Charles Ingerham Peddle was an American electrical engineer best known as the main designer of the MOS Technology 6502 microprocessor, the KIM-1 single-board computer, and its successor, the Commodore PET personal computer, both based on the 6502.

The MOS Technology 6502 is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. The design team had formerly worked at Motorola on the Motorola 6800 project; the 6502 is essentially a simplified, less expensive and faster version of that design.
