IVDD

Total current into VDD/VDDA power lines (source)(1)

1. All main power (VDD, VDDA) and ground (VSS, VSSA) pins must always be connected to the external power

supply, in the permitted range.

IVSS

Total current out of VSS ground lines (sink)(1)

IINJ(PIN) (2)

2. Negative injection disturbs the analog performance of the device. See Note: on page 66.

Injected current five volt tolerant pins(3)

3. 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 5 for maximum allowed input voltage values.

−5/+0

Injected current on any other pin(4)

4. 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 5 for maximum allowed input voltage values.

± 5

ΣIINJ(PIN)

Total injected current (sum of all I/O and control pins)(5)

5. 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).
