Overview
Description
The RH850/U2B is Renesas' cross-domain microcontroller series, a new generation of high-end automotive-control devices, designed to address the growing need to integrate multiple applications into a single chip to realize unified electronic control units (ECUs) for the evolving electrical/electronic architecture (E/E architecture). Based on 28 nanometer (nm) process technology, the 32-bit RH850/U2B automotive MCU builds on key functions from Renesas’ RH850/Ex Series for engine control and RH850/Cx Series for xEV to deliver improved performance.
This automotive-control MCU is equipped with up to four 400 megahertz (MHz) CPU cores + up to three dual-core lock-step. Each CPU core integrates virtualization support and Quality-of-Service (QoS) for X-in-1 applications. The latest hardware support technologies realize the integration of multiple ASIL D SW-partitions into one ECU while ensuring Freedom-From-Interference between the concurrently running applications to meet the ISO 26262 ASIL D standard.
The MCU includes security functions fulfilling EVITA Full for enhanced protection against cyber-attacks, enabling the device to support safe and rapid full no-wait Over-the-Air (OTA) software updates as security requirements evolve.
And the MCU incorporates a stand-alone high-performance motor-control accelerator IP (EMU3S) that works in flexible conjunction with multiple dedicated motor-control timer structures like GTM v4.1 and TSG3. As a unique feature, the embedded motor position sensor interface RDC3X (covering resolvers as well as inductive position sensors) provides the option to achieve significant BOM-cost reduction because the usually required external RDC chipset may be omitted.
To enhance the performance level for real-time control the RH850/U2B will be partly equipped with the DFP (DR1000C), a RISC-V based parallel coprocessor IP with vector extension. The DR1000C is ideal for offloading heavy-load arithmetic processing designed to address the evolving performance demands of electric mobility (eMobility), autonomous driving, and next-generation E/E architectures, including their high-level demand in network security. The DR1000C is licensed from DENSO Corp. of Japan.
