ARM automotive MCUs bring added safety

LONDON – Scaleo chip SA (Sophia Antipolis, France), a fabless chip company serving the automotive sector, has added safety features to its OLEA family of microcontrollers. The features, called SILant, provide compliance to ISO26262 ASIL D, the company said.

The OLEA range of microcontrollers are based on the 32-bit Cortex-R5 multiprocessor capable core from ARM Holdings plc (Cambridge, England) and are intended for use in powertrain, body control and driver-information applications.

SILant makes use of an asynchronous multicore architecture to increase security and incorporates three additional patented hardware safety mechanisms called: Asynchronous LockStep (ALS), Execution Flow Control (EFC) and Events Sequence Control (ESC). The hardware features are surrounded by safety infrastructure and a safety management unit offers fault detection and management.

The OLEA architecture supports the segregation of safety-critical and non-safety-critical functions while allow mutual existence within the same MCU.

SILant is available for evaluation within OLEA prototype boards for selected customers.
