Renesas Sets a New Performance Standard
Demand for higher compute power in compact, energy-efficient packages is driving the next wave of embedded innovation. Renesas answers this call with the RA8P1 microcontroller family, built around the Arm Cortex-M85 CPU and the Arm Ethos-U55 microNPU (neural processing unit). Running at up to 1 GHz, it delivers up to 1,000 DMIPS of general-purpose performance plus AI-specific acceleration—all under a single chip.
Blending DSP and AI in One Chip
The Arm Ethos-U55 microNPU inside the RA8P1 adds up to 1.6 TOPS (trillions of operations per second) of AI inference power. That means you can run voice, vision, or anomaly detection models right at the edge. It’s a flexible setup. The Cortex-M85 core handles control and DSP tasks, while the microNPU tackles neural network workloads. You avoid the latency and security risks of sending data off-chip.
High Performance, Low Power
Benchmarks show the RA8P1 family outpaces previous Renesas MCUs by over 2.5× in identical power modes. It clocks in at 1000 DMIPS compared to 375 DMIPS on the earlier 480 MHz models. What’s more, it achieves up to 45 % lower power consumption thanks to a refined 40 nm process and smart power domain architecture. You get more work done for every milliwatt.
Robust Memory and Storage
Each RA8P1 part offers up to 9 MB of on-chip flash and 2.5 MB of SRAM. That lets you store larger AI models and richer firmware stacks without resorting to external memory. A built-in QSPI flash controller also supports quad-SPI memory expansion if you ever need more storage. With this much local memory, code size and data handling become far simpler.
Security You Can Trust
Security is built in from the ground up. The RA8P1 family features Arm TrustZone to isolate secure and non-secure tasks. A dedicated Secure Crypto Engine accelerates AES, SHA, and other ciphers. There’s a hardware true random number generator (TRNG) for strong entropy. In short, you can lock down your application, firmware updates, and on-chip AI models against tampering and eavesdropping.
Versatile Peripherals and Connectivity
You won’t run short on interfaces. RA8P1 parts come with USB Full Speed (with PHY), CAN FD for automotive and industrial networks, dual I2C, Quad SPI, and high-speed UART. On the analog side, four 1 Msps ADC channels, two comparators, and a DAC let you handle sensors and feedback loops. A DMA controller moves data around with minimal CPU intervention, freeing cycles for AI and control logic.
Built-In Development Ecosystem
Renesas backs the RA8P1 with a robust software and tooling package. The Flexible Software Package provides drivers, middleware, and example code for FreeRTOS, Micropython, and more. You’ll find full support for Arm Keil, IAR Embedded Workbench, and Renesas e^2 studio. A simulation environment lets you test AI models and control code before you ever power up hardware.
Ideal for Edge AI and IoT
From predictive maintenance in factories to smart wearables in healthcare, the RA8P1 shines where you need local intelligence. It’s perfect for:
• Factory automation and robotics
• Smart meters and grid monitoring
• Medical devices and patient monitoring
• Home appliances and security systems
• Vision-guided drones and AGVs
With on-device AI inference, you reduce cloud dependence, cut latency, and safeguard user data.
Voices from Renesas
Scott Rychecky, President of Renesas Americas, notes, “The RA8P1 family marks a leap forward in microcontroller design. By blending 1-GHz performance, AI acceleration, and industry-leading power efficiency, we’re empowering engineers to build smarter, more secure solutions right at the edge. This platform is a game-changer for any application that demands real-time decision making, robust security, and long battery life.”
Pricing and Availability
Renesas has already started sampling the RA8P1 series to key customers. Production units will be available later this quarter. Pricing starts at $3.50 per unit in 10,000-piece quantities. You can choose from several pin-count and memory configurations to match your project.
