8-Bit Microprocessor Core

Overview

The W65C02S IP is a 8-bit 65xx Microprocessor available in GDSII Hardcore, RTL Softcore, and FPGA Specific Firm Cores. This is a CMOS update of the original 6502 microprocessor. This was the first licensed microprocessor IP and has been used in a wide range of applications from radiation resistant hi-rel applications such as medical implantable life-support devices to ultra high volume consumer devices.

The 8-bit data bus based architecture provides a flexible interface to memories, peripherals and other IP blocks.

WDC's RTL Softcore version provides a cycle accurate option providing for implementation onto any foundry process.

Development tools are available for creation of 65xx application code.
