Renesas Electronics Company introduced the primary microcontroller (MCU) with embedded flash that integrates a hardware-based virtualization-assisted operate whereas sustaining the quick, real-time efficiency of the RH850 merchandise. This hardware-based virtualization help know-how can help as much as ASIL D degree of purposeful security, offering better ranges of system integration.

The RH850/U2A MCU is the primary member of Renesas’ cross-domain MCUs, a brand new era of automotive-control gadgets, designed to handle the rising must combine a number of functions right into a single chip to appreciate a unified digital management models (ECUs) for the evolving electrical-electronic structure (E/E structure).

Based mostly on 28 nanometer (nm) course of know-how, the 32-bit RH850/U2A MCU builds on key capabilities from Renesas’ RH850/Px Collection for chassis management and RH850/Fx Collection for physique management to ship improved efficiency and implement a virtualization-assisted operate to help operation in chassis/security, physique, area management and low-end/mid-range gateway functions.

To help the ASIL D degree required for chassis/security functions, the hardware-based virtualization help know-how permits prospects to implement a number of software program with totally different purposeful security ranges on the RH850/U2A MCU and run concurrently with out interference, whereas sustaining the real-time efficiency required to regulate the autos.

The evolution of recent E/E Structure is driving the pattern towards single ECUs that help a number of ECU capabilities for high-performance gadgets that may function throughout a number of utility areas. Beginning with the RH850/U2A, Renesas’ new collection of cross-domain MCUs will increase growth effectivity and reduces growth time to speed up linked and autonomous automobile growth methods, and we’re excited to guide the cost with virtualization and ASIL D help.

Key options of the brand new RH850/U2A MCU. That includes a mixture of excessive efficiency, on-chip safety, and community connectivity, the cross-domain RH850/U2A MCU is designed for the rigorous workloads of a number of automotive management functions together with physique, chassis/security, area management, and low-/mid-range gateways.

  • Quick real-time efficiency and hardware-based virtualization-assisted operate to hurry ECU integration in complicated ASIL D compliant automotive-control methods. The brand new automotive-control MCU is supplied with as much as 4 400-megahertz (MHz) CPU cores in a twin core lock-step construction. Every CPU core integrates a hardware-based virtualization-assisted operate, whereas sustaining the identical quick real-time efficiency offered by the RH850. To help ASIL D, the MCU contains self-diagnostic SR-BIST (Standby-Resume BIST) capabilities with minimized present fluctuation price. The hardware-based virtualization-assisted operate permits a number of software program methods with various ISO26262 purposeful security ranges to function independently with out interference throughout excessive efficiency. It additionally reduces the virtualization overhead to keep up real-time execution. This permits customers to combine a number of ECU capabilities right into a single ECU whereas sustaining security, safety, and real-time operation necessities.

  • Superior, safe OTA updates with massive flash reminiscence capacities. The demand continues to develop for MCUs with built-in massive capability flash reminiscence to help over-the-air (OTA) performance that mechanically and wirelessly updates ECU software program to regulate applications with out interrupting automobile operations. The RH850/U2A MCU is supplied with as much as 16 megabytes (MB) of built-in flash ROM and three.6 MB of SRAM, providing customers the pliability for future operate growth. The MCU contains safety capabilities that help Evita Gentle up by Evita Full for enhanced safety towards cyber-attacks, enabling the gadget to help protected and fast Full No-Wait OTA software program updates as safety necessities evolve. (The EVITA (E-safety Automobile Intrusion proTected Functions) undertaking is co-funded by the European Union to develop in-vehicle community security specs. Evita Full is the very best degree following Medium and Gentle.)

  • Expanded community connectivity for ADAS and autonomous driving methods. The RH850/U2A MCU can also be outfitted with an in depth set of networking interfaces, together with an SGMII-standard 1 Gbps Ethernet communications interface and a CAN-FD interface with as much as 16 channels, enabling the MCU to course of the massive quantities of sensor knowledge being generated by a number of sorts of sensors in ADAS and autonomous driving capabilities. This permits prospects to help future high-speed community capabilities and superior communications throughput necessities.

Renesas will exhibit the RH850/U2A MCU at embedded world, 26-28 February in Nuremberg, Germany. Samples of the RH850/U2A MCU shall be obtainable starting Q1 2020. (Availability is topic to vary with out discover.) Renesas additionally plans to offer each software program and a growth atmosphere for the RH850/U2A MCU as a part of the brand new cross-domain MCU portfolio.
