  • Are 6502 processors still made?

    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 6502 processor specification?

    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.

  • Which is faster Z80 or 6502?

    Since most memories perform write operation slowly than the read one, we can say that if we have a specific RAM we can use it with Z80 that runs four times faster than 6502. And since it was the RAM speed that was the bottleneck of computer building at times of Z80 and 6502, a computer with Z80 was faster.
  • The latest version of the 6502 is still manufactured and sold. You need to search for it by the official manufacturer's product code "W65C02S6TPG-14". Western Design Center (that first "W") licenses the manufacture of the chip to various silicon foundries, which wholesale them to dealers you can buy from online.
