In recent years, Renesas has made significant efforts in the MCU sector, continuously launching new MCUs.In fact, I have previously shared many articles about Renesas MCUs, including the newly launched MCU, such as: the ultra-low power microcontroller RA4L1. Additionally, I have shared an article: The Rise of Renesas MCUs in Recent Years.
Recently, I discovered that Renesas quietly launched a “world’s most powerful MCU” RA8P1 series MCU on their official website.Reference link:
https://www.renesas.cn/zh/products/ra8p1
However, the RA8P1 series has not yet been officially announced, and the RA8 section on the Renesas website has not been updated with the RA8P1 series:
The official documentation is still being updated, and I believe an official announcement will be made soon.
Highlights of the RA8P1 Series MCU
1. Core
As of June 2025, the most powerful MCU core from Arm is Cortex-M85, and the RA8P1 series MCU adoptsCortex-M85 core.

As of June 2025, the most powerful MCU core from Arm is Cortex-M85, and the RA8P1 series MCU adopts the latestCortex-M85.
The RA8P1 series is Renesas’ first 32-bit AI acceleration MCU equipped with a high-performance Cortex-M85 and Helium™ vector extension, integrating the Ethos-U55 NPU.
2. Clock Speed and Performance
Compared to other models in the RA8 series like M1 and D1 (with a clock speed of 480MHz), the RA8P1 has a significant increase in clock speed, reaching 1GHz.
Currently, there are very few MCUs on the market with a clock speed exceeding 1GHz, such as NXP’s iMX RT117 with a clock speed of 1GHz, but it has a Cortex-M7 core.
The RA8P1 series achieves 256 GOPS* of AI performance, over 7300 CoreMarks of breakthrough CPU performance, and advanced artificial intelligence (AI) capabilities through a single chip.
3. Process Technology
RA8P1 series is manufactured using a 22nm ULL process, while RT1170 uses a 28nm FD – SOI process technology.
4. Dual-Core
The RA8P1 series adopts a combination of single and dual-core configurations. Currently, the official data sheet shows the announced single-core and dual-core models:
5. Peripherals
From the documentation and block diagrams, it is evident that the RA8P1 series has a rich set of peripherals with powerful key functions, including HMI, Gigabit Ethernet, 16-bit ADC analog, 32-bit timers, etc.
World’s “Strongest” MCU
The term strongest MCU here mainly refers to the overall performance.
Although NXP’s RT117 has a clock speed of 1GHz, its core is M7, which is completely an “era-crossing” product compared to M85.
At the same time, the powerful hardware of the RA8P1 can handle current AI functions, such as: voice, vision, and real-time analysis AI scenarios without any issues (other MCUs in the same category do not have such strong AI capabilities).
Regarding pricing, the official reference price for two models is:$16.60578
