The PIC 16F877A microcontroller features two Vdd pins to improve power distribution and stability. By having multiple Vdd connections, the design minimizes voltage drops and ensures that power is evenly supplied to different sections of the chip, which is crucial for maintaining performance and reliability. This configuration also allows for easier routing on the PCB, as designers can connect power from different locations, reducing the risk of noise and interference.
