KAPWR and VSS power the following clock unit modules: oscillator, PITRTCLK and TMBCLK
generation logic, timebase, decrementer, RTC, PIT, system clock control register (SCCR), low-power and
reset-control register (PLPRCR), and reset status register (RSR). All other circuits are powered by the
normal supply pins: VDD, QVDDL, NVDDL, VDDF, VDDSYN, VFLASH, VDDH and VSS. The power
supply for each block is listed in
The following are the relations between different power supplies:

VDD = QVDDL = NVDDL = VDDSYN = VDDF = 2.6 V ± 0.1 V
KAPWR = VDD ± 0.2 V (during normal operation)
VDDH = VDDA = VFLASH = 5.0 ± 5%
KAPWR = 2.6 ± 0.1 V (during standby operation)
IRAMSTBY = current source > 50 µA, < 1.75 mA (average)
Basic Power Structure
General Power Supply Definitions
The power supply inputs VDD, QVDDL, NVDDL, VDDSYN, and VDDF
should all be connected to the same 2.6-V power supply. The KAPWR
power supply can be connected to a 2.6-V standby power supply. If
KAPWR is not connected to a standby power supply, it should be connected
to the same power supply as VDD. IRAMSTBY is the input to an
approximately 1.7 volt regulator. It must be connected through a resistor to
a standby power supply. The power supply inputs VDDH and VFLASH
should be connected to the same 5.0-V supply. VDDA can be isolated from
VDDH, but should be the same approximate voltage.
