A 33MHz version of the 68020, a 16MHz 68000 and 16MHz CMOS 68HC000 were added to the line-up of microprocessors from Motorola Inc’s Microprocessor Products Group on Monday. The company claims that the 33MHz 68020 is the fastest clock speed 32-bit microprocessor on the market, although several companies, not least Intergraph with the Clipper, are likely to dispute that claim. Motorola also quotes Dataquest figures that suggest that 746,000 68020s were sold in 1987, making it the top-selling 32 bit part. The 16MHz 68000 should appeal to low-end users such as Apple with the smaller Macintoshes, Commodore International and Atari Corp, while the 68HC000 is likely to find its way into 68000 family lap-tops and in embedded applications requiring a totally enclosed environment. The announcement does not include the top-end 68030, but Motorola promises to come out with 68030s with faster clocks than the present 25MHz limit. The 33MHz 68020 is available on 60 days delivery at $571 for quantities of 100 to 499. The 16MHz 68HC000 is out now at $34.45 for quantities of 100 to 499. The 16MHz 68000 is on 60 days delivery at $18.90 for 100-up. The 25MHz 68030 is $485 for 100-up – $86 less than the 33MHz 68020.
