5.3. DC Characteristics

Current Consumption (Design Target Value)

Table 5-3 shows a list of the current consumption values. Each value is an average operating value with a recommended connection

of each power supply pin. For the measured values, the measurement is done under our company’s evaluation environment.

The current consumption characteristics are based on the following conditions, unless specified otherwise.



Ambient temperature (Ta): 25°C



CPU clock frequency: 32 MHz



Sleep clock frequency: 32.768 kHz, using a crystal resonator



Power supply source in the normal operating mode: DC/DC convertor



VBAT = VDDIO = 3.0 V



VSSA = VSSRFIO = VSSDC = VSSD = VSSX = 0 V

Table 5-4 shows a list of DC characteristic values for each pin
