Clocks and Power Control
8.8.2
The MPC561/MPC563 provides a wide range of possibilities for power supply connections.
illustrates the different power supply sources for each of the basic units on the chip.
8.8.2.1
This supplies the final output stage of the 2.6-V pad output drivers.
8.8.2.2
This supplies all pad logic and pre-driver circuitry, except for the final output stage of the 2.6-V pad output
drivers.
8.8.2.3
VDD powers the internal logic of the MPC561/MPC563, nominally 2.6V.
8.8.2.4
The charge pump and the VCO of the SPLL are fed by a separate 2.6-V power supply (VDDSYN) in order
to improve noise immunity and achieve a high stability in its output frequency. VSSSYN provides an
isolated ground reference for the PLL.
8.8.2.5
The oscillator, time base counter, decrementer, periodic interrupt timer and the real-time clock are fed by
the KAPWR rail. This allows the external power supply unit to disconnect all other sub-units of the MCU
in low-power deep-sleep mode. The TEXP pin (fed by the same rail) can be used by the external power
supply unit to switch between sources. The IRQ[6:7]/MODCK[2:3], IRQ5/MODCK1, XTAL, EXTAL,
EXTCLK, PORESET
Circuits, including pull-up resisters, driving these inputs should be powered by KAPWR.
8.8.2.6
VDDA supplies power to the analog subsystems of the QADC64E_A and QADC64E_B modules; it is
nominally 5.0 V. VSSA is the ground reference for the analog subsystems.
8.8.2.7
VFLASH supplies the UC3F normal operating voltage. It is nominally 5.0 V. The MPC561 has no
VFLASH signal.
8.8.2.8
VDDF provides internal core voltage to the UC3F Flash module; it should be a nominal 2.6V. VSSF
provides an isolated ground for the UC3F Flash module. The MPC561 has no VDDF or VSSF signal.
