32L4的功耗指标:

Ultra-low-power with FlexPowerControl

  • 1.71 V to 3.6 V power supply
  • -40 °C to 85/105/125 °C temperature range
  • 8 nA Shutdown mode (2 wakeup pins)
  • 28 nA Standby mode (2 wakeup pins)
  • 280 nA Standby mode with RTC
  • 1.0 μA Stop 2 mode, 1.28 μA Stop 2 with RTC
  • 84 μA/MHz run mode
  • Batch acquisition mode (BAM)
  • 4 μs wakeup from Stop mode
  • Brown out reset (BOR) in all modes except shutdown
  • Interconnect matrix
