A former SigmaTel Inc. executive has founded a new Austin semiconductor company and launched its first product after buying back SigmaTel assets.


CEO Gozie Ifesinachukwu, former general manager of SigmaTel's ICG business unit, said he reacquired the SigmaTel assets last year from Integrated Device Technology Inc. to form Tempo Semiconductor Inc. This month, the 16-person company introduced its first product — a low-power semiconductor for the audio market.


Tempo Semiconductor is one of the few developers of such audio products used with software drivers across several platforms including Windows, Android and Linux. It now claims 40 customers, Ifesinachukwu said.


He projects that Tempo will release three new products next year. In addition to the personal computer market, the company's technology is targeting the handheld and portable devices market.


Before Tempo Semiconductor, Ifesinachukwu was vice president of engineering at Austin-based Ambiq Micro Inc. and president of Stravelis Inc., according to his online profile.


Austin-based SigmaTel was once a high-flying tech company that developed so-called "system on a chip" electronics and software. Its audio products once dominated the personal computer and early-generation MP3 devices. In 2006, California-based IDT bought SigmaTel's audio business in a deal worth about $80 million.


Austin-based Freescale Semiconductor Inc. bought SigmaTel in 2008 for $110 million.
