WDC has proudly supported educational institutions and continues to do so. In 2005, WDC supported the Introduction to VLSI Design with System on Chip Design Reuse: A Tutorial for Students. This tutorial was created in the absence of a VLSI course that Bill Mensch taught at ASU East. The tutorial focused on the W65C122S, a GDSII-based microcontroller featuring the W65C02, W65C22, RAM, and ROM. The design from this tutorial was taped out once through Tanner Research, however, the steps for tapeout are not covered in the tutorial. WDC continues to support professors and students of VLSI design, by offering chips, boards, and IP for student use at and within university Colleges of Engineering.
Many universities worldwide still teach VLSI design, however, there are still many that either never had a course, dropped the course after the teaching professor left, or the course is lacking the inclusion of an option to tape out and evaluate a completed chip.
W65C02SOC-40 TSMC 180nm SOC Design History and Overview
WDC has been working with Dr. Yiyan Li to provide IP, boards, and support for a VLSI course that Dr. Li is creating at Fort Lewis College. This course will tape out a design on the TSMC 180nm technology. WDC has designed the W65C02SOC-40 microcontroller for use in Dr. Li’s course, and we feel that this same solution can be used in courses worldwide. We feel that using this design, professors can create a course that brings more value to their students and institutions. Students and professors will be able to work with their own EDA tool design flow in addition to WDC’s tool design flow, software development tools, and technology. In addition, WDC is partnering with Cadence (EDA design tools), TSMC (wafer foundry), and Muse Semiconductor (MPW services) for a complete tapeout of a SOC.
The W65C02SOC-40 is an 8–bit microcontroller with WDC’s W65C02S CPU, VIA, ACIA, IP along with open source I2C, SPI modules. In support of the IP, WDC has the MyMENSCH Rev-C board for emulation, the W65C02PRO board for adding modules to MyMENSCH, and the W65C02SOC-40TEB for the testing and evaluation of the SOC device that is created during the course. The W65C02SOC-40 datasheet contains information about the microcontroller, the PRO board, and the TEB board.

The course roadmap defines a learning experience that will provide students with real-world VLSI experience. It also takes into consideration the seven student learning outcomes that are part of ABET accreditation (1. Solve problems; 2. Design; 3. Communicate [writing and oral]; 4. Ethics and economics; 5. Teamwork; 6. Experimentation; 7. Life-long learning [acquire new knowledge]).
I’m interested, what are the next steps?
Please Contact Us if you are a professor at a College or University and are interested in integrating our IP into your existing or new course offering.
Note that each Educational institution must have an NDA with TSMC that is coordinated through Muse Semiconductor for tapeout services through TSMC.
