the respective card switch detection inputs (whose polarity is programmable).
The built-in ICC Interface has a low dropout regulator (V
CC
generator) capable of driving 1.8V, 3.0V and
5.0V smart cards in accordance with the ISO 7816-3 and EMV4.0 standards. This converter requires
separate 5.0V input supply source designated as VPC. Auxiliary I/O lines C4 and C8 are only provided
for the built-in interface. If support for the auxiliary lines is necessary for the externa
