Table 35-11. Typical Current Consumption in Wait Mode
The Active Mode configuration and measurements are defined as follows:
Note:
• Core Clock and Master Clock Stopped
• Current measurement as shown in the above figure
• All Peripheral clocks deactivated
• VDDIO = VDDIN = 3.3V
• VDDCORE = 1.8V (Internal Voltage regulator used) and 1.62V (external supply)
• T
• Recursive Fibonacci Algorithm or division operation running from Flash memory
• All Peripheral clocks are deactivated.
• Master Clock (MCK) running at various frequencies with PLL or the fast RC oscillator
• Current measurement on AMP1 (VDDCORE)
