207 / 361 page ![]() DS12117 Rev 8 207/360 STM32H753xI Electrical characteristics (rev V) 318 7.1.6 Power supply scheme Figure 67. Power supply scheme 1. N corresponds to the number of VDD pins available on the package. 2. A tolerance of +/- 20% is acceptable on decoupling capacitors. Caution: Each power supply pair (VDD/VSS, VDDA/VSSA ...) must be decoupled with filtering ceramic capacitors as shown above. These capacitors must be placed as close as possible to, or below, the appropriate pins on the underside of the PCB to ensure good operation of the MSv46116V5 BKUP IOs VDD domain Analog domain Core domain (VCORE) Backup domain D3 domain (System logic, EXTI, Peripherals, RAM) D1 domain (CPU, peripherals, RAM) OPAMP, Comparator Voltage regulator ADC, DAC Flash D2 domain (peripherals, RAM) Power switch VCAP VSS VDDLDO VBAT VDDA VREF+ VREF- VSSA Backup regulator VDD Backup RAM Power switch HSI, LSI, CSI, HSI48, HSE, PLLs IOs USB regulator VDD50USB VDD33USB VSS VSS VSS REF_BUF VSS IO logic VREF+ USB IOs VSS VSW LSE, RTC, Wakeup logic, backup registers, Reset IO logic VBKP VBAT charging VREF- VDDA VBAT 1.2 to 3.6V VDD VDDLDO VREF VDD33USB VDD50USB 1μF |
