Western Design Center
The Western Design Center (WDC), maker of microprocessors, microcontrollers, and related support chips, was founded in 1978 by co-holder of the MOS Technologies 6502 patent, Bill Mensch, himself a former MOS Technologies employee. WDC is located in Mesa, Arizona.
In addition to the actual microchips, WDC offers the chips' designs as IP cores to be used inside other chips (like ASICss), and provides ASIC and embedded systems consulting services revolving around their processor designs. WDC also makes compilers and assemblers for their processors.
Notable WDC products include:
- W65C02 - bug-fixed CMOS version of the originally NMOS-based 6502
- W65C22 - MOS Technologies VIA-compatible I/O chip
- W65816 - 16-bit compatible follow-up to the 6502
