'''VL86C020''' is a {{arch|32}} [[ARM]] microprocessor designed by [[Acorn]] and introduce by [[vti|VTI]] in [[1989]]. This processor is based on the {{acorn|ARM3|l=arch}} microarchitecture and was Acorn's second commercial ARM processor. This chip was manufactured on [[VLSI Technology|VLSI]]'s [[1.5 µm process]] and operated at 20 MHz an 25 MHz.

This processor operates performs at over three times the performance of its {{\\|VL86C010|predecessor}} thanks to its higher clock speed and on-die cache.

== Second source ==
This microprocessor was second-sourced by [[Sanyo]].
