Run
Tested at room temperature with CPU polling a status register. All clocks were off except the UART and CFM (when
running from flash memory).
Peak current measured with all modules active, CPU polling a status register, and default drive strength with matching
load.
Tested using Auto Power Down (APD), which powers down the ADC between conversions; ADC running at 4 MHz in
Once Parallel mode with a sample rate of 3 kHz.
Tested with the PLL MFD set to 7 (max value). Setting the MFD to a lower value results in lower current consumption.
All values are measured with a 3.30V power supply. Tests performed at room temperature.
Refer to the Power Management chapter in the MCF52259 Reference Manual for more information on low-power
modes.
CLKOUT, PST/DDATA signals, and all peripheral clocks except UART0 and CFM off before entering low-power
mode. CLKOUT is disabled.
See the description of the Low-Power Control Register (LPCR) in the MCF52259 Reference Manual for more
information on stop modes 0–3.
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.
