Renesas Electronics RH850/U2B Zone/Domain & Vehicle Motion MCUs

Renesas RH850/U2B Zone/Domain and Vehicle Motion MCUs are 28nm cross-domain automotive control microcontrollers featuring up to 8 cores x 400MHz, including virtualization support and Quality-of-Service (QoS). Equipped with the HW-support technologies, the RH850/U2B realizes the integration of multiple ASIL-D SW-partitions into one ECU (electronic control unit) while ensuring Freedom-From-Interference between the concurrently running applications to meet the ISO26262 ASIL-D standard. The RH850/U2B will be partly equipped with the ASIL-D capable DR1000C, a RISC-V-based parallel coprocessor IP with vector extension to enhance the performance level for real-time control. The DR1000C offloads heavy-load arithmetic processing.

The integrated and comprehensive Renesas solution for traction inverter control incorporates a stand-alone high-performance motor-control accelerator IP (EMU3S) that works flexibly with multiple dedicated motor-control timer structures like GTM v4.1 and TSG3. An embedded motor position sensor interface RDC3X (covering resolvers and inductive position sensors) provides the option to achieve significant BOM-cost reduction because the usually required external RDC chipset may be omitted.
