on a card insertion / removal to allow power saving modes. Card insertion / removal is generated from
the respective card switch detection inputs (whose polarity is programmable).
The built-in ICC Interface has a linear regulator (V
cards in accordance with the ISO 7816-3 and EMV4.1 standards. This converter uses the V
nominal) input supply source. See the power supply management section above for more detail.
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 external smart card interface, they need to be handled manually through the USR GPIO
pins. The external 73S8010x devices directly connect the I/O (SIO) and clock (SCLK) signals and control
is handled via the I
Figure 15 shows how multiple 8010 devices can be connected to the 73S1210F.
