Filipino‑American technology icon Diosdado “Dado” Banatao died on Christmas Day after a battle with a neurological disorder. He was 79 and would have turned 80 in May.
Banatao’s journey began in Iguig, Cagayan, where he was born to a rice farmer and a housekeeper. He studied electrical engineering at Mapua Institute of Technology in Manila before moving to the United States for graduate studies at Stanford University,where he earned a master’s degree in electrical engineering and computer science in 1972.
Early in his career, Banatao held engineering roles at several tech firms, including Boeing, National Semiconductor, and Intersil.While at Commodore International, he helped design a first‑of‑its‑kind single‑chip, 16‑bit microprocessor‑based calculator. His work later expanded to chip innovations that accelerated personal computers.
from Chips to Silicon Valley Powerhouse
In 1981, Banatao developed the first 10‑Mbit Ethernet CMOS chip while at Seeq Technology. He also contributed to the creation of a system logic chipset for IBM’s PC‑XT and PC‑AT, and helped popularize early graphics accelerators for PCs. His innovations are credited with delivering faster computer performance and broader consumer access to advanced graphics technology, later cited by industry observers and historians.
His influence extended beyond hardware. The Harvard Club of Southern California highlighted Banatao as a pioneer who brought GPS technology to consumers, underscoring his role in translating complex concepts into mainstream tech experiences.
Entrepreneurship, Venture Capital, and Mentorship
Banatao co‑founded Mostron in 1984, marking an early foray into chipset and electronics ventures. The following year, he helped launch Chips and Technologies, a graphics adapter company that Intel later acquired for roughly $430 million, underscoring Banatao’s impact on the PC graphics ecosystem.
In 1989, he founded S3 graphics, which advanced Windows accelerator chips and contributed to broader PC bus innovations. by 1993,S3 Graphics was among the era’s most profitable technology companies,a testament to Banatao’s ability to scale hardware breakthroughs into commercial success.
Transitioning to venture capital, Banatao established tallwood Venture in 2000, focusing on semiconductor startups and related technologies. During his Tallwood years,he encouraged portfolio companies to pursue international growth,a stance he described as increasingly essential as markets and costs shifted globally.
Banatao’s leadership and mentorship resonated throughout the industry. Colleagues described him as a catalyst who shaped early teams, offered steadfast counsel, and inspired founders to broaden their horizons.
Legacy, Recognition, and Philanthropy
Banatao’s work earned multiple honors, including the Pamana ng Filipino Award in 1997, the Asian Leadership Award in 1993, and the Ramon V. Del Rosario Award in 2018. Stanford’s asian American Activities Center inducted him into its Multicultural Alumni Hall of Fame in 2003.
Beyond awards, Banatao and his family supported education and mentorship through the Philippine Development Science and Technology Foundation (PhilDev), a nonprofit that offers scholarships, mentorship, and training for Filipino students in science and technology. The family encouraged donations to PhilDev in Banatao’s memory.
the Banatao Institute,named at the Center for Details Technology Research in the Interest of Society,was recognized as a hub for research and outreach tied to his mission of expanding access to technology and education. Industry peers also mourned his passing, noting how his ideas and generosity helped shape early tech ecosystems and future generations of engineers.
