3. This formula has to be applied only on the power supplies related to the IO structure described in the pin

definition table.

4. To sustain a voltage higher than 4 V the internal pull-up/pull-down resistors must be disabled.

5. Include VREF- pin.

∑IVDD

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

1. All main power (VDD, VDDA, 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)

150

IVDD(PIN)

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

100

IVSS(PIN)

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

100

IIO(PIN)

Output current sunk by any I/O and control pin except FT_f

Output current sunk by any FT_f pin

Output current 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.

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

IINJ(PIN)(3)

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

lower than the specified maximum value.

Injected current on FT_xxx, TT_xx, NRST pins

-5/0(4)

4. A negative injection is induced by VIN < VSS. IINJ(PIN) must never be exceeded. Refer also to Table 14:

Voltage characteristics for the minimum allowed input voltage values.

∑|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).
