Power Consumption Specifications
All application power consumption data is lab data measured on an M52277EVB running the Freescale Linux BSP.
Figure 5. Power Consumption in Various Applications
All current consumption data is lab data measured on a single device using an evaluation board. Table 4 shows the typical power
consumption in low-power modes. These current measurements are taken after executing a STOP instruction.
Table 3. MCF52277 Application Power Consumption1
1 All voltage rails at nominal values: IV
DD = 1.5 V, EVDD = 3.3 V, and SDVDD = 1.8 V.
