Smart Card Interface  
Pin Description  
PIN  
NAME  
FUNCTION  
CLKDIV1, Clock Divider. Determines the divided-down input clock frequency (presented at XTAL1 or from a  
1, 2  
CLKDIV2  
crystal at XTAL1 and XTAL2) on the CLK output pin. Dividers of 1, 2, 4, and 8 are available.  
5V/3V Selection Pin. Allows selection of 5V or 3V for communication with an IC card. Logic-high selects  
5V operation; logic-low selects 3V operation. See Table 3 for a complete description of choosing card  
voltages.

PGND  
Analog Ground  
Step-Up Converter Contact. Charge-pump capacitor. Connect a 100nF capacitor (ESR < 100m)  
between CP1 and CP2.

V
Charge-Pump Supply. Must be equal to or higher than V . Connect a supply of at least 3.3V.  
DD  
DDA  
V
Charge-Pump Output. Connect a 100nF capacitor (ESR < 100m) between V and GND.  
UP  
UP  
Card Presence Indicator. Active-low card presence inputs. When the presence indicator becomes  
active, a debounce timeout begins. After 8ms (typ) the OFF signal becomes active.  
9
PRES  
Card Presence Indicator. Active-high card presence inputs. When the presence indicator becomes  
active, a debounce timeout begins. After 8ms (typ) the OFF signal becomes active.

PRES  
I/O  
Smart Card Data-Line Output. Card data communication line, contact C7.  
AUX2,  
AUX1  
Smart Card Auxiliary Line (C4, C8) Output. Data line connected to card reader contacts C4 (AUX1) and  
C8 (AUX2).  
12, 13

16  
CGND  
CLK  
Smart Card Ground  
Smart Card Clock. Card clock, contact C3.  
Smart Card Reset. Card reset output from contact C2.  
RST  
Smart Card Supply Voltage. Decouple to CGND (card ground) with 2 x 100nF or 100 + 220nF  
capacitors (ESR < 100m).

DD  
GND  
Digital Ground  
OFF  
Status Output. Active-low interrupt output to the host. Use a 20kintegrated pullup resistor to V  
.
DD  
XTAL1,  
XTAL2  
Crystal/Clock Input. Connect an input from an external clock to XTAL1 or connect a crystal across  
XTAL1 and XTAL2. For the low idle-mode current variant, an external clock must be driven on XTAL1.  
24, 25  
26  
I/OIN  
I/O Input. Host-to-interface chip data I/O line.  
AUX1IN,  
AUX2IN  
27, 28  
C4/C8 Input. Host-to-interface I/O line for auxiliary connections to C4 and C8.
