Figure 61.
RESET pin protection when LVD is enabled
1.
When the LVD is enabled, it is recommended not to connect a pull-up resistor or capacitor. A 10nF pull-
down capacitor is required to filter noise on the reset line.
2.
When using the LVD:
- Check that all recommendations related to ICCCLK and reset circuit have been applied (see caution in
Table 2 and text above)
- Check that the power supply is properly decoupled (100nF + 10F close to the MCU). Refer to AN1709
and AN2017. If this cannot be done, it is recommended to put a 100nF + 1M
Ω pull-down on the RESET
pin.
- The capacitors connected on the RESET pin and also the power supply are key to avoid any startup
marginality. In most cases, steps 1 and 2 above are sufficient for a robust solution. Otherwise: replace
10nF pull-down on the RESET pin with a 5F to 20F capacitor.”
3.
In case a capacitive power supply is used, it is recommended to connect a 1M
Ω pull-down resistor to the
RESET pin to discharge any residual voltage induced by the capacitive effect of the power supply (this will
add 5A to the power consumption of the MCU).
