Transcriptions

ASIX Electronics Corporation (Chinese: 亞信電子股份有限公司), founded in May 1995, a fabless IC design company located in the Hsinchu Science Park, Taiwan, specializing in industrial and embedded networking as well as I/O interface controller solutions.

Corporate history

ASIX Electronics Corp. was listed on Taiwan OTC Stock Exchange (3169.TWO) in 2009. In its early years, ASIX focused on PC networking chips. Between 1998 and 1999, the company entered the notebook networking chip market, achieving a leading position in the PCMCIA Ethernet controller segment. This success enabled the company to surpass the break-even point and move into profitability. Since 2000, ASIX has expanded into embedded and USB Ethernet controllers. In 2018, the company introduced Greater China’s first EtherCAT slave controller chip for industrial automation applications.

• In August 2011, ASIX Electronics acquired the I/O Connectivity product line of MosChip Semiconductor Technology Ltd., a publicly listed company in India. This product line included three series: PCIe bridge, PCI bridge, and USB bridge.
• On November 5, 2014, ASIX Electronics acquired 100% equity of Zywyn Corporation, a U.S.-based company, for USD 8 million.
• On December 16, 2020, Airoha Technology, a subsidiary of MediaTek Group, obtained a 20% stake in ASIX Electronics through a private placement of common shares.
