Thermal Characteristics
Table 8 lists thermal resistance values.
Table 7. Current Consumption in Low-Power Mode, Code From SRAM1,2,3
1
All values are measured with a 3.3 V power supply. Tests performed at room temperature.
2
Refer to the Power Management chapter in the MCF52259 Reference Manual for more information on low-power
modes.
3
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.

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.
