Product specification
Double multiprotocol IC card interface
TDA8007B
Supply
The circuit operates within a supply voltage range of
2.7 to 6 V. The supply pins are V
DD
, V
DDA
, GND and
AGND. Pins V
DDA
and AGND supply the analog drivers to
the cards and have to be externally decoupled because of
the large current spikes that the cards and the step-up
converter can create. Pins V
DD
and GND supply the rest of
the chip. An integrated spike killer ensures that the
contacts to the cards remain inactive during power-up or
power-down. An internal voltage reference is generated
which is used within the step-up converter, the voltage
supervisor and the V
CC
generators.
The voltage supervisor generates an alarm pulse, whose
length is defined by an external capacitor tied to pin
DELAY, when V
DD
is too low to ensure proper operation
(1 ms per 1 nF typical).
This pulse may be used as a reset pulse by the system
microcontroller (pin RSTOUT, active HIGH). It is also used
inordertoeitherblockanyspuriousnoiseoncardcontacts
during the microcontrollers reset, or to force an automatic
deactivation of the contacts in the event of supply dropout
(see Sections “Activation sequence” and “Deactivation
sequence”).
After Power-on, or after a voltage drop, bit SUPL is set
within the Hardware Status Register (HSR) and remains
set until HSR is read-out outside the alarm pulse. Pin INT
is LOW for the duration that RSTOUT is active.
If needed, a complete reset of the chip may be performed
by discharging the capacitor C
DELAY
.
