Renesas Begins Shipping RA8D2 Industrial IoT MCUs
Renesas' new RA8D2 series of microcontrollers are now shipping, targeting industrial and Internet of Things applications. The MCUs are optimized for enhanced security, connectivity, and performance requirements in these sectors. The release is part of a broader trend of MCU vendors integrating more specialized features for specific vertical markets.
- The RA8D2 series is among the first to be built around the Arm Cortex-M85 processor, capable of running at 1 GHz and achieving a performance benchmark of over 7300 CoreMarks. - The Cortex-M85 core features Arm's Helium technology, a vector extension that can boost digital signal processing (DSP) and machine learning (ML) performance by up to four times compared to MCUs with a Cortex-M7 core. - Some configurations employ a dual-core architecture, combining the 1 GHz Cortex-M85 with a 250 MHz Cortex-M33 processor, which allows for efficient partitioning of demanding tasks and real-time operations. - These MCUs utilize embedded Magnetoresistive RAM (MRAM) instead of traditional Flash for code and data storage, offering faster write times, higher endurance, and lower power consumption. - For advanced human-machine interface (HMI) applications, the RA8D2 includes a 2D graphics drawing engine and a graphics LCD controller supporting up to WXGA (1280x800) resolution displays via MIPI-DSI and parallel RGB interfaces. - Connectivity options tailored for industrial environments include a Gigabit Ethernet controller with a 2-port Time-Sensitive Networking (TSN) switch, USB 2.0, and CAN FD interfaces. - To support vision and voice AI at the edge, the devices are equipped with MIPI CSI-2 and parallel camera interfaces, as well as I2S and PDM audio interfaces for digital microphones. - Security is handled by the Cortex-M85's integrated Arm TrustZone for memory isolation, supplemented by Renesas' own security IP for cryptographic acceleration, secure boot, tamper protection, and immutable storage.
