Depending on the SDADCx operation mode, there can be more constraints between

VREFSD+, VDDSD12 and VDDSD3 which are described in reference manual RM0313.

VDDSD12 is the external power supply for PB2, PB10, and PE7 to PE15 I/O pins (the I/O pin ground is internally

connected to VSS). VDDSD3 is the external power supply for PB14 to PB15 and PD8 to PD15 I/O pins (the I/O pin ground

is internally connected to VSS). VDD (VDD_x) is the external power supply for all remaining I/O pins (the I/O pin ground is

internally connected to VSS).

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.

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

value.

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 19: Voltage characteristics for the maximum allowed input voltage values.

A positive injection is induced by VIN>VDDA while a negative injection is induced by VIN < VSS. IINJ(PIN) must never be

exceeded. Refer also to Table 19: Voltage characteristics for the maximum allowed input voltage values. Negative injection

disturbs the analog performance of the device. See note (2) below Table 62.

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

I

INJ(PIN) is the absolute sum of the positive and

negative injected currents (instantaneous values).
