Am286 was a second-sourced 286 chip designed by Intel and manufactured by AMD. The Am286 was introduced into market in 1984 after Intel delivered them their designs very late, likely intentionally. These were the last designs AMD ended up receiving from Intel (later chips had to be reverse engineered instead).
History
In the early 1980s IBM renewed interest in x86 with the IBM PC being on track to be released in August 1981. However, IBM requires any chip they use to have at least one second source for a number of reasons. This in turn caused Intel to renew and expand their original 1976 agreement with AMD in 1981. Additionally, in 1982 they signed the technology exchange agreement which focused on the x86 family of processors.
In 1982 Intel released the 80286. After a rather large delay AMD received the designs from Intel and finally entered production in 1984. The Am286 was identical with every respect to Intel's 286.
Architecture
- Main article: 80286 Microarchitecture
The Am286 was designed by Intel and is identical with every respect to its Intel 80486 counterparts. AMD fabricated their chips on a 1.5 µm process.
