96 / 231 page  Electrical characteristics STM32F427xx STM32F429xx 96/231 DocID024030 Rev 6 6.3.2 VCAP1/VCAP2 external capacitor Stabilization for the main regulator is achieved by connecting an external capacitor CEXT to the VCAP1/VCAP2 pins. CEXT is specified in Table 19. Figure 24. External capacitor CEXT 1. Legend: ESR is the equivalent series resistance. 6.3.3 Operating conditions at power-up / power-down (regulator ON) Subject to general operating conditions for TA. Table 20. Operating conditions at power-up / power-down (regulator ON) 6.3.4 Operating conditions at power-up / power-down (regulator OFF) Subject to general operating conditions for TA. Table 19. VCAP1/VCAP2 operating conditions(1) 1. When bypassing the voltage regulator, the two 2.2 µF VCAP capacitors are not required and should be replaced by two 100 nF decoupling capacitors. Symbol Parameter Conditions CEXT Capacitance of external capacitor 2.2 µF ESR ESR of external capacitor < 2 Ω Symbol Parameter Min Max Unit tVDD VDD rise time rate 20 ∞ µs/V VDD fall time rate 20 ∞ Table 21. Operating conditions at power-up / power-down (regulator OFF)(1) 1. To reset the internal logic at power-down, a reset must be applied on pin PA0 when VDD reach below 1.08 V. Symbol Parameter Conditions Min Max Unit tVDD VDD rise time rate Power-up 20 ∞ µs/V VDD fall time rate Power-down 20 ∞ tVCAP VCAP_1 and VCAP_2 rise time rate Power-up 20 ∞ VCAP_1 and VCAP_2 fall time rate Power-down 20 ∞ |
