Migrating Renesas’ MCUs from 130nm (MF3) to 110nm (MF4) Technology

Renesas, a pioneer in microcontroller technology, continues to push the boundaries of innovation with our advanced process technologies. One significant advancement is the migration from the MF3, utilizing the 130nm process technology, to the MF4, harnessing the power of the 110nm process technology. This transition brings a host of benefits, including improved performance, power efficiency, cost optimization, and enhanced features. Let's dive deeper into the advantages of migrating to the 110nm MF4 technology and explore how it unlocks new possibilities for developers.

The MF4 leverages the advanced 110nm process technology, offering a significant leap forward from the 130nm technology used in the MF3-based MCUs. With a smaller node size, the 110nm process enables higher transistor density, leading to increased integration and improved system performance. Developers can expect enhanced functionality, higher processing power, and improved energy efficiency in their designs.

One notable improvement in the MF4 process technology is the adoption of Embedded SuperFlash (ESF3) flash cell technology, building upon the foundation of ESF2. This advancement translates into faster read speeds, efficient programming and erasing operations, and improved data integrity. The result is smoother operation and improved system performance, allowing developers to create reliable and efficient flash memory-based solutions.

Transferring to the MF4 technology brings substantial power efficiency gains. The combination of the advanced 110nm process technology and optimized design techniques results in reduced power consumption. This is particularly beneficial for battery-operated or power-constrained applications, as it extends battery life and reduces energy costs. Developers can create energy-efficient solutions without compromising on performance, making the MF4 technology an ideal choice for a wide range of applications.

Cost optimization and enhanced peripherals are crucial aspects of any MCU migration, and the MF4 technology excels in this area. The smaller node size of the 110nm process technology allows for higher chip yield per wafer, the ability to add enhanced IP, and making it more cost and feature optimized. Furthermore, the improved integration and performance capabilities of the MF4 technology eliminate the need for additional components or external devices, further driving down system costs. This cost optimization, combined with advanced features such as higher memory capacities, improved communication interfaces, and enhanced peripheral integration, empowers developers to create sophisticated applications while staying within budget.

Renesas' commitment to longevity ensures that the MF4-based devices, built on the advanced 110nm process technology with ESF3 flash cell technology, provide a future-proof solution. With long-term support and compatibility guaranteed for at least the next 15 years, developers can have confidence in the availability, reliability, and compatibility of their designs. This commitment gives peace of mind and ensures that the MF4-based MCU is a solid choice for long-term projects.

MF4-based MCUs offer several advantages in terms of IP area size and read speed. Here are the key differences:

  • IP Area Size: When migrating from MF3 to MF4, there is a reduction in IP area size. The IP area size refers to the size of the intellectual property (IP) components integrated into the MCU. In the case of a 512KB Flash area size, the MF4 MCU achieves a 30% reduction in size compared to MF3, resulting in a smaller footprint. This size reduction can have benefits in terms of overall system integration and cost efficiency.
  • Read Speed: The MF4-based MCU offers an improvement in read speed compared to the MF3 process technology-based MCU. While the MF3-based MCU has a read speed of 32MHz, the MF4-based MCU provides a faster read speed of over 48MHz. This increased read speed enables quicker access to the MCU's memory, leading to faster execution of instructions and improved system performance.

From the 130nm to the 110nm Renesas' advanced process technology opens up new possibilities for developers. With improved performance, power efficiency, cost optimization, and enhanced features, the MF4 technology enables developers to unlock the full potential of their applications. Embrace the migration to the 110nm and embark on a journey of innovation, efficiency, and success in the world of microcontrollers.
