87 / 128 page  STM32F37x Electrical characteristics Doc ID 022691 Rev 3 87/128 Figure 21. I/O AC characteristics definition 6.3.15 NRST characteristics NRST pin characteristics The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up resistor, RPU (see Table 52). Unless otherwise specified, the parameters given in Table 55 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 22. ai14131 10% 90% 50% tr(IO)out OUTPUT EXT ERNAL ON 50pF Maximum fr equency is achieved if (tr + tf) 2/3)T and if the duty cycle is (45-55%) 10% 50% 90% when loaded by 50pF T tr(IO)out Table 55.
