73 / 467 page  DocID14587 Rev 14 73/467 RM0016 Power supply 104 7 Power supply The MCU has four distinct power supplies: • VDD/VSS: Main power supply (3 V to 5.5 V) • VDDIO/VSSIO: I/O power supply (3 V to 5.5 V) • VDDA/VSSA: Power supply for the analog functions • VREF+/VREF-: Reference supply for Analog Digital Converter The VDD/VSS pins are used to supply the internal Main Voltage Regulator (MVR) and the internal Low Power Voltage Regulator (LPVR). The 2 regulator outputs are connected and provide the 1.8 V supply (V18) to the MCU core (CPU, Flash and RAM) In low power modes the system automatically switches from the MVR to the LPVR in order to reduce current consumption. To stabilize the MVR, a capacitor must be connected to the VCAP pin (for more details refer to the datasheet electrical characteristics section). Depending on the package size, there are one or two pairs of dedicated pins for VDDIO/VSSIO to supply power to the I/Os. VDDA/VSSA and VREF+/VREF- are connected to the Analog to Digital Converter (ADC). Figure 17. Power supply overview |
