Type Description
Card Interface
I/O 25 15 IO Card I/O: Data signal to/from card. Includes a pull-up
resistor to V
CC.
AUX1 24 NA IO AUX1: Auxiliary data signal to/from card. Includes a pull-up
resistor to V
CC.
AUX2 23 NA IO AUX2: Auxiliary data signal to/from card. Includes a pull-up
resistor to V
CC.
RST 21 13 O Card reset: provides reset signal to card.
CLK 19 11 O Card clock: provides clock signal to card. The rate of this
clock is determined by the external clock frequency
provided on pin CLKIN.
PRES 26 16 I Card Presence switch: active high indicates card is present.
Should be tied to GND when not used, but includes a high-
impedance pull-down current source.
PRES 16 10 I Card Presence switch: active low indicates card is present.
Should be tied to VDD when not used, but includes a high-
impedance pull-up current source.
VCC 22 14 PSO Card power supply logically controlled by the sequencer,
output of LDO regulator. Requires an external filter
capacitor to GND.
GND 20 NA GND Card ground.
Miscellaneous Inputs and Outputs
CLKIN 11 5 I Clock source for the card clock.
TEST1 2 19 This pin must be tied to GND in typical applications.
TEST2 14 8 This pin must be tied to GND in typical applications.
NC 3,17,18 NA Non-connected pin.
Power Supply and Ground
VDD 28 17 System interface supply voltage and supply voltage for
internal circuitry.
VPC 15 9 LDO regulator power supply source.
GND 27 12 GND Ground.
Microcontroller Interface
CS 1 18 I When CS = 1, the control and signal pins are configured
normally. When CS is set low, CMDVCC%, RSTIN, and
CMDVCC# are latched, IOUC, AUX1UC, and AUX2UC are
set to high-impedance pull-up mode and do not pass data
to or from the smart card. Signals RDY and OFF are
disabled to prevent a low output and the internal pull-up
resistors are disconnected.
OFF 4 20 O Interrupt signal to the processor. Active low, multi-function
indicating fault conditions and card presence. Open drain
output configuration. It includes an internal 20 pull-up to
VDD. The pull-up is disabled in PWRDN and CS=0 modes.
