Current Consumption
Table 21, Table 22, and Figure 5 show the typical current consumption in low-power modes.
Table 21. Current Consumption in Low-Power Mode, Code From Flash Memory1,2,3
1
All values are measured with a 3.30V power supply. Tests performed at room temperature.
2
Refer to the Power Management chapter in the MCF52223 Reference Manual for more information on
low-power modes.
3
CLKOUT, PST/DDATA signals, and all peripheral clocks except UART0 and CFM off before entering
low-power mode. CLKOUT is disabled.

Results are identical to STOP 00 for typical values because they only differ by CLKOUT power
consumption. CLKOUT is already disabled in this instance prior to entering low-power mode.

CLKOUT, PST/DDATA signals, and all peripheral clocks except UART0 off before entering low-power
mode. CLKOUT is disabled. Code executed from SRAM with flash memory shut off by writing 0x0 to the
FLASHBAR register.
