The definition and values of input/output AC characteristics are given in Figure 32 and Table 58 , respectively.

Unless otherwise specified, the parameters given in Table 58 are derived from tests performed under the ambient temperature and V DD supply voltage conditions summarized in Table 16 .

Table 58. I/O AC characteristics (1)(2) (continued)

Table 58. I/O AC characteristics (1)(2) (continued)

1. Guaranteed by design.
2. The I/O speed is configured using the OSPEEDRy[1:0] bits. Refer to the STM32F4xx reference manual for a description of the GPIOx_SPEEDR GPIO port output speed register.
3. The maximum frequency is defined in Figure 32 .
4. For maximum frequencies above 50 MHz and V DD > 2.4 V, the compensation cell should be used.

Stresses above the absolute maximum ratings listed in Table 13 , Table 14 , and Table 15 may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

Device mission profile (application conditions) is compliant with JEDEC JESD47 Qualification Standard, extended mission profiles are available on demand.

Table 13. Voltage characteristics

VIN maximum value must always be respected. Refer to

injected current.

Table 14

for the values of the maximum allowed

Table 14. Current characteristics

1. A positive injection is induced by V IN >V DDA while a negative injection is induced by V IN <V SS . IINJ(PIN) must never be exceeded. Refer to Table 13 for the maximum allowed input voltage value.

2. When several inputs are submitted to a current injection, the maximum Σ I INJ(PIN) is the absolute sum of the positive and negative injected currents (instantaneous values).

The maximum chip-junction temperature, T J max, in degrees Celsius, can be calculated using the following equation:

T J max = T A max + (P D max x JA )
