Figure 17 shows how multiple 73S8010x devices can be connected to the 73S1217F.
The built-in ICC Interface has a linear regulator (V
cards in accordance with the ISO 7816-3 and EMV4.0 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
