143 / 361 page  DS12117 Rev 8 143/360 STM32H753xI Electrical characteristics (rev Y) 318 6.3.16 NRST pin characteristics The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up resistor, RPU (see Table 59: I/O static characteristics). Unless otherwise specified, the parameters given in Table 64 are derived from tests performed under the ambient temperature and VDD supply voltage conditions summarized in Table 23: General operating conditions. Figure 22. Recommended NRST pin protection 1. The reset network protects the device against parasitic resets. 2. The user must ensure that the level on the NRST pin can go below the VIL(NRST) max level specified in Table 59. Otherwise the reset is not taken into account by the device. Table 64. NRST pin characteristics Symbol Parameter Conditions Min Typ Max Unit RPU(2) Weak pull-up equivalent resistor(1) 1. 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) . VIN = VSS 30 40 50 ㏀ VF(NRST)(2) 2. Guaranteed by design.
