A80C286-12 - ES - I804202S - (m)(c)INTEL '87

Introduced in 1982, the original iAPX286 architecture evolved until the 90s. First clocked at 8 and 10 MHz, then 4 and 6 MHz, Intel finally released a higher frequency after the launch of their successor (the 80386). This 12 MHz part is build using the CHMOS III 1.5µm process, the same that was used for the first 80386 chips. Earlier 12 MHz 286s (marked A80286-12 without "C") were built with the older NMOS process. Power consumption dropped dramatically with this new process : from 3.15W for the A80286-12 to 1.1W for the A80C286-16! This Engineering Sample was built in January 1998 and uses the 68 pin PGA package.
