ΣIVDD

Total current into sum of all VDD power lines (source)(1)

1. All main power (VDD, VDDA, VDD33USB) and ground (VSS, VSSA) pins must always be connected to the

external power supplies, in the permitted range.

620

ΣIVSS

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

IVDD

Maximum current into each VDD power pin (source)(1)

IVSS

Maximum current out of each VSS ground pin (sink)(1)

100

IIO

Output current sunk by any I/O and control pin

ΣI(PIN)

Total output current sunk by sum of all I/Os and control pins(2)

2. This current consumption must be correctly distributed over all I/Os and control pins. The total output

current must not be sunk/sourced between two consecutive power supply pins referring to high pin count

QFP packages.

140

Total output current sourced by sum of all I/Os and control pins(2)

IINJ(PIN)(3)(4)

3. Positive injection is not possible on these I/Os and does not occur for input voltages lower than the

specified maximum value.

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 also to Table 20: Voltage characteristics for the maximum allowed input voltage

values.

Injected current on FT_xxx, TT_xx, RST and B pins except PA4,

PA5

−5/+0

Injected current on PA4, PA5

−0/0

ΣIINJ(PIN)

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

5. When several inputs are submitted to a current injection, the maximum ∑IINJ(PIN) is the absolute sum of the

positive and negative injected currents (instantaneous values).
