Silicon Mobility, an Intel company, has launched it’s OLEA® U310 Field Programmable Control Unit (FPCU) as part of its next generation of OLEA FPCU Series. The OLEA U310 consolidates functionalities of multiple traditional microcontrollers into a single system on chip (SoC), which they say will lead to substantial benefits for electric vehicle (EV) manufacturers and consumers.
A first for the industry, it replaces up to six separate microcontrollers while simultaneously delivering real-time control of multiple and diverse power and energy functions and guaranteeing maximum safety integrity and future-proofed cybersecurity. The unique design allows original equipment manufacturers (OEMs) to break free from the conventions of EV domain controls and move to a highly integrated X-in-1 powertrain that delivers unmatched system performance.
The OLEA U310 is engineered to match the need for powertrain domain control in electrical architectures with distributed software. Built with a unique hybrid and heterogenous architecture it surpasses the capabilities of traditional microcontrollers. Up to 6 standard microcontrollers can be replaced by a single OLEA U310 in a system combination where the FPCU is controlling in parallel an inverter, a motor, a gearbox, a DC-DC converter and an on-board-charger. The SoC embeds multiple software and hardware programmable processing and control units while seamlessly integrating functional safety and cybersecurity into its core design. This allows OEMs to run multiple time-based applications while simultaneously executing multiple event-based control functions. OEMs and automotive tier 1s can design several variants of system integration with OLEA U310 including a combination of the following functions: traction inverter and electric motor control with gearbox, DC-DC converter control, power factor converter control, on board charger, air compressor for fuel cell, battery management system, thermal management system with high-voltage e-compressor control, and more.
The OLEA U310 is a three Cortex-R52 cores controller chip leveraging its strength from three technologies:
+ AxEC 2.0: The Advanced execution and Events Control is a data processing and real-time control unit based on programmable hardware and configurable peripherals supporting multiple parallel applications thanks to multi-Flexible Logic Units (FLU) clusters.
+ SILant 2.0: The Safety Integrity Level agent is a set of units and functionalities dedicated to the FPCU and the system functional safety ensuring ISO 26262 ASIL-D compliancy. This new generation has a deterministic multi-core and multi-FLU cluster which guarantees worst-case execution timing.
+ FHSM: The Flexible Hardware Security Module is a sub-system dedicated to the cybersecurity of the FPCU integrating encryption/decryption accelerators and is compliant to EVITA Full and ISO 21434. It is combined with a hardware programmable cluster to support unidentified threats and strengthen security.
