Conclusions• Automotive industry is enjoying exciting times,

momentum increasing for vehicle electrification

• Adding e-machines brings the need for torque management and energy optimization.

• Traditional microcontroller solutions will not keep pace with the demands from electrification

• New innovative microcontrollers from NXP are being developed to meet the demands

• These new microcontrollers, with new virtualisationfeatures, bring new ECU consolidation possibilities
