PSoC Functional Overview

The key feature set of the Linear Power PSoC family is the ability to be powered from and connect to voltages above the standard 5V logic voltage used by most microcontrollers. The PSoCs HVdd pin can connect to a supply voltage of up to 36V. Internally, an LDO regulator converts the supply voltage to 5V for powering the analog system, digital system, the core, and the GPIO.
