What is the pin voltage of PIC microcontroller?
The pin voltage of a PIC microcontroller refers to the voltage that is supplied to the pins for input , output , and sometimes power functions. This voltage is determined by the power supply provided to the microcontroller, as well as the configuration and state of the pins. Below are some key considerations related to the pin voltage of a PIC microcontroller: 1. VDD and VSS (Power Supply Pins) VDD : This is the supply voltage for the PIC microcontroller's core, typically ranging from 3.3V to 5V , depending on the specific PIC model. For 3.3V systems : Common PIC microcontrollers like the PIC32 family operate at 3.3V . For 5V systems : Older or low-power PIC microcontrollers (like the PIC16 or PIC18 series) often operate at 5V . VSS : This is the ground pin (GND), typically connected to the system ground. 2. Input Pins (GPIO) High Logic Level (Logic High) : The voltage required to register a logic high (1) on a digital input pin depends on the VDD voltage. For example: For...
