91 / 141 page ![]() DS9895 Rev 8 91/141 STM32F301x6 STM32F301x8 Electrical characteristics 115 Figure 24. I/O AC characteristics definition 1. See Table 55: I/O AC characteristics. 6.3.15 NRST pin characteristics The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up resistor, RPU (see Table 53). Unless otherwise specified, the parameters given in Table 56 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 23. MS34942V1 10% 90% 50% tr(IO)out External output on CL Maximum frequency is achieved if (tr + tf) ≤ 2/3)T and if the duty cycle is (45-55%) 10% 50% 90% when loaded by CL T tf(IO)out (see note 1).

Guaranteed by design. 2. The pull-up is designed with a true resistance in series with a switchable PMOS. This PMOS contribution to the series resistance must be minimum (~10% order) . |
