DESCRIPTION
CMDVCC
19

18
Command VCC (negative assertion): Logic low on this pin causes the LDO regulator to ramp
the VCC supply to the card and initiates a card activation sequence, if a card is present.
5V
/#V
3
20
31
5 volt / 3 volt card selection: Logic one selects 5 volts for VCC and card interface, logic low
selects 3 volt operation. When the part is to be used with a single card voltage, this pin should
be tied to either GND or VDD. However, it includes a high impedance pull-up resistor to default
this pin high (selection of 5V card) when not connected.
CLKSTOP
7
---
4
Stops the card clock signal during a card session when set high (card clock STOP mode).
Internal pull-down resistor allows this pin to be left as an open circuit if the clock STOP mode
is not used.
CLKLVL
8
---
5
Sets the logic level of the card clock STOP mode when the clock is de-activated by setting pin
7 high. Logic low selects card STOP low. Logic high selects card STOP high. Internal pull-
down resistor allows this pin to be left as an open circuit if the clock STOP mode is not used.
CLKDIV1

Sets the divide ratio from the XTAL oscillator (or external clock input) to the card clock. These
pins include pull-down resistors.

Interrupt signal to the processor. Active Low - Multi-function indicating fault conditions and
card presence. Open drain output configuration – It includes an internal 22k pull-up to VDD.
RSTIN

Reset Input: This signal is the reset command to the card.

System controller data I/O to/from the card. Includes a pull-up resistor to VDD.

System controller auxiliary data I/O to/from the card. Includes a pull-up resistor to VDD.
SYSTEM CONTROLLER INTERFACE
3 separated digital inputs allow direct control of the card interface from the host as follows:
Pin
CMDVCC: When low, starts an activation sequence
Pin RSTIN: controls the card Reset signal (when enabled by the sequencer)
Pin 5V/
#V: Defines the card voltage
Card clock is controlled by 4 digital inputs:
CLKDIV1 and CLKDIV2 define the division rate for the clock frequency, from the input
clock frequency (crystal or external clock)
CLKSTOP (active high) allows card power down mode by stopping the card clock
CLKLEV defines the card clock level of the card power down mode.
Interrupt output to the host: As long as the card is not activated, the
OFF pin informs the host about the card
presence only (Low = No card in the reader). When
CMDVCC is set low (Card activation sequence requested
from the host), low level on
OFF means a fault has been detected (e.g. card removal during card session, or
voltage fault, or thermal / over-current fault) that automatically initiates a deactivation sequence.
