now I am using S912XEG384 in our product.using a 8MHz external crystal and the system clock is 32MHz,so according to the datasheet of S912XEG384,the run supply current is 72mA@Afosc=4MHz, fbus=50MHz,so if the operatinf current is 72mA*32MHz/50MHz=46mA?
another question is to calculate the sleep current,the mcu will wake up for 8ms every 80ms,so if the sleep current is 72mA*8MHz/32MHz*8ms/80ms=1.8mA OR 72mA*32MHz/50MHz*8ms/80ms=4.6mA ,which one is right?
