The first product developed by WDC was the WDC 65C02, a CMOS version of the NMOS based MOS Technology 6502 microprocessor. The 65C02 reduced the power consumption, improved noise immunity and added some new instructions. The 65C02 was subsequently adopted for use in the
Apple IIc computer and, later, in an enhanced version of the
Apple IIe. Mensch's next design, which was to become an important product at WDC, was a 65C02-compatible 16-bit microprocessor, the 65C816, later designated W65C816S. The 65C816's design came about following consultation with Apple and was adopted by them for use in the
Apple IIGS computer. The 65C816 was later chosen as the core of the
Ricoh 5A22 processor that powered the
Super Nintendo Entertainment System.
