Template:mpu VL86C020 is a 32-bit ARM microprocessor designed by Acorn and introduce by VTI in 1989. This processor is based on the ARM2 microarchitecture and was Acorn's second commercial ARM processor. This chip was manufactured on VLSI's 1.5 µm process and operated at 20 MHz.

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

Second source

This microprocessor was second-sourced by Sanyo.
