SM470的芯片手册上standby模式的最大工作电流只有50多mA，但实际使用的时候，却有105mA左右，请问这么大的差距是怎么原因引起的呢？
105mA的话，感觉您现在没有真正在standby模式
请您尝试下面的配置代码
GCR |= FLCONFIG; // Must be in flash config mode FMMAC1 = PSLEEP_MAX; // pump sleep to standby time FMMAC2 = BANK0_ENA + PMPPWR_SLEEP + PSTDBY_MAX; // Pump power sleep bank0 FMBAC1 = BNKPWR_SLEEP+ BSTDBY_MAX + 0xff00; // Bank power sleep 256 cycles // before flash shut down FMBAC2 = PIPELINE_MODE + BSLEEP_MAX; // 1 wait states FMMAC2 = BANK1_ENA + PMPPWR_SLEEP + PSTDBY_MAX; // Pump power sleep bank1 FMBAC1 = BNKPWR_SLEEP+ BSTDBY_MAX + 0xff00; // Bank power sleep 256 cycles // before flash shut down FMBAC2 = PIPELINE_MODE + BSLEEP_MAX; // 1 wait states FMREGOPT = ENPIPE; // ENABLE PIPELINE MODE CLKCNTL = PPWNOVR + LPM_STANDBY; // standby mode dummy=CLKCNTL; // Dummy access
