There hasn’t been any indication that the CMOS-only iAPX-86 family second-source, Harris Corp is not still in Intel Corp’s good books, but Harris has come out with a part that Intel definitely didn’t want – a 20MHz CMOS version of the 80286. The 80C286 is currently being sampled by the Melbourne, Florida company, and is promised for volume deliveries in September. It costs $282 when you buy 1,000 or more. Harris also reckons that for 16-bit code, the part executes 80286 code more efiiciently than the 80386, using up to 30% fewer clock cycles to perform the same instructions. Maximum operating current is 310mA, making it an interesting choice for high-performance lap-top designers. Intel is widely thought to have put out the 80386SX 16-bit bus version of the 386 in part at least to put a crimp on sales of 80286s clocked faster than its current 12MHz part, so it is not likely to be too happy at Harris touting a 20MHz variant.
