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 Japanesesemiconductor manufacturer headquartered inTokyo,Japan, initially incorporated in 2002 asRenesas Technology, the consolidated entity of the semiconductor units ofHitachi andMitsubishi excluding theirdynamic random-access memory (DRAM) businesses,[4] to whichNEC Electronics merged in 2010, resulting in a minor change in the corporate name and logo to as it is now.[5]
In the 2000s to early 2010s, Renesas had been one of the six largestsemiconductor companies in the world.[6]
Ranked 16th in semiconductor company sales in 2023, Renesas holds the 2nd highest sales in Japan as of 2024. In the automotive MCU market share rankings, Renesas ranked second, following Infineon Technologies (as of 2024). In the overall MCU market share rankings, it ranks third, following NXP Semiconductors and Infineon Technologies (as of 2024).
The brand Renesas is a contraction of "Renaissance Semiconductor for Advanced Solutions".[4]
Renesas Electronics started operation in April 2010, through the integration ofNEC 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 chipjoint venture ofHitachi andMitsubishi, with their ownership percentage of 55 and 45 in order.[9] The DRAM businesses of the three had become part ofElpida Memory, which went bankrupt in 2012 before being acquired byMicron 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 fromiSuppli.[11]
In December 2010, Renesas Mobile Corporation (RMC) was created by integrating the Mobile Multimedia Business Unit of Renesas with the acquiredNokia Wireless Modem Business Unit.[12]
In 2011, Renesas Electronics was adversely affected by the2011 Tōhoku earthquake and tsunami[13] and flooding inThailand. In 2012, the company, which had about 50 thousand employees of 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.[17] 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 themicrocontroller and analog and power chips for automotive and industrial uses, plant improvements, and corporate acquisitions.[18]

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.[55] 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,[56] to this end the core offered a novel low power mode of operation called “snooze mode”[57] 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.
The RX, an acronym for Renesas Xtreme, is the family name for a range of 32-bitmicrocontrollers developed by Renesas, as opposed to the H family and the MC family, launched by Hitachi and Mitsubishi respectively.[58][59]
The RX family was launched in 2009 by Renesas Technology with the first product range designated the RX600 series[60] 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[61] and also through enhanced performance versions.
The RA, an acronym for Renesas Advanced, is the family name for a range of 32-bitmicrocontrollers with Arm Cortex processor cores.[62] 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[63] for the users.

The Renesas RZ family is a high-end 32 & 64 bitmicroprocessors[64] that is designed for the implementations of high resolution human machine interface (HMI), embedded vision, real-time control, andindustrial Ethernet connectivity.[65] It supports 6 protocols:PROFINET RT/IRT,EtherNET/IP, POWERLINK, Modbus/TCP, EtherCAT, TSN, 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.[65]
