FUNCTIONAL DESCRIPTION
Power supply
The supply pins for the chip are V
DGND1 and DGND2. V
DDA
and V
, V
DDA
DDD
, AGND,
DDD
(i.e. VDD) should be
in the range of 3.0 to 6.5 V. All card contacts remain
inactive during power-up or power-down.
On power-up, the logic is reset by an internal signal.
The sequencer is not activated until VDD reaches
V
th2+Vhys2
(see Fig.6). When VDD falls below V
th2
, an
automatic deactivation sequence of the contacts is
performed.
Chip selection
The chip select pin (CS) allows the use of several
TDA8002Cs in parallel.
When CS is HIGH, the pins RSTN, CMDVCC, MODE,
CV/TV, CLKDIV1, CLKDIV2, CLKSEL and STROBE
control the chip, pins I/OUC, AUX1UC and AUX2UC are
the copy of I/O, AUX1 and AUX2 when enabled (with
integrated 20 kΩ pull-up resistors connected to VDD) and
OFF is enabled.
When CS goes LOW, the levels on pins RSTIN,
CMDVCC, MODE, CV/TV, CLKDIV1, CLKDIV2 and
STROBE are internally latched, I/OUC, AUX1UC and
AUX2UC go to high-impedance with respect to I/O, AUX1
and AUX2 (with integrated 100 kΩ pull-up resistors
connected to VDD) and OFF is high-impedance.
Clock circuitry
The TDA8002C supports both synchronous and
asynchronouscards. There arethree methods to clockthe
circuitry:
• Apply a clock signal to pin STROBE
• Use of an internal RC oscillator
• Use of a quartz oscillator which should be connected
between pins XTAL1 and XTAL2 or an external clock
applied on XTAL1.
When CLKSEL is HIGH, the clock should be applied to the
STROBE pin. When CLKSEL is LOW, the internal
oscillators is used.
When an internal clock is used, the clock output is
availableon pin CLKOUT.The RC oscillator is selectedby
making CLKDIV1 HIGH and CLKDIV2 LOW. The clock
output to the card is available on pin CLK. The frequency
of the card clock can be the input frequency divided by
2 or 4, STOP low or 1.25 MHz, depending onthe states of
CLKDIV1 or CLKDIV2 (see Table 1).
When STROBE is used for entering the clock to a
synchronous card, STROBE should remain stable during
activation sequence otherwise the first pulse may be
omitted.
Do not change CLKSEL during activation. When in
low-power (sleep) mode, the internal oscillator frequency
which is available on pin CLKOUT is lowered to
approximately 16 kHz for power economy purposes.
Supply voltage supervisor (VDD)
This block surveys the V
supply. A defined retriggerable
DD
pulse of 10 ms minimum (tW) is delivered on the ALARM
output during power-up or power-down of VDD(see Fig.6).
This signal is also used for eliminating the spikes on card
contacts during power-up or power-down.
When VDD reaches V
th2+Vhys2
, an internal delay (tW) is
started. The ALARM output is active until this delay has
expired. When VDD falls below V
, ALARM is activated
th2
and a deactivation sequence of the contacts is performed.

I/O circuitry
The three I/O transceiversare identical. The state isHIGH
forall I/O pins (i.e. I/O,I/OUC, AUX1, AUX1UC, AUX2 and
AUX2UC). Pin I/O is referenced to VCC and pin I/OUC to
VDD, thus ensuring proper operation in the event that
VCC≠ VDD.
The first side on which a falling edge is detected becomes
a master (input). An anti-latch circuitry first disables the
detection of the falling edge on the other side, which
becomes slave (output), see Fig.8.
In the event of a conflict, both lines may remain LOW until
the software enables the lines to be HIGH. The anti-latch
circuitry ensures that the lines do not remain LOW if both
sides return HIGH, regardless of the prior conditions.
The maximum frequency on the lines is approximately
200 kHz.
When CS is HIGH, I/OUC, AUX1UC and AUX2UC are
internally pulled-up to VDD with 20 kΩ resistors. When
CS is LOW, I/OUC, AUX1UC and AUX2UC are
permanently HIGH (with integrated 100 kΩ pull-up
resistors connected to VDD).
After a delay time td (between 50 and 400 ns), the logic 0
present on the master sideis transferred on the slave side.

Logic circuitry
After power-up, the circuit has six possible states of
operation. Figure 9 shows the state diagram.
IDLE MODE
After reset, the circuit enters the idle mode. A minimum
number of functions in the circuit are active while waiting
for the microcontroller to start a session:
• All card contacts are inactive
• I/OUC, AUX1UC and AUX2UC are high-impedance
• Oscillator (XTAL) runs, delivering CLKOUT
• Voltage supervisor is active.
LOW-POWER MODE
When pin MODE goes LOW, the circuit enters the
low-power (sleep) mode. As long as pin MODE is LOW no
activation is possible.
If pin MODE goes LOW in the active mode, a normal
deactivation sequence is performed before entering the
low-power mode. When pin MODE goes HIGH, the circuit
enters the normal operating mode after a delay of at least
6 ms (96 cycles of CLKOUT). During this time the
CLKOUT remains at 16 kHz.
• All card contacts are inactive
• Oscillator (XTAL) does not operate
• The VDD supervisor, ALARM output, card presence
detection and OFF output remain functional
• Internal oscillator is slowed to 32 kHz, providing 16 kHz
on CLKOUT.
ACTIVE MODE
When the activation sequence is completed, the
TDA8002C will be in the active mode. Data is exchanged
between the card and the microcontroller via the I/O lines.

ACTIVATION SEQUENCE
From Idle mode, the circuit enters the activation mode
when the microcontroller sets the CMDVCC line LOW or
sets the MODE line HIGH when the CMDVCC line is
already LOW. The internal circuitry is then activated, the
internal clock is activated and an activation sequence is
executed. When RST is enabledit becomes the inverse of
RSTIN.

4. CLK is set by setting RSTIN to HIGH (t4)
5. RST is enabled (t5=t1+ 7T); after t5, RSTIN has no
further action on CLK, but is only controlling RST.
The value of VCC (5 or 3 V) must be selected by the level
on pin CV/TV before the activation sequence.

DEACTIVATION SEQUENCE
When a session is completed, the microcontroller sets the
CMDVCC line to HIGH state or MODE line to LOW state.
The circuit then executes an automatic deactivation
sequence by counting the sequencer down and thus end
in the Idle mode.

When one or more of these faults are detected, the circuit
pulls the interrupt line OFF to its active LOW state and a
deactivation sequence is initiated. In the event that the
card is present the interrupt line OFF is set to HIGH state
when the microcontroller has reset the CMDVCC line
HIGH (after completion of the deactivation sequence).
In the event that the card is not present OFF remains

SOLDERING
Introduction to soldering surface mount packages
Thistextgives a very brief insight toacomplextechnology.
A more in-depth account of soldering ICs can be found in
our
“Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
tothe printed-circuit board byscreenprinting, stencilling or
pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating,soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
Wave soldering
Conventional single wave soldering is not recommended
forsurfacemount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
The footprint must incorporate solder thieves at the
downstream end.
• Forpackageswith leads on four sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
During placement andbefore soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Manual soldering
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.

Suitability of surface mount IC packages for wave and reflow soldering methods
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
