33-4 Freescale Semiconductor
33.4 Power Consumption Specifications
Figure 33-1 shows typical WAIT/DOZE and RUN mode power consumption for both master and single
chip mode as measured on an M5282EVB.
For master mode the RUN mode current was measured executing a continuous loop that performs no
operation while running from the on-chip SRAM.
For WAIT/DOZE mode measurements the peripherals on the device are in their default power savings
mode, so the WAIT and DOZE power consumption are the same. Some modules can be programmed to
shutdown in WAIT and/or DOZE modes. Refer to module chapters for more information.
All single chip mode measurements were taken with all pins in general purpose input mode except for the
UART0 and FEC pins that are enabled for their module functionality; however, neither module is being
accessed at the time of the current measurement. Single chip RUN mode current was measured executing
a continuous loop that performs no operation while running from the on-chip Flash.
