Figure 2-4. Operation range of the different circuit blocks
2.4 Current consumption
The tables below give the current consumption for the circuit in different configurations. The figures are indicative
only and may change as a function of the actual software implemented in the circuit.
Table 2-5 gives the current consumption for the flash version of the circuit. The peripherals are disabled. The
parallel ports A and B are configured in input with pull up, the parallel port C is configured as an output. Their pins
are not connected externally. The pin RESET is connected to VSS and the pin VPP/TEST is connected to VBAT.
The inputs of the acquisition chain are connected to VSS.

For more information concerning the current consumption of the zoomingADC
consumption in the acquisition chain documentation which shows the current consumption of this block as a
function of temperature and voltage and for different configurations of the PGA and ADC.
The power consumption of the ROM version of the circuit is identical if it is configured as shown in Figure 2-2. In
the high speed configuration, the current consumption will increase proportional with VBAT.
