Description
Card Interface
I/O
22
IO
Card I/O: Data signal to/from smart card. Includes
an 11kΩ pull -up resistor to V CC
Will be tri-stated when SC/ USB is set low.
AUX1
21
IO
AUX1: Auxiliary data signal to/from smart card for
synchronous smart card operation. Smart card USB
DP signal for IS0-7816-12 USB smart card operation.
Includes an 11kΩ pull -up resistor to V CC for
synchronous / asynchronous operation only.
AUX2
20
IO
AUX2: Auxiliary data signal to/from smart card for
synchronous smart card operation. Smart card USB
DM signal for IS0-7816-12 USB smart card
operation. Includes an 11kΩ pull -up resistor to V CC
for synchronous / asynchronous operation only.
RST
18
O
Card reset: provides reset (RST) signal to card. RST
is the pass through signal on RSTIN. Internal control
logic will hold RST low when card is not activated or
VCC is too low. Will be tri-stated when SC/ USB is
set low.
