The XC864 microcontroller requires two different levels of power supply:
• 5.0 V for the Embedded Voltage Regulator (EVR) and Ports
• 2.5 V for the core, memory, on-chip oscillator, and peripherals

provided from the external power supply pin. The 2.5 V power supply for the logic is
generated by the EVR. The EVR helps to reduce the power consumption of the whole
chip and the complexity of the application board design.
The EVR consists of a main voltage regulator and a low power voltage regulator. In
active mode, both voltage regulators are enabled. In power-down mode, the main
voltage regulator is switched off, while the low power voltage regulator continues to
function and provide power supply to the system with low power consumption.
