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 in sleep-disable state. If CAN cell is sleep-enabled for wake up, an additional 60uA 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

running means that “Forced Wake up” and “cyclic Sense” and “Software Watchdog in stop mode” are not activated.

Vdd1 (external 5V output for MCU supply). Idd1 is the total regulator output current. Vdd specification with external capacitor. Sta-

bility requirement: C>47uF ESR < 1.3 ohms (tantalum capacitor)

In reset, normal request, normal and standby modes.

Measures with C=47uF Tantalum.
