The RA8D1 family MCUs are available now, along with the FSP software. Renesas is also providing the RA8D1 Evaluation Kit which includes few example projects targeted at graphics applications.

The Key features of the RA8D1 MCUs family to handle the Graphic Display Solutions and Voice/Vision Multimodal AI Applications such as building automation, smart home, consumer, and medical applications.

The RA8 Series MCUs harness the potent Arm Cortex-M85 processor and Arm’s Helium™ technology, enabling remarkable performance gains up to 4 times faster than the Cortex-M7 core in tasks such as digital signal processing (DSP) and machine learning (ML). This heightened performance is a boon for graphic-intensive applications like high-resolution displays in smart home interfaces or medical imaging systems. Additionally, it greatly benefits neural network operations, making tasks like voice recognition in building automation systems or medical diagnostics more efficient.

Furthermore, the comprehensive security suite within these MCUs, including Arm TrustZone® technology, Renesas Security IP (RSIP-E51A), and Secure Boot with immutable first-stage bootloader, fortifies consumer electronics like home appliances or smart home devices against potential cybersecurity threats. The added security measures are also instrumental in safeguarding sensitive medical data or ensuring secure communication in building automation systems.

The new RA8D1 devices come packed with a suite of features targeted for high-resolution graphics applications. These include a powerful high-resolution graphics LCD controller equipped with parallel RGB and MIPI-DSI interfaces, specifically designed for seamless integration with LCD panels. Complementing this is a robust set of components: a 2D graphics drawing engine, a 16-bit camera interface (CEU), and multiple external memory interfaces to accommodate frame buffer storage and graphics assets. These devices are available in both 176 and 224-pin packages, offering flexibility in deployment.

What’s truly impressive is the integration of professional-grade graphics user interface software solutions from SEGGER emWin and Microsoft GUIX into the Renesas Flexible Software Package (FSP). This amalgamation not only enhances functionality but also streamlines development for users.

Renesas further extends support for the open-source Light and Versatile Graphics Library (LVGL) and maintains a robust network of graphics and AI ecosystem partners, ensuring a wide spectrum of support and resources for developers.

To facilitate seamless development, Renesas offers a comprehensive graphics evaluation kit inclusive of an LCD panel and camera module. This kit serves as a robust platform for developing a myriad of graphics applications. From industrial Human-Machine Interfaces (HMI) to video doorbells, patient monitors, graphics calculators, security panels, printer display panels, and appliance displays, these devices empower developers to innovate across various industries with top-tier graphics capabilities.

The RA8D1 Group MCUs Include An Array of Key Features That Make Them Stand Out in Their League

  • 480 MHz Arm Cortex-M85 core with Helium and TrustZone technologies for exceptional processing power.
  • Integrated 2MB/1MB Flash memory and 1MB SRAM (including TCM, 512KB ECC protected) for efficient data handling and storage.
  • Graphics peripherals supporting resolutions up to WXGA (1280×800) with parallel RGB and MIPI-DSI interfaces, a robust 2D drawing engine, 16-bit CEU camera interface, and a 32-bit external SDRAM interface for high-quality graphics rendering.
  • Comprehensive suite of peripherals including Ethernet, XSPI (Octal SPI) with XIP and DOTF, SPI, I2C/I3C, SDHI, USBFS/HS, CAN-FD, SSI, 12-bit ADC & DAC, comparators, temperature sensor, and timers for seamless integration with various interfaces.
  • Leading-edge security features such as cryptographic algorithms, TrustZone technology, Secure Boot, immutable storage, tamper resistance with DPA/SPA attack protection, secure debug, secure factory programming, and lifecycle management support for robust protection against threats.
  • Available in 176-pin LQFP and 224-pin BGA packages, offering flexibility in deployment and integration into diverse systems and designs.

The RA8D1 Group MCUs benefit from Renesas’ Flexible Software Package (FSP), streamlining application development with comprehensive infrastructure software. This package encompasses multiple RTOS, BSP, peripheral drivers, middleware, connectivity, networking, and security stacks, alongside reference software for complex AI, motor control, and cloud solutions. FSP enables seamless integration of legacy code and preferred RTOS choices, offering complete flexibility in development.
