Costa Mesa-based chipmaker ISC8 Inc. has filed for Chapter 11 bankruptcy protection.
The company has more than 100 creditors and liabilities between $10 million and $50 million, according to court documents filed in the U.S. Bankruptcy Court for the Central District of California, Santa Ana division.
ISC8, which employs about 65 local workers, has $1 million to $10 million in assets.
The 12th-largest chipmaker here had been one of the fastest growing private companies in Orange County based on revenue as recently as 2012. It topped $14.6 million in sales for the 12 months ended June 2012, but struggled to maintain profitability. It lost about $17 million in that same time frame.
The company changed its name in 2011 from Irvine Sensors Corp. in a rebranding effort to highlight its technology for fighting cyber attacks and other possible security breaches.
ISC8 is best known for making stacks of memory chips, miniature cameras and night-vision goggles.
The company, established in 1974, was traded on the low profile Pink Sheets.
Its market share has been erased since eclipsing $13 million a few years ago.
