  • What is the architecture of 6502?

    The 6502 Architecture
    The 6502 is strictly an 8-bit architecture, with a single 8-bit accumulator register, and can access a maximum of 64K bytes of random access memory. Memory addresses are exactly 16 bits in length, because 216 = 65536 = 64K. Valid addresses range from 0 up to 65535.

  • Is 6502 still used?

    As one of the most widely used microprocessor architectures of all time, the CMOS related form of the 6502 developed by the Western Design Center is still in production today, with an estimated six billion units so far produced.

  • Is the 6502 a microprocessor?

    6502 Micro-processor
    The geek was Steve Wozniak, the computer was the Apple I, and the chip was the 6502, an 8-bit microprocessor developed by MOS Technology.
  • The 6502 is an 8-bit processor with a 16-bit address bus. It is therefore able to access 64 kilobytes (216 bytes). Since each 16-bit address is comprised of two 8-bit bytes, memory can be viewed as 256 pages of 256 bytes each.
