'''Am9080''' was a [[microprocessor family|family]] of {{arch|8}} [[microprocessor]]s reverse-engineered clones of the {{intel|8080|Intel 8080}} introduced by [[AMD]] in [[1975]].

== History ==
[[AMD]] began manufacturing their version of [[Intel]]'s {{intel|8080}} in 1975 after reverse-engineering an original off-the-shelf i8080, decapping it, and taking pictures of the die using a microscope<ref>{{apa web|last=Hailey|first=Shawn|middle=|month=December|day=29|year=1997|title=Interview with Shawn and Kim Hailey|web title=Stanford University Libraries|rmonth=June|rday=12|ryear=2014|url=http://silicongenesis.stanford.edu/transcripts/hailey.htm}}</ref>. Work was undertaken by  Shawn Hailey ,Kim Hailey, and Jay Kumar.  In [[1976]] AMD entered into a cross-licensing agreement with [[Intel]] granting them authorization to become a [[second source]]. The agreement granted each other the nonexclusive right to manufacture, use, and sell any product covered by any patents of the other party. Additionally the agreement released each other from any liability for past infringements. AMD paid Intel $325K ($25K during signing and $75K/year thereafter)<ref name=legal>{{cite book|last=Lennon|first=Michael|middle=J|year=2007|title=Drafting Technology Patent License Agreements|publisher=Aspen Publishers Online|pages=4-35 to 4-38|isbn=978-0735567481}}</ref>. The agreement was later expanded in [[1982]] which grew to incorporate the [[x86]] family of microprocessors and which later grew into legal dispute that lasted until [[1996]]<ref name=legal />.

== Architecture ==
{{main|intel/mcs-80|l1=MCS-80}}
The Am9080 is a reverse-engineered clone of the Intel 8080 and is thus architecturally identical. It's interesting to note that AMD's chip, a result of reverse engineering, produced a significantly smaller die than Intel's own {{intel|8080}}.

* Die Size 14.5 mm² (0.132" x 0.17")
* Pin 11 is connected to the substrate
