Renesas Electronics

Renesas Electronics Corporation (ルネサス エレクトロニクス株式会社, Runesasu Erekutoronikusu Kabushiki Gaisha) is a Japanese semiconductor manufacturer headquartered in Tokyo, Japan, initially incorporated in 2002 as Renesas Technology, the consolidated entity of the semiconductor units of Hitachi and Mitsubishi excluding their dynamic random-access memory businesses,[3] to which NEC Electronics merged in 2010, resulting in a minor change in the corporate name and logo to as it is now.[4]

In the 2000s, Renesas had been one of the six largest semiconductor companies in the world.[5] As of 2014, it was the world's largest automotive semiconductor maker,[6] and the world's largest maker of microcontrollers. The company also has presences in the markets of analogue and mixed-signal integrated circuits, memory devices, and SoCs.

The brand Renesas is a contraction of Renaissance Semiconductor for Advanced Solutions.[3]

History

Renesas Electronics started operation in April 2010, through the integration of NEC Electronics, established in November 2002 as a spin-off of the semiconductor operations of NEC with the exception of the DRAM business,[7][8] and Renesas Technology established on April 1, 2003, the non-DRAM chip joint venture of Hitachi and Mitsubishi, with their ownership percentage of 55 and 45 in order.[9] The DRAM businesses of the three had become part of Elpida Memory, which went bankrupt in 2012 before being acquired by Micron Technology.[10]

A basic agreement to merge was reached by April 2010 and materialized on the first day, forming the fourth largest semiconductor company by revenue according to an estimation from iSuppli.[11]

In December 2010, Renesas Mobile Corporation (RMC) was created by integrating the Mobile Multimedia Business Unit of Renesas with the acquired Nokia Wireless Modem Business Unit.[12]

In 2011, Renesas Electronics was adversely affected by the 2011 Tōhoku earthquake and tsunami[13] and flooding in Thailand. In 2012, the company, which had manufacturing, design and sales operations in about 20 countries in 2011,[14] decided to restructure its business, including the sale and consolidation of its Japanese domestic plants, to become profitable.[15][16] In December 2012, INCJ, a Japanese public-private fund, and several key clients decided to invest in the company. Through the investment, Renesas aimed to secure 150 billion yen as fresh capital by September 2013 and make use of it for investment in development of the microcontroller and analog and power chips for automotive and industrial uses, plant improvements, and corporate acquisitions.

In January 2013, Renesas transferred some of its back-end plants to J-Devices.[17]

In September 2013, Broadcom acquired most of Renesas Mobile Communication.[18]

With the allotment of third-party shares to the nine investors completed in September 2013, INCJ became the largest shareholder in the company.[19] Renesas announced its new business direction and issued its corporate presentation titled "Reforming Renesas” in October 2013.[20]

In the fiscal year ended in March 2014, Renesas recorded its first ever net profit since it started operation as Renesas Electronics Corporation in 2010.[21]

In July 2014, the subsidiary Renesas Mobile Communication was consolidated, after the company had decided to withdraw from the 4G wireless business.[22]

In September 2014, the sale of the display driver IC unit of Renesas to Synaptics has been completed.[23]

In September 2016, Renesas announced that it would acquire Intersil for $3.2 billion.[24] In February 2017, Renesas completed the acquisition.[25]

In April 2017, Renesas unveiled a self-driving concept car at a global developer conference, stating that it will start delivering a new line of products for self-driving cars in December 2017, as it takes on global giants such as Intel. The new technology acts as an onboard nerve center, coordinating and controlling vehicle functions.[26]

In September 2018, Renesas announced that it has agreed to buy IDT for $6.7 billion.[27] The acquisition was completed in March 2019.[28]

In 2020, Renesas announced its plans to wind down its production of diodes and the compound device.[29]

Products

The offerings of Renesas Electronics include:

The RX MCU family

The RX, an acronym for Renesas Xtreme, is the family name for a range of 32-bit microcontrollers developed by Renesas, as opposed to the H family and the MC family, launched by Hitachi and Mitsubishi respectively.[32][33]

The RX family was launched in 2009 by Renesas Technology with the first product range designated the RX600 series and targeting applications such as metering, motor control, human–machine interfaces (HMI), networking, and industrial automation. Since 2009 this MCU family range has been enlarged with a smaller variant the RX200 series and also through enhanced performance versions.

Key to the high performance of the microcontroller is the CISC architecture with high performance integrated flash memory enabling the central processing unit (CPU) to operate at very high frequency, 100 MHz, without requiring wait-states for the memory accesses resulting in performance up to 1.65 DMIPS/MHz.

The RA MCU family

The RA, an acronym for Renesas Advanced, is the family name for a range of 32-bit microcontrollers with Arm Cortex processor cores. The RA family's key features are the stronger embedded security, high-performance, and CoreMark ultra-low power operation. It also has a comprehensive partner ecosystem and Flexible Software Package[34] for the users.

The RZ Arm-based 32 & 64-bit family

The Renesas RZ family is a high-end 32 & 64 bit microprocessors that is designed for the implementations of high resolution human machine interface (HMI), embedded vision, embedded artificial intelligence (e-AI), real-time control, and industrial ethernet connectivity.[35] It supports 6 protocols: PROFINET, EtherNET/IP, POWERLINK, Modbus/TCP, EtherCAT, and Sercos III.

The family includes, RZ/A and RZ/G for HMI, RZ/T for high-speed real-time control, and RZ/N for the network. [36]
