NOTES:
1 This parameter is meant for those who do not use quartz crystals or resonators, but instead use CAN oscillators in crystal
mode. In that case, Vextal – Vxtal ≥ 400 mV criteria has to be met for oscillator’s comparator to produce the output clock.
2 This parameter is meant for those who do not use quartz crystals or resonators, but instead use a signal generator clock to
drive the clock in bypass mode. In this case, for the oscillator’s comparator to produce the output clock, drive only the EXTAL
pin. Do not connect anything to any other oscillator pin.
3 This parameter is meant for those who do not use quartz crystals or resonators, but instead use CAN oscillators in crystal
mode to drive the clock. In that case, for the oscillator’s comparator to produce the output clock, drive one of the XTAL_IN or
XTAL_OUT pins. Do not connect anything to the other oscillator pins.
4 This parameter is meant for those who do not use quartz crystals or resonators, but instead use a signal generator clock to
drive the clock in bypass mode. In that case, for the oscillator’s comparator to produce the output clock, drive only the XTAL_IN
pin. Do not connect anything to any other oscillator pin.
5 Leakage current is measured with output drivers disabled and with pullups and pulldowns inactive.
6 Pullup current is measured at V
IL and pulldown current is measured at VIH.
7 See Table 7 for the typical drive capability of a specific signal pin based on the type of output driver associated with that pin as 8 All injection current is transferred to V
DD_IO/VDD_IO_MEM. An external load is required to dissipate this current to maintain the
power supply within the specified voltage range.
Total injection current for all digital input-only and all digital input/output pins must not exceed 10 mA. Exceeding this limit can
cause disruption of normal operation.
