Pin Description (continued)
PIN
NAME
FUNCTION
12
I/OB
Smart Card Data-Line Output, Interface B. Card data communication line, contact C7. This pin is
only active if the second card interface is selected (SEL_AB high) and the interface has gone
through an activation sequence.
13
PRESB
Interface B Card Presence Indicator. Active-high card presence input for the second card interface.
When the presence indicator becomes active, a debounce timeout begins. After 8ms (typ), the OFF
signal becomes active if the second card interface is selected (SEL_AB high), else the OFF2 signal
becomes active.
15
CLKA
Smart Card Clock, Interface A. Card clock, contact C3.
16
RSTA
Smart Card Reset, Interface A. Card reset output from contact C2.
17
VCCA
Smart Card Supply Voltage, Interface A. Decouple to CGND (card ground) with 2 x 100nF or 100 +
220nF capacitors (ESR < 100m ).
18
VDDA2
Smart Card Interface Supply. 5V power supply for powering the card interface. While this pin is not
required to be connected to 5V (it can be left not connected (N.C.)), it is recommended for the best
performance when delivering power to a 5V smart card.
19
CMDVCC
Activation Sequence Initiate. Active-low input from host.
20
RSTIN
Card Reset Input. Reset input from the host.
21
VDD
Supply Voltage
22
GND
Digital Ground
23
OFF
Status Output for Selected Interface. Active-low interrupt output to the host. Includes a 20k
integrated pullup resistor to VDD. This pin reflects fault events and PRES_ events on the currently
selected interface only (behaving as if it were a DS8024 with only one interface). The OFF2 pin
should be used to monitor presence events on the nonselected interface.
24, 25
XTAL1,
XTAL2
Crystal/Clock Input. Connect an input from an external clock to XTAL1 or connect a crystal across
XTAL1 and XTAL2.
26
I/OIN
I/O Input. Host-to-interface chip data I/O line.
27
OFF2
Status Output for Nonselected Interface. This pin passes through the presence signal for the
nonselected interface. If SEL_AB is low (the A interface is selected), this pin reflects the state of the
PRESB input. If SEL_AB is high (the B interface is selected), this pin reflects the state of the PRESA
input.
28
SEL_AB
Interface Selection. This pin selects the interface the input pins (I/OIN, RSTIN, etc.) communicate
with and control. If SEL_AB is low, the A interface is selected. Activation sequences power up VCCA
and communication occurs with CLKA, I/OA, and RSTA. If SEL_AB is high, the B interface is
selected. Both interfaces can be powered and clocking at the same time. See the Switching A/B
Interfaces section for more information.
