60 / 92 page ![]() Electrical characteristics STM32F103x8, STM32F103xB 60/92 Doc ID 13587 Rev 11 Figure 24. I/O AC characteristics definition 5.3.13 NRST pin characteristics The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up resistor, RPU (see Table 34). Unless otherwise specified, the parameters given in Table 37 are derived from tests performed under the ambient temperature and VDD supply voltage conditions summarized in Table 9. 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 37. NRST pin characteristics Symbol Parameter Conditions Min Typ Max Unit VIL(NRST) (1) 1. Guaranteed by design, not tested in production.
