'''Am286''' was a [[second-source]]d {{intel|80286|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 ({{amd|Am386|later chips}} had to be reverse engineered instead).

== History ==
In the early 1980s [[IBM]] renewed interest in [[x86]] with the {{ibm|pc|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 [[1982 Intel-AMD technology exchange agreement|technology exchange agreement]] which focused on the x86 family of processors.

In [[1982]] Intel released the {{intel|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|intel/microarchitectures/80286|l1=80286 Microarchitecture}}
The Am286 was designed by Intel and is identical with every respect to its Intel {{intel|80286}} counterparts. AMD fabricated their chips on a [[1.5 µm process]].

=== Low-power embedded models ===
In the late 1980s AMD introduced a number of processors that had lower power dissipation than previous models specifically for embedded applications. Later AMD introduced a CMOS version with even lower power ratings.

=== Low-power CMOS models ===
{{see also|amd/am286zx-lx|l1=AMD Am286ZX/LX}}
In the early 1990s AMD once again introduced their final series of 286 processors in a totally redesigned static CMOS version which had the lowest power ratings of all their 286 models. These CMOS cores were also used in the {{amd|Am286ZX/LX}} SoC introduced around the same time.
