Silicon Mobility introduces single-chip solution for integrated powertrain domain control and energy management

Silicon Mobility, an Intel company that provides automotive semiconductor and software control solutions, has announced the OLEA U310 Field Programmable Control Unit (FPCU) as part of its next-generation OLEA FPCU series. The new OLEA U310 consolidates the functionalities of multiple traditional microcontrollers into a single system on chip (SoC).

The OLEA U310 is specifically engineered to match the need for powertrain domain control in electrical architectures with distributed software. 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 is designed to enable OEMs to run multiple time-based applications while simultaneously executing multiple event-based control functions.

OEMs and Tier 1 suppliers 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.

Specifications include:

  • 3x Cortex-R52 @ 350 MHz—2196 DMIPS
  • AxEC 2.0: 2x FLUs @ 175 Mhz—400 GOPS + 9.1 GMAC
  • SILant 2.0: Safe and Determinist Multi-Core/FLU
  • Flexible HSM: HW & SW EVITA Full
  • 8 MB of P-Flash, 256 kB of D-Flash, 1 MB of RAM
  • CAN FD, CAN XL, Ethernet
  • ISO 26262 ASIL-D design ready
  • ISO/SAE 21434
  • AEC-Q100 Grade 1
  • 292 BGA

The OLEA U310 is equipped with a complete software suite from Silicon Mobility, including: OLEA COMPOSER, a design framework that integrates with development tools throughout the V-Model design cycle, to accelerate the development process for OLEA FPCUs; and OLEA LIB, a software library that provides engineers with a modular set of pre-built, pre-tested functional blocks (reference and target models for MATLAB and Simulink) tailored to common powertrain control tasks.

OLEA U310 is available today to select customers.
