A priority for battery-operated products is to decrease power consumption to either extend the product’s lifetime or reduce the battery size and cost. In this slide, the current consumption of the C8051F91x/0x is compared to three competitor’s products. From the data shown here, none of the competitors' MCUs is better at reducing power consumption than the C8051F91x/0x. The C8051F91x/80x has significantly lower current in sleep and active mode compared to any of the other MCU devices without limitations like failing to write flash and failing to operate the ADC below 2.25 V. The higher active mode currents of some devices make the particular family a poor choice for applications where the MCU is not constantly running.
