I. Explanation of terms
(1) VCC: C=circuit means circuit, i.e. the voltage connected to the circuit
(2) VDD: D=device means device, that is, the internal working voltage of the device.
(3) VSS: S=series means common connection, usually refers to the voltage of the common ground terminal of the circuit
(4) VEE: negative voltage supply; source (S) of the field effect tube
(5) VBAT: When connected to the VBAT pin using a battery or other power source, the contents of the backup register can be saved and the RTC maintained when VDD is powered down. If no external battery is used in the application, the VBAT pin should be connected to the VDD pin.
(6) VPP: Programming/erase voltage.
(7) GND: Often designated as the voltage reference base in circuits.
(8) The difference between V and VA is: digital vs. analogue
Digital circuit supply VCC
Analogue circuit supply VCCA
VDD is the digital operating voltage, that is, the power supply into the chip
VDDA is the analogue voltage or analogue positive power supply, which is the power supply from the chip to the outside
The difference between CC and DD is: the difference between the supply voltage and the working voltage (usually VCC>VDD)
