Template:Nihongo is a Japanese semiconductor manufacturer headquartered in Tokyo. The name "Renesas" is a contraction of "Renaissance Semiconductor for Advanced Solutions." The company was established in 2002 as Renesas Technology through the merger of the semiconductor divisions of Hitachi and Mitsubishi Electric, excluding their DRAM businesses.<ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In 2010, Renesas Technology merged with NEC Electronics to form the current company and adopting its present name.<ref>Template:Cite news</ref>
Renesas was among the world's six largest semiconductor companies during the 2000s and early 2010s.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> As of 2023, it ranked 16th globally in semiconductor sales and second in Japan. In 2024, it ranked second in the automotive microcontroller (MCU) market behind Infineon Technologies, and third in the overall MCU market behind NXP Semiconductors and Infineon.
History
Renesas Electronics was established in April 2010 through the merger of Renesas Technology and NEC Electronics.<ref>Template:Cite news</ref> Renesas Technology had been formed in 2003 as a joint venture between Hitachi and Mitsubishi Electric, combining their non-DRAM semiconductor businesses.<ref name=":0" /><ref>Template:Cite news</ref> NEC had earlier spun off its semiconductor division as NEC Electronics in 2002.<ref>Template:Cite news</ref><ref>Template:Cite news</ref> The companies had previously separated their DRAM operations into Elpida Memory, which filed for bankruptcy in 2012 and was acquired by Micron Technology.<ref>Template:Cite news</ref>
In December 2010, Renesas Mobile Corporation was formed by integrating Renesas’s mobile business with assets acquired from Nokia.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> However, the company later exited the mobile sector, transferring LTE assets to Broadcom in 2013 and dissolving the subsidiary in 2014.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite news</ref>
The 2011 Tōhoku earthquake and flooding in Thailand severely impacted Renesas’s operations.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> A major restructuring followed, involving the sale of domestic factories and a capital infusion from the Innovation Network Corporation of Japan (INCJ), which became the company's largest shareholder in 2013.<ref>Template:Cite news</ref><ref>Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Renesas returned to profitability in fiscal year 2013.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
From 2016 onward, Renesas embarked on a series of acquisitions to strengthen its automotive and industrial semiconductor portfolio. It acquired Intersil in 2017<ref>Template:Cite news</ref> and Integrated Device Technology (IDT) in 2019.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In 2021, it purchased Dialog Semiconductor for $5.9 billion,<ref>Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> followed by additional acquisitions including Celeno Communications,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Reality AI,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and Steradian Semiconductors.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
In March 2021, a fire at the Naka Factory temporarily disrupted production, but operations resumed the following month.<ref name=":2">Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The company also reopened its Kofu fabrication facility to support power semiconductor production, with operations expected to begin in 2024.<ref name=":3" />
Renesas continued its expansion through 2023 and 2024 with the acquisitions of Panthronics,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> gallium nitride chipmaker Transphorm,<ref>Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and PCB design software firm Altium.<ref>Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It also signed a long-term silicon carbide wafer supply agreement with Wolfspeed and entered a strategic partnership with Vietnamese EV maker VinFast.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="RE2609222">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
In April 2023, Renesas was added to the Nikkei 225 index,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and in December 2022, it received the “Outstanding Asia-Pacific Semiconductor Company Award” from the Global Semiconductor Alliance.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Products
Microcontrollers
RL78 family
RL78 is the family name for a range of 16-bit microcontrollers. These were the first new MCU to emerge from the new Renesas Electronics company after the merger of NEC Electronics and Renesas Technology.<ref name="Business Wire 2010"> Template:Cite press release</ref> These microcontrollers incorporate the core features of the NEC 78K0R (150 nm MF2 flash process) and many familiar peripherals from legacy Renesas R8C microcontrollers. The RL78 core variants include the S1, S2, and S3 type cores which evolved from the NEC 78K0R core. The basic S1 core support 74 instructions, the S2 core adds register banking and supports 75 instructions, while the S3 core adds an on-chip multiplier / divider / multiple-accumulate and supports 81 instructions.
The RL78 was developed to address extremely low power but highly integrated microcontroller applications,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> to this end the core offered a novel low power mode of operation called “snooze mode”<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> where the ADC or serial interface can be programmed to meet specific conditions to wake the device from the extreme low power STOP mode of 0.52uA.
RX 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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The RX family was launched in 2009 by Renesas Technology with the first product range designated the RX600 series<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and also through enhanced performance versions.
RA family
The RA, an acronym for Renesas Advanced, is the family name for a range of 32-bit microcontrollers with Arm Cortex processor cores.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> for the users.
