79 / 185 page  DocID022152 Rev 4 79/185 STM32F405xx, STM32F407xx Electrical characteristics 5.3.2 VCAP_1/VCAP_2 external capacitor Stabilization for the main regulator is achieved by connecting an external capacitor CEXT to the VCAP_1/VCAP_2 pins. CEXT is specified in Table 16. Table 15. Limitations depending on the operating power supply range Operating power supply range ADC operation Maximum Flash memory access frequency with no wait state (fFlashmax) Maximum Flash memory access frequency with wait states(1) (2) I/O operation Clock output Frequency on I/O pins Possible Flash memory operations VDD =1.8 to 2.1 V(3) Conversion time up to 1.2 Msps 20 MHz(4) 160 MHz with 7 wait states – Degraded speed performance – No I/O compensation up to 30 MHz 8-bit erase and program operations only VDD = 2.1 to 2.4 V Conversion time up to 1.2 Msps 22 MHz 168 MHz with 7 wait states – Degraded speed performance – No I/O compensation up to 30 MHz 16-bit erase and program operations VDD = 2.4 to 2.7 V Conversion time up to 2.4 Msps 24 MHz 168 MHz with 6 wait states – Degraded speed performance –I/O compensation works up to 48 MHz 16-bit erase and program operations VDD = 2.7 to 3.6 V(5) Conversion time up to 2.4 Msps 30 MHz 168 MHz with 5 wait states – Full-speed operation –I/O compensation works –up to 60 MHz when VDD = 3.0 to 3.6 V –up to 48 MHz when VDD = 2.7 to 3.0 V 32-bit erase and program operations 1. It applies only when code executed from Flash memory access, when code executed from RAM, no wait state is required. 2. Thanks to the ART accelerator and the 128-bit Flash memory, the number of wait states given here does not impact the execution speed from Flash memory since the ART accelerator allows to achieve a performance equivalent to 0 wait state program execution. 3. VDD/VDDA minimum value of 1.7 V is obtained when the device operates in reduced temperature range, and with the use of an external power supply supervisor (refer to Section : Internal reset OFF). 4. Prefetch is not available. Refer to AN3430 application note for details on how to adjust performance and power. 5. The voltage range for OTG USB FS can drop down to 2.7 V. However it is degraded between 2.7 and 3 V. |
