Notes:

1. Data based on characterization results, not tested in production.

2. When the current limitation is not possible, the VIN maximum must be respected, otherwise refer to IINJ(PIN) specifica-

tion. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. Refer to Section 13.2.2

on page 123 for more details.

3. Configuration not recommended, all unused pins must be kept at a fixed voltage: using the output mode of the I/O for

example or an external pull-up or pull-down resistor (see Figure 82). Data based on design simulation and/or technology

characteristics, not tested in production.

4. The RPU pull-up equivalent resistor is based on a resistive transistor (corresponding IPU current characteristics de-

scribed in Figure 83).

5. To generate an external interrupt, a minimum pulse width has to be applied on an I/O port pin configured as an external

interrupt source.
