MB86900

The MB86900 is a microprocessor produced by Fujitsu,^[1] which implements the 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.^[2][3] Its chipset operated at 16.67 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 μm complementary metal–oxide–semiconductor (CMOS) gate-arrays fabricated by Fujitsu Limited.
