  • 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.

  • What is subtract with carry 6502?

    The 6502 has a SBC operation (subtract with carry) that subtracts two numbers and also subtracts the borrow bit. If the (unsigned) operation results in a borrow (is negative), then the borrow bit is set. However, there is no explicit borrow flag - instead the complement of the carry flag is used.

  • What is the size of 6502 instruction?

    Hence 6502 machine instructions vary in length from one to three bytes. The operand is stored in the 6502's customary little-endian format.
  • 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.
