Is the 6502 still made?
It’s Still in Production The Western Design Center, Inc, founded by Bill Mensch of Motorola and MOS fame, sells modern versions of the 6502 in both the classic 40 pin DIP package (appears to be pin-compatible with the original), as well as more modern surface mount packages.
What was the 6502 used in?
Popular video game consoles and computers, such as the Atari 2600, Atari 8-bit family, Apple II, Nintendo Entertainment System, Commodore 64, Atari Lynx, BBC Micro and others, use the 6502 or variations of the basic design.
Is the 6502 a RISC processor?
Several (common) characteristics of RISC were identified, and the article ultimately concluded that the 6502 was not RISC. One characterstic was a large number of general purpose registers.
How many transistors does a 6502 have?

Who made the 6502 CPU?
The breakthrough that permitted this cost reduction, says Bill Mensch, who created the 6502 with Peddle, was a minimal instruction set combined with a fabrication process that “yielded 10 times as many good chips as the competition.” The 6502 almost single-handedly forced the price of processors to drop, helping launch …
What is a 6502 assembler?
6502 assembly is a very low-level language that works specifically for the 6502 microprocessor — a very popular processor from the 1970s.
How many transistors are in a 6502 CPU?
Is the 6502 pipelined?
The 6502 was pipelined and the Z80 as well. Pipelining used to refer to the fact that instruction were performed piecemeal in a number of stages requiring multiple clock cycles as opposed to performing the entire instruction in one very long clock cycle.
Is Z80 still used?
Z80s are still used even today, where a high-power processor isn’t needed. Many Texas Instruments graphing calculators still use Z80 processors today, as well as many other low-cost devices that need a little processing power.
How many registers are in a 6502 microprocessor?
Like its precursor, the 6800, the 6502 has very few registers. The 6502’s registers include one 8-bit accumulator register (A), two 8-bit index registers (X and Y), 7 processor status flag bits (P), an 8-bit stack pointer (S), and a 16-bit program counter (PC).
What consoles use the 6502 microcontroller?
As a result, the 6502 (or variations thereof) formed the heart of many popular video game consoles and computers, such as the Atari 2600, Atari 8-bit family, Apple II, Nintendo Entertainment System, Commodore 64, Atari Lynx, BBC Micro, and others.
What is the difference between the 6502 and 6800?
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 that design. When it was introduced in 1975, the 6502 was the least expensive microprocessor on the market by a considerable margin.
What is the 6502 documents archive?
A repository for software programs and useful subroutines written in 6502 assembly language. Learn how to interface hardware with your 6502 project through examples with schematics and source code. The Documents Archive houses documentation archived in electronic form that is available for download.
