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 functions are operating (All mode available and operating, Watchdog, HS1 turn ON turn OFF, CAN cell
operating, L0 to L3 inputs operating, SPI read write operation). Over temperature may occur.
Note 4: With CAN cell disabled. If CAN cell is enabled for wake up, an additional 100uA must be added to specified value.
Note 5: Oscillator running means “Forced Wake up” or “Cyclic Sense” or “Software Watchdog in stop mode” timer activated. Oscillator not run-
ning means that “Forced Wake up” and “cyclic Sense” and “Software Watchdog in stop mode” are not activated.
Vdd1 (external 5V output for MCU supply and internal CAN physical interface supply).
Idd1 is the total regulator output current. Iddcan is the internal CAN block supply current. Iout is Vdd1 external output current.
Idd1 = Iddcan + Iout.
Vdd specification with external capacitor C>1uF and ESR<1O ohm. No tantalum capacitor required.
