note 1: Vdd1>4V, reset high, logic pin high level reduced, device is functional.
note 2: current measured at Vsup pin.
note 3: Device is fully functional. All modes available and operating, Watchdog, HS1 turn ON turn OFF, CAN cell operating, L0 and L1 inputs
operating, SPI read write operation. Over temperature may occur.
note 4: Excluding the CAN cell current. An additional 30uA typical must be added to specified value.
note 5: Oscillator running means “Forced Wake Up” or “Cyclic Sense” or “Software Watchdog” timer activated.
note 6: Vdd is ON with2mA typical output current capability.
