Unit

∑IVDD

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

1. All main power (VDD, VDDA, VDDIO2, and VBAT) and ground (VSS, VSSA) pins must always be connected to

the external power supplies, in the permitted range.

∑IVSS

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(PIN)

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

∑IIO(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

LQFP packages.

140

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

IINJ(PIN)(3)(4)

3. Positive injection (when VIN > VDDIOx) is not possible on these I/Os, and does not occur for input voltages

lower than the specified maximum value.

4. A negative injection is induced by VIN < VSS. IINJ(PIN) must never be exceeded. Refer to Table 16 for the

minimum allowed input voltage values.

Injected current on FT_xxx, TT_xx, NRST pins

-5 / 0

∑|IINJ(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 negative injected currents (instantaneous values).
