Electrical characteristics

6.2

Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 9: Voltage characteristics,

Table 10: Current characteristics, and Table 11: Thermal characteristics 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.

External main supply voltage

(including VDDA and VDD)(1)

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. Negative injection disturbs the analog performance of the device. See note in Section 6.3.17.

Injected current on five-volt tolerant I/O(3) RST and B pins

3. Positive current injection is not possible on these I/Os. A negative injection is induced by VIN<VSS. IINJ(PIN)

must never be exceeded. Refer to Table 9 for maximum allowed input voltage values.

Injected current on any other pin(4)

4. 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 9: Voltage characteristics for the maximum allowed input voltage

values.

ΣIINJ(PIN)

Total injected current (sum of all I/O and control pins)(5)

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

ΣIINJ(PIN) is the absolute sum of the

positive and negative injected currents (instantaneous values).
