The MOS Technology 6502 (typically pronounced "sixty-five-oh-two" or "six-five-oh-two") [3] is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. The design team had formerly worked at Motorola on the Motorola 6800 project; the 6502 is essentially a simplified, less expensive and faster version of ...
It is a member of the MOS Technology 6502 family, developed from the CMOS WDC 65C02 released by the Western Design Center in 1983. Like the 65C02, the 65CE02 was built on a 2 µm CMOS process instead of the original 6502's 8 µm NMOS technology, making the chip smaller (and thus less expensive) as well as using much less power.
The 65xx family of microprocessors, consisting of the MOS Technology 6502 and its derivatives, the WDC 65C02, WDC 65C802 and WDC 65C816, and CSG 65CE02, all handle interrupts in a similar fashion. There are three hardware interrupt signals common to all 65xx processors and one software interrupt, the BRK instruction.

This contrasts with most designs of the era, like the MOS 6502 and Intel 8080, which used a 16-bit address bus. The 1802 has a single bit , programmable and testable output port (Q), and four input pins that are directly tested by branch instructions (EF1-EF4).
