DC Electrical Characteristics

8.3.1

Typical Current Consumption

The current consumption is a combination of internal and external parameters and factors such as

operating frequencies, device software configuration, I/O pin loading, I/O pin switching rate, program

location in memory and so on. The current consumption is measured as described in below condition

and table to inform test characterization result.



ALL GPIO pins are in push pull mode, output high.



LDO = 1.26V



The maximum values are obtained for VDD = 3.6 V and maximum ambient temperature

(TA), and the typical values for TA= 25 °C and VDD = 3.3 V unless otherwise specified.



VDD = VBAT = AVDD = VDDIO



When the peripherals are enabled HCLK is the system clock, fPCLK0, 1 = fHCLK/2.



Program run while(1){} from Flash.
