Pin Description
PIN
NAME
FUNCTION
1, 2
CLKDIV1,
CLKDIV2
Clock Divider. Determines the divided-down input clock frequency (presented at XTAL1 or from a
crystal at XTAL1 and XTAL2) on the CLK_ output pin. Dividers of 1, 2, 4, and 8 are available.
3
5V/3V
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. The 1_8V pin overrides the setting on this pin if
active. See Table 3 for a complete description of choosing card voltages.
4
1_8V
1.8V Operation Selection. This active-high input puts the device into 1.8V smart card communication
mode. The selected interface (when activated) powers a card with a 1.8V supply and all I/O lines
operate at 1.8V.
5
VCCB
Smart Card Supply Voltage, Interface B. Decouple to CGND (card ground) with 2 x 100nF or 100 +
200nF capacitors (ESR < 100m ).
6
VDDA
Smart Card Interface Supply. 5V power supply for powering the card interface.
7
RSTB
Smart Card Reset, Interface B. Card reset output from contact C2.
8
CLKB
Smart Card Clock, Interface B. Card clock, contact C3.
9, 14
CGND
Smart Card Ground
10
PRESA
Interface A Card Presence Indicator. Active-high card presence input for the first card interface.
When the presence indicator becomes active, a debounce timeout begins. After 8ms (typ), the OFF
signal becomes active if the first card interface is selected (SEL_AB low), else the OFF2 signal
becomes active.
11
I/OA
Smart Card Data-Line Output, Interface A. Card data communication line, contact C7. This pin is
only active if the first card interface is selected (SEL_AB low) and the interface has gone through an
activation sequence.
