Silicon Mobility, an Intel Company, recently unveiled a one-chip solution, the OLEA U310 field programmable control unit (FPCU), that replaces up to six separate microcontrollers (MCUs) in powertrain domain and energy control for electric vehicles (EVs). This automotive system-on-chip (SoC) enables manufacturers to design software-defined EVs with greater performance, improved range and potentially lower production costs.

The second-generation FPCU chip is engineered to match the need for powertrain domain control in electrical architectures with distributed software. Using a hybrid and heterogeneous architecture, a single OLEA 310 FPCU can replace up to six standard MCUs in a system combination where it controls an inverter, a motor, a gearbox, a DC/DC converter and an on-board-charger.
The company claims it is the only complete solution combining hardware and software that enables real-time control of multiple and diverse EV power and energy functions simultaneously.
According to the company, early figures show that the OLEA U310 FPCU reduces costs and improves performance, providing up to a 5% improvement in energy efficiency, a 25% reduction in motor size and up to a 30× reduction in the size of passive components. The SoC solution also requires 35% less cooling.
The OLEA U310 is a 3× Cortex-R52 cores controller chip at 350 MHz, leveraging three key technologies. These are the advanced execution and events control (AxEC 2.0) with 2× flexible logic units (FLUs); the SILant 2.0 safety integrity level agent with a deterministic multi-core and multi-FLU cluster; and the flexible hardware security module (FHSM) sub-system dedicated to the cybersecurity of the FPCU and compliant to EVITA Full and ISO 21434.
The automotive SoC is ISO/SAE 21434 certified, ISO 26262 ASIL-D design-ready and AEC-Q100 Grade 1 compliant. Other features include 8 MB of P-Flash, 256 kB of D-Flash and 1 MB of SRAM as well as several interfaces, including CAN FD, CAN XL and Ethernet.
The OLEA U310 is currently available to select customers.
