CLRC663 Quickstart Guide
3.5 Schematic description
The following parts describe the RC663 evaluation reader board schematic, the part list,
and the layout of the PCB completely in order to give the user the possibility to take the
evaluation reader as a reference design for contactless smartcard reader integration.
3.6 Interface section
3.6.1 Power supply
Fig 6. Power supply circuit
The power supply can be connected with a 2.5 mm dc plug. The polarity of the plug is
managed automatically on the PCB. The supplied voltage should be in a range of 7.5 V
to 12.0 V and can be unregulated. The power supply should be able to provide at least
250 mA.
The main supply voltage at TVDD and PVDD is 5 V.
The Core supply Voltage at AVDD and DVDD is 1.8 V.
After plugging the voltage supply, the LED on the PCB should light up.
