Western Design Center 65816
The W65816 (also: 65C816), a 16-bit microprocessor developed by the Western Design Center (WDC), is an expanded and compatible successor to the venerable MOS Technology 6502. The 65816 has two 16-bit index registers, a stack pointer, a 16-bit direct page register , and a 24-bit address bus.
Notable uses of the W65816
- Apple IIGS (2.8 MHz)
- Super Famicom/Super Nintendo video game consoles (3.58 MHz)
- SuperCPU accelerators for the Commodore 64 and 128 (20 MHz)
- 65C816ADP "Hyper-Speed" accelerators for the Atari XL /Atari XE (1.79/14 MHz)
- C-One (Commodore One) FPGA-based reconfigurable computer (20 MHz)
- The Mensch Computer (using the W65C265 microcontroller)
