WDC 65C02

Common card · No. 416112

The WDC 65C02 microprocessor is an enhanced CMOS version of the MOS Technology 6502, an 8-bit microprocessor originally implemented using nMOS technology. Developed by Western Design Center (WDC), the 65C02 consumes less power than the 6502, fixes several of its issues, and adds instructions and addressing modes. At the same clock speed, its power consumption is approximately 10 to 20 times lower than that of the original 6502. Its low power consumption has made it suitable for portable computers and industrial microcontroller systems. The 65C02 has also been used in home computers and embedded systems, including implanted medical devices. Development of the 65C02 began in 1981, with samples available by early 1983. The chip was officially released shortly afterward. Apple Computer, which had used the original 6502 in its Apple II family of computers, was an early adopter of the 65C02, incorporating it into the compact Apple IIc and the Enhanced Apple IIe, both introduced in 1984.
