Description

Symbol

CRD_IO_A
INPUT/OUTPUT
This pin carries the data serial connection between the external smart card #A and
the microcontroller. A built-in bidirectional level shifter is used to adapt the card and
the MCU, regardless of the power supply voltage of each signals.
This pin is biased by a pull up resistor connected to CRD_VCC_A. When CS = High,
the CRD_IO_A holds the previous I/O logic state and resume to a normal operation
when this pin is reactivated.
The pin is hardwired to zero, the bias being provided by the V
CC
supply, when either
the V
CC
voltage drops below 2.7 V, or during the CRD_VCC_A start-up time.
25
PWR_GND
POWER
This pin carries the power current flow coming from the built in DC/DC converters. It
is associated with the external card # A. It must be connected to the system Ground
and care must be observed at PCB layout level to avoid the risk of spike voltages on
the logic lines.
26
L2_A
POWER
Connects one side of the external DC/DC converter inductor #A (Note 1)
27
L1_A
POWER
Connects one side of the external DC/DC converter inductor #A (Note 1).
28
PWR_VCC_A
POWER
This pin is connected to the positive external power supply. The device sustains any
voltage from +2.7 V to +5.5 V. This voltage supplies the NCN6004A internal circuits
and is regulated by the internal DC/DC converter to provide the DC voltage to the
external card. A high quality capacitor must be connected across pin 28 and
PWR_GND, 10 F/6.0 V ceramic X7R or X5R type is recommended.
Note: The voltage present at pin 28 and 33 must be equal to the voltage present at
pin 42.
29
CRD_VCC_A
POWER
This pin provides the power supply to the external smart card #A. The V
CC
voltage is
defined by programming the NCN6004A accordingly. Since the cards have indepen-
dent DC/DC converter, the output voltage can have any value independently from
CARD_B.
A high quality, low ESR capacitor is mandatory to achieve the V
specifications.
Using two 4.7 F/6.0 V ceramic X7R or X5R capacitors in parallel is recommended.
30
CRD_CLK_A
OUTPUT
This pin is connected to the CLK external smart card #A pin. The signal comes from
the built-in frequency divider dedicated to the #A card. The clock is selected and con-
trolled by setting the logic inputs according to Table 1. The slope of the output clock can
be selected between one of the two programmable mode: SLOW or FAST (Table 8).
The pin is hardwired to zero, the bias being provided by the V
supply, when either
the V
CC
voltage drops below 2.7 V, or during the CRD_VCC_A start-up time.
31
CRD_CLK_B
OUTPUT
This pin is connected to the CLK external smart card #B pin. The signal comes from
the built-in frequency divider dedicated to the #B card. The clock is selected and con-
trolled by setting the logic inputs according to Table 1. The slope of the output clock can
be selected between one of the two programmable mode: SLOW or FAST (Table 8).
The pin is hardwired to zero, the bias being provided by the V
CC
supply, when either
the V
CC
voltage drops below 2.7 V, or during the CRD_VCC_B start-up time.
32
CRD_VCC_B
POWER
This pin provides the power supply to the external smart card #B. The V
CC
voltage is
defined by programming the NCN6004A accordingly. Since the cards have indepen-
dent DC/DC converter, the output voltage can have any value independently from
CARD_A.
A high quality, low ESR capacitor is mandatory to achieve the V
CC
specifications.
Using two 4.7 F/6.0 V ceramic X7R or X5R capacitors in parallel is recommended.
33
PWR_VCC_B
POWER
This pin is connected to the positive external power supply. The device sustains any
voltage from +2.7 V to +6.0 V. This voltage supplies the NCN6004A internal circuits
and is regulated by the internal DC/DC converter to provide the DC voltage to the
external card. A high quality capacitor must be connected across pin 33 and
PWR_GND, 10 F/6.0 V ceramic X7R type is recommended.
Note: The voltage present on pin 28 and 33 must be equal to the voltage present on
pin 42
34
L2b
POWER
Connects one side of the external DC/DC converter inductor #B (Note 1).
35
L1b
POWER
Connects one side of the external DC/DC converter inductor #B (Note 1).
36
PWR_GND

is associated with the external card # B. It must be connected to the system Ground
