Renesas Electronics Corporation (ルネサス エレクトロニクス株式会社 Runesasu Erekutoronikusu Kabushiki Gaisha ) TYO: 6723 is a Japanese semiconductor manufacturer headquartered in Tokyo. It has manufacturing, design and sales operations in around 20 countries. Renesas is one of the world's largest manufacturers of semiconductor systems for mobile phones and automotive applications. It is the world's largest manufacturer of microcontrollers and the second largest manufacturer of application processors. Renesas is also known for LCD drivers, RF ICs, mixed-signal integrated circuits and system-on-a-chip semiconductors.
"Renesas" is an invented name and a contraction of Renaissance Semiconductor for Advanced Solutions.
Renesas Electronics started operation in April 2010, through the integration of NEC Electronics Corporation and Renesas Technology Corporation. NEC Electronics was established in November 2002 by a spin-off of the semiconductor operations of NEC. Renesas Technology was established on April 1, 2003, as a joint venture of Hitachi, Ltd. (55%) and Mitsubishi Electric (45%).
In April 2009, Renesas Technology and NEC Electronics reached a basic agreement to merge by around April 2010.
On April 1, 2010 NEC Electronics and Renesas Technology merged forming Renesas Electronics which became the fourth largest semiconductor company according to iSuppli published data.
In 2011, Renesas Electronics was adversely affected by the Great East Japan earthquake and flooding in Thailand, etc. Currently, the company is restructuring its business structure, including the sale and consolidation of its domestic plants, to turn around the company and compete better with aggressive overseas rivals to produce cheaper, smaller chips.
In December 2012, INCJ, Japan’s government-backed fund, and the key manufacturing clients decided to invest in the company. Through the investment, Renesas Electronics will secure 150 billion yen as fresh capital by September 2013 and use it for realizing the Smart Society through investment in the microcontroller and Analog & Power semiconductor development, plant improvements, automotive and industrial semiconductor solutions and corporate acquisitions.
Renesas Electronics' products include:
- System LSIs
- Discrete devices (diodes, Power MOSFETs, thyristors and triacs, transistors)
- Memory ICs (Flash, SRAM)
