The '''MOS 6502''' is an 8-bit processor that was originally developed by a team led by the engineer Chuck Peddle. It was introduced in 1975 and it is still being produced. It was produced by the following companies.
It was second-sourced by other companies such as California Micro Devices (GTE Microcircuits), Rockwell, and Synertek. There are several less popular variants, including the 28-pin 6503, [[Rockwell R6504|6504]], 6505, 6506, and 6507 with fewer address pins (4K or 8K address space) and various control signal options.
*  California Micro Devices (GTE Microcircuits)
*  Commodore Semiconductor Group (MOS Technology)
*  Rockwell
*  Synertek
* Western Design Center
Currently it is only produced by Western Design Center (WDC)


It was a popular choice of processor because of its low price and high capabilities. It was used in multiple early computers such as the Commodore 64, Commodore VIC-20, Apple II, BBC micro, and many others.  
Western Design Center (WDC) first developed a CMOS version, which is still in production as of 2019.  In addition, several implementations (commercial as well as free) are available to synthesize the core into FPGA designs.
 
The 6502 was a popular choice of processor because of its low price and high capabilities. It was used in multiple early computers such as the Commodore 64, Commodore VIC-20, Apple II, BBC micro, and many others.
