Chapter 2 External Signal Description

V
I/O buffer circuitry, the ADC module, and to an internal voltage regulator. The internal voltage regulator
provides regulated lower-voltage source to the CPU and other internal circuitry of the MCU.
Typically, application systems have two separate capacitors across the power pins: a bulk electrolytic
capacitor, such as a 10μF tantalum capacitor, to provide bulk charge storage for the overall system, and a
bypass capacitor, such as a 0.1μF ceramic capacitor, located as near to the MCU power pins as practical
to suppress high-frequency noise.
