I/O port characteristics

General input/output characteristics

Unless otherwise specified, the parameters given in Table 65 are derived from tests

performed under the conditions summarized in Table 20: General operating conditions. All

I/Os are designed as CMOS- and TTL-compliant.

I/O pin capacitance

1. Tested in production.

2. Guaranteed by design, not tested in production.

3. Represents the pad leakage of the I/O itself. The total product pad leakage is given by



ITotal_Ileak_max = 10 μA + number of I/Os where VIN is applied on the pad x Ilkg(Max).

4. Max(VDDXXX) is the maximum value among all the I/O supplies.

5. VIN must be lower than [Max(VDDXXX) + 3.6 V].

6. Refer to Figure 20: I/O input characteristics.
