Thermal Characteristics
Figure 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 3.30V 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.

5
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.
