Key Players
Zonal reference systems help engineers assess power distribution alongside data functions. NXP’s CoreRide Z248 combines these within a compact ECU design. It remains listed as preproduction. [4] The protection component must fit both the circuit and the behavior expected by the vehicle controller.
