Diosdado Banatao, a native of Iguig, Cagayan and an electrical engineering graduate from Mapua Institute of Technology in Manila is credited for eight major contributions to the Information Technology. Banatao is most known for introducing the first single-chip graphical user interface accelerator that made computers work a lot faster and for helping develop the Ethernet controller chip that made Internet possible. In 1989, he pioneered the local bus concept for personal computers and in the following year developed the First Windows accelerator chip. Intel is now using the chips and technologies developed by Banatao. He now runs his own semiconductor company, Mostron and Chips & Technology, which is based in California’s Silicon Valley.
He worked on the following technologies as have several hundred other engineers and does not claim having invented or innovated any of these technologies.
1.First single-chip, 16-bit microprocessor-based calculator (while at Commodore in 1976. Note: The first single-chip 16-bit microprocessor was the 1976 TMS 9900 by Texas Instruments. Texas Instruments also came up with the first pocket calculator in 1972. (Was Commodore the first to come up with the single-chip 16-bit calculator?)
2.First 10-Mbit Ethernet CMOS with silicon coupler data-link control and transreceiver chip; got 3Com into the Ethernet PC add-in card business (while at Seeq in early 1980s)
3.First system logic chip set for the PC-XT and the PC-AT (while at Mostron in 1984 and Chips and Technologies in 1985)
4.First enhanced graphics adapter chip set (while at Chips and Technologies in 1985)
5.Pioneered local bus concept for PC (while at S3 in 1989)
6.First Windows Graphics accelerator chip (while at S3 in 1990)- This is debatable
He is a managing partner of Tallwood Venture Capital. Prior to Tallwood he was a venture partner with the Mayfield Fund. He has served on the board of directors and as chairman of several emerging companies, including Marvell Technology Group, SiRF (acquired by CSR plc), NewPort Communications (acquired by Broadcom), and Cyras Systems (acquired by Ciena Corporation).
Banatao holds a Bachelor of Science degree in Electrical Engineering from Mapua Institute of Technology in the Philippines and a Master of Science degree in Electrical Engineering and Computer Science from Stanford University.
Dado Banatao is now a multimillionaire investor. He invested in a lot of networking companies that were eventually sold before he joined the venture capital firm Mayfield Fund in 1998. After two years, the company offered him to promote to a general partner but Dado refused it and instead decided to start his own venture capital firm named Tallwood Venture Capital with a capital of US$300 million, all of which came from his own pocket. He then believed that independence is more important than security.
Today Dado Banatao manages several businesses. His Cielo Communications is developing the vertical cavity surface emitting laser or Versel, which speeds the transmission of data along optical lines. His SIRF Technology is designing a chip for a global positioning system which utilizes satellites to locate objects. His Marvell Technology had a highly successful public offering with the stock price soaring more than 300% during its first day of trading. He has proven to be a master investor and venture capitalist. He invests, oversees, and sells several companies that include Cyras Systems acquired by Ciena; Newport Communications acquired by Broadcom; Acclaim Communications acquired by Level One; Stream Machines acquired by Cirrus Logic; Marvell Technology Group and New Moo software.
He has more than three homes in the US, including resort properties in Lake Tahoe and Sonoma San Francisco. From his childhood roots of walking barefoot, he now drives his high-performance luxury cars and he flies his own fast jets. Yet despite these blessings, Dado Banatao still contributes to the society and to the country. His Banatao Filipino American Fund assists Northern California high school students of Filipino heritage in pursuing a college education in engineering. Aside from this, he also went back to his childhood town of Iguig in Cagayan Valley where he built a computer center at his grade school making it the only public school with the most modern computer network.
A proud Filipino, definitely an achiever…
