Electrical characteristics

224

1. Applicable only for STM32F7x9 sales types.

2. All main power (VDD, VDDA, VDDSDMMC, VDDUSB, VDDDSI) and ground (VSS, VSSA) pins must always be

connected to the external power supply, in the permitted range.

3. VIN maximum value must always be respected. Refer to Table 15 for the values of the maximum allowed

injected current.

4. Include VREF- pin.

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

permitted range.

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.

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

exceeded. Refer to Table 14: Voltage characteristics for the values of the maximum allowed input voltage.

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).
