This process technology refers to the size of the transistors and interconnects used in manufacturing the MCU. Renesas’ adoption of the Split-Gate MONOS (SG-MONOS) technology in our automotive microcontroller units (MCUs) brings forth a multitude of benefits that set them apart in the industry. With over 30 years of experience in charge trapping type Non-Volatile Memory (NVM) production, Renesas has established itself as a leader in delivering excellent features and reliability. Renesas has utilized charge trapping type NVM technology to achieve faster performance and integrate large flash memory in our MCUs. This technology enables efficient data storage and retrieval, resulting in quicker access times and improved system performance. We have also integrated large flash memory capacities into our MCUs, reducing the need for external memory devices and enhancing the MCU’s capabilities.
One standout advantage of the 40nm process technology is its world-class high-speed random read performance, positioning Renesas as the industry leader in this aspect. The ability to access data quickly and efficiently is crucial in many applications, and Renesas’ 40nm MCUs deliver unmatched performance in this regard. Furthermore, our 40nm process technology offers the fastest flash access without the need for “Wait States.” This means that data can be accessed rapidly, leading to enhanced system responsiveness and reduced latency. This advantage is particularly significant in real-time applications where quick data access is critical for seamless operation.
Renesas’ 40nm process technology also boasts a discrete storage node architecture based on charge trapping mechanisms. This design ensures high reliability and scalability, allowing the MCUs to withstand demanding operating conditions and adapt to evolving industry requirements. Additionally, the integration of thin nitride film storage (SiN) technology enables a low-profile cell design, making the MCUs compatible with advanced logic processes.
The implementation of Split-Gate (SSI) programming, which enables low-power programming operations, contributes to energy efficiency, reducing power consumption and extending battery life in portable devices. To further enhance performance and power efficiency, Renesas has incorporated low voltage word-line drive and eliminated high voltage in the read access path. These optimizations result in high-speed random read operations exceeding 400MHz while maintaining a small area size. The combination of high performance, low power consumption, and compact size makes Renesas’ 40nm MCUs ideal for a wide range of applications.
The Renesas’ 40nm technology brings significant advantages to a diverse set of industrial, consumer, and automotive applications. Amongst others, some of the leading advantages include in-charge trapping type NVM production, world-class high-speed random read performance, fastest flash access, high reliability, scalability, and optimized circuit design.
