POWER DOWN SEQUENCE
The NCN6001 provides an automatic Power Down
sequence, according to the ISO7816-3 specifications, and
the communication session terminates immediately. The
sequence is launched when the card is extracted, or when the
CRD_VCC voltage is overloaded as described by the
ISO/CEI 7816-3 sequence depicted hereafter:
ISO7816-3 sequence:
Force RST to Low
Force CLK to Low, unless it is already in this state
Force C4 & C8 to Low
Force CRD_IO to Low
Shut Off the CRD_VCC supply
Since the internal digital filter is activated for any card
insertion or extraction, the physical power sequence will be
activated 50 s (typical) after the card has been extracted. Of
course, such a delay does not exist when the MPU
intentionally launches the power down. Figure 6 shows the
oscillogram captured in the NCN6001 demo board.
The internal active pull down NMOS connected across
CRD_VCC and GND discharges the external reservoir
capacitor in 100 s (typical), assuming Cout = 10 F.
