Architecture of the VL86C020 RISC

The VL86C020 microprocessor is a CMOS-technology reduced-instruction-set computing (RISC) device containing its own data cache on silicon. It was designed using the VLSI technology 1.5- mu m two-layer metal single-polysilicon-process rules. The part operates with a baseline performance of 16 MHz and two packages: 149-pin plastic quad flatpack. Since the CPU unit of the VL86C020 is the same as the widely available VL86C010 RISC, the standard VL86C010 processor can be made available in the 1.5- mu m process at 16 to 20 MHz as well.<
