131 / 200 page ![]() DocID028800 Rev 1 131/200 STM32L431xx Electrical characteristics 168 Figure 29. 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 62: NRST pin characteristics. Otherwise the reset will not be taken into account by the device. 3. The external capacitor on NRST must be placed as close as possible to the device. 6.3.16 Analog switches booster Table 63. Analog switches booster characteristics(1) 1. Guaranteed by design. Symbol Parameter Min Typ Max Unit VDD Supply voltage 1.62 - 3.6 V tSU(BOOST) Booster startup time - - 240 µs IDD(BOOST) Booster consumption for 1.62 V ≤ VDD ≤ 2.0 V -- 250 µA Booster consumption for 2.0 V ≤ VDD ≤ 2.7 V -- 500 Booster consumption for 2.7 V ≤ VDD ≤ 3.6 V -- 900 |
