Supply
The circuit operates within a supply voltage range of
4.2 to 6 V. The supply pins are VDD, VDDA, GND, AGND,
VDDRAM and GNDRAM. Pins VDDA and AGND supply the
card analog drivers and have to be externally decoupled
because of the large current spikes that the card and the
step-up converter can create. VDDRAM and GNDRAM
supply the auxiliary RAM and should be decoupled
separately. VDD and GND supply the rest of the chip.
An integrated spike killer ensures the contacts to the card
remain inactive during power-up or power-down.
An internally generated voltage reference is used by the
step-up converter, the voltage supervisor and the VCC
generator.
If VDD is too low to ensure proper operation, the voltage
supervisor generates an alarm pulse, whose length is
defined by an external capacitor tied to the CDELAY pin,
(1 ms per 1 nF typical). This pulse is used to reset the
controller and is used in parallel with an external reset
input which can come from the system controller. It is also
used to either block any spurious on-card contacts during
a controller reset or to force an automatic deactivation of
the contacts in the event of supply drop-out (see
Sections “Activation sequence” and “Deactivation
sequence”). It is also fed to an external open-drain output
(called ALARM) which can be chosen active HIGH or LOW
by mask option (see Table 12).
Step-up converter
Except for the VCC generator and the other card contact
buffers, the whole circuit is powered by VDD, VDDA and
VDDRAM. If the supply voltage is 4.2 V, then a higher
voltage is needed for the supply to the ISO contacts. When
a card session is requested by the controller, the
sequencer first starts the step-up converter. This uses
switched capacitors which are clocked at a frequency of
approximately 2.5 MHz by an internal oscillator.
The output voltage VUP is regulated at approximately 6 V
and then fed to the VCC generator. VCC and GND are used
as a reference for all other card contacts.
