8.4 Step up converter

Except for the V

for the ISO contacts supply. When a card session is requested by the microcontroller, the
sequencer first enables the step-up converter (a switched capacitors type) which is
clocked by an internal oscillator at a frequency of approximately 2.5 MHz.

The recognition of the supply voltage is done by the TDA8007BHL/C4 at approximately

reference for all other card contacts.
The correct sequence during activation and deactivation of the cards is ensured by two
specific sequencers, the clock is defined by a division ratio of the internal oscillator.
Activation (bit START = 1 in registers PCR1 or PCR2) is only possible if the card is
present (pin PRES is active high with an internal current source to ground) and if the
supply voltage is correct (voltage supervisor not active).
The presence of the cards is signalled to the microcontroller by register HSR. Bits PR1
or PR2 in register MSR are set if card 1 or 2 is present. Bits PRL1 or PRL2 are set if
pins PRES1 or PRES2 have been toggled.
During a session, the sequencer performs an automatic emergency deactivation on one
card in the event of card take-off, or short-circuit. Both cards are automatically deactivated
in the event of a supply voltage drop, or overheating. Register HSR is updated and the
INT line falls so that the system microcontroller is aware of what happened.
