One of a kind

OLEA® T222 is a member of OLEA family, the 1st Field Programmable Control Unit (FPCU) automotive qualified solution. FPCU is a new semiconductor architecture defined as a combination of the hardware flexibility of the AMEC® real-time Control Unit with the software flexibility of a standard processor into a single chip.

AMEC® integrates parallel data paths between acquisition and actuation peripherals and the Flexible Logic Unit (FLU), an automotive specific and robust embedded programmable logic with DSP resources. OLEA® T222 also benefits from SILant®, an ASIL-D functional safety integrated architecture. SILant® raises faults coverage and reliable countermeasures usually provided at chip level as high as application level and without compromising the performances.

FPCU removes software bottleneck by enabling software and hardware execution of high frequency and precise PWM control algorithm while limiting heat dissipation. Using Silicon Mobility's FPCU, user's control command can be programmed in hardware into FLU and delivers the following performances : 40x acceleration of data processing capabilities, Up to 20x faster hard real-time control loop and Up to 180x power consumption reduction.
