The definitions and values of the input and output AC characteristics are given in the following figure and table, respectively.

Unless otherwise stated, the parameters listed in the following table are provided under the ambient temperature and supply voltage in accordance with the condition Table 5-3.

Table 5-23 I/O AC characteristics (1)(2)(3)

1. The speed of the I/O port can be configured through MODEx[1:0]. Refer to the description of the GPIO port configuration register in this chip user manual.
2. The maximum frequency is defined in Figure 5-8.
3. Guaranteed by design, not tested in production.

Figure 5-8 I/O AC characteristics

Stresses above the absolute maximum ratings given in "Absolute Group Maximum Ratings" list (Table 5-1, Table 5-2 and Table 5-3) 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.

Table 5-1 Voltage characteristics

1. All power (VDD, VDDA) and ground (VSS, VSSA) pins must always be connected to the external power supply system within the permitted range.
2. The maximum value of VIN must be respected. Refer to the table below for the maximum allowed injected current values.
3. All main power (VDD, VDDA) and ground (VSS, VSSA) pins must always be connected to an external power supply in the permitted range.
4. This current consumption must be correctly distributed to all I/O and control pins. The total output current must not be sunk/sourced between two consecutive power supply pins referring to high pin count LQFP package.
5. The reverse injection current can interfere with the analog performance of the device.
6. When VIN > VDDA, a positive injected current is generated; when VIN < VSS, a reverse injected current is generated. Do not exceed IINJ(PIN).
7. When there is simultaneous injection current for multiple inputs, the maximum value of ΣIINJ(PIN) is equal to the sum of the absolute values of the forward injection current and the reverse injection current (instantaneous value) .
