1. The maximum frequency is defined with (Tr+ Tf) ≤ 2/3 T, and Duty cycle comprised between 45 and 55%.

2. The fall and rise time are defined, respectively, between 90 and 10%, and between 10 and 90% of the

output waveform.

3. This value represents the I/O capability but the maximum system frequency is limited to 64 MHz.

NRST pin characteristics

The NRST pin input driver uses the CMOS technology. It is connected to a permanent 

pull-up resistor, RPU.

Unless otherwise specified, the parameters given in the table below are derived from tests

performed under the ambient temperature and supply voltage conditions summarized in

Table 24: General operating conditions.
