The '''MB86900''' is a [[microprocessor]] produced by [[Fujitsu]],<ref>{{cite web |title=Fujitsu to take ARM into the realm of Super |url=http://www.cpushack.com/2016/06/21/fujitsu-to-take-arm-into-the-realm-of-super/ |website=The CPU Shack Museum |date=June 21, 2016 |accessdate=30 June 2019}}</ref> which implements the [[SPARC|SPARC V7]] [[instruction set architecture]] developed by [[Sun Microsystems]]. It was the first implementation of SPARC, introduced in 1986, and was used in the first SPARC-based [[workstation]], the Sun Microsystems [[Sun-4]], from 1987.<ref>{{cite web |title=Fujitsu SPARC |url=http://www.cpu-collection.de/?tn=0&l0=cl&l1=SPARC&l2=Fujitsu |website=cpu-collection.de |accessdate=30 June 2019}}</ref><ref name="timeline">{{cite web |title=Timeline |url=https://sparc.org/timeline/ |website=[[SPARC International]] |accessdate=30 June 2019}}</ref> Its chipset operated at 16.67&nbsp;MHz. The chipset consisted of two chips, the MB86900 microprocessor and the MB86910 floating-point unit. The chip set was implemented with two 20,000-gate, 1.2&nbsp;μm [[complementary metal&ndash;oxide&ndash;semiconductor]] (CMOS) [[gate-array]]s fabricated by [[Fujitsu Limited]].
