IVDD

Total current into VDD power line (source)

IVSS

Total current out of VSS ground line (sink)

IIO

Output current sunk by IR_TIM pin

(with high sink LED driver capability)

Output current sunk by any other I/O and control pin

Output current sourced by any I/Os and control pin

IINJ(PIN)

Injected current on true open-drain pins (PC0 and PC1)(1)

- 5 / +0

Injected current on five-volt tolerant (FT) pins(1)

Positive injection is not possible on these I/Os. A negative injection is induced by VIN<VSS. IINJ(PIN) must

never be exceeded. Refer to Table 12. for maximum allowed input voltage values.

- 5 / +0

Injected current on any other pin (2)

A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. IINJ(PIN) must

never be exceeded. Refer to Table 12. for maximum allowed input voltage values.

- 5 / +5

ΣIINJ(PIN)

Total injected current (sum of all I/O and control pins) (3)

When several inputs are submitted to a current injection, the maximum

ΣIINJ(PIN) is the absolute sum of the

positive and negative injected currents (instantaneous values).
