Functional Safety
ISO 26262 certified ready
The first company to do it
Silicon Mobility is the first company to offer an ISO 26262 certified full stack automotive solution that includes ASIL-D certified OLEA® T222 FPCU chip, OLEA® APP – T222 INVERTER application (ASIL-D certified) and OLEA® COMPOSER development framework and OLEA® LIB Libraries (up to ASIL-D certified). Comprehensive safety work products are available for designers and functional safety managers, along with the certification report.
Today, OLEA® technology is a leader in enabling efficient control of the most critical applications such as the inverter and electric motor, DC-DC, and OBC.
With SILant® Technology
OLEA® T222 FPCU functional safety includes SILant®, a patented hardware technology embedded into the chip. SILant® integrates a safety architecture that goes beyond ASIL-D SEooC (Safety Element out of Context) objectives. More importantly, OLEA® T222 FPCU enables to cover faults at application level with flexible and safe hardware. OLEA® T222 FPCU is qualified AECQ-100 Grade 1.
Benefits:
- Safety at application level with H/W acceleration
- Enables ASIL-D designs
- Saves CPU processing power
- Enables software code simplification
- Shortens the fault reaction handling time interval
- Supports system scalability and reuse
- Saves development efforts from specification to assessment
Safety at all levels
OLEA® APP – T222 INVERTER is a motor control application software for OLEA® T222 FPCU, enabling best-in-class control of electrified powertrains. Built as a software platform to control a wide variety of technologies and topologies, OLEA® APP – T222 INVERTER allows high-performance, real-time, and safe control of advanced power electronics and electric motors.
