Vybrid Power Consumption and Options, Rev. 0
6 Freescale Semiconductor
Power consumption in selected use cases
Estimated currents:
• For 25°C and 100% utilization it is up to 700mA.
• For 85°C and 100% utilization it is up to 850mA.
6 Power consumption in selected use cases
The following sections contain the results of measuring power supply currents in defined measuring
points, in selected use cases. All data are measured in normal run mode at room temperature (22-25°C).
6.1 Baremetal
