The Centro Nacional de Tecnologia Eletrônica Avançada S.A (CEITEC - National Center for Advanced Electronic Technology) is a Brazilian technology center specialized in project development and fabrication in microelectronics, i.e. integrated circuits, or "chips". This center is one of the agents for the Brazilian Microelectronics Program (PNM - Programa Nacional de Microeletrônica).

The main objective of CEITEC is to provide an incentive to the production of semiconductor components and microeletronics education. This project is part of the technology and industrial development policy of the federal Brazilian government. The initiative is a result of a partnership between governmental entities, universities, research centers and companies and will be operating in Porto Alegre, state of Rio Grande do Sul in a 13,650 m² facility divided into:

Chip do Boi is CEITEC S.A.’s first commercial product and is the first chip designed in Brazil by Brazilian engineers in a company that was home grown and home funded to reach volume production at a world-class semiconductor manufacturing facility. This IC device is used for cattle tracking – essentially an electronic cow ID. Embedded in an ear ring, the chip can be read within a distance of 50 cm. The chip was designed in entirely in Brazil and is competitively priced. This device is being manufactured at X-FAB Silicon Foundries in Germany.This company has been chosen by CEITEC to produce the Chip do Boi design at its facilities because X Fab CMOS 0.6 micron technology is the same that will soon be available in CEITEC’s own factory that will be the first of its kind in Latin America to manufacture RF analog/digital products. It can produce up to 100 million chips per year using 6-inch wafers.
