55 / 81 page ![]() STM8L101xx Electrical parameters Doc ID 15275 Rev 11 55/81 NRST pin The NRST pin input driver is CMOS. A permanent pull-up is present. RPU(NRST) has the same value as RPU (see Table 26 on page 50). Subject to general operating conditions for VDD and TA unless otherwise specified. Figure 30. Typical NRST pull-up resistance RPU vs. VDD Table 30. NRST pin characteristics Symbol Parameter Conditions Min Typ (1) Max Unit VIL(NRST) NRST input low level voltage (1) 1. Data based on characterization results, not tested in production.
