Multiprotocol IC Card coupler
TDA8006
Deactivation sequence
When the session has completed, the microcontroller sets
CMDVCC LOW (t10). The circuit then executes an
automatic deactivation sequence:
Card reset (RST goes LOW) (t11)
Clock is stopped (t12)
I/O goes LOW (t13)
VCC falls to 0 V with typically 0.16 V/s slew rate (t14)
The step-up converter is stopped and CLK, RST, VCC
and I/O become low impedance to GND (t15).
t11 =t10 + 164T, t12 =t11 + 12T, t13 =t11 +T,
t14 =t11 + 32T, t15 =t11 + 5T.
tde is the time that VCC requires to fall to less than 0.3 V.

Protection
The main hardware fault conditions monitored by the
circuit are:
Overcurrent on VCC
Short circuits between VCC and other contacts
Card take-off during transaction.
When one of these problems is detected, the security logic
block sets the OFF bit LOW which generates an interrupt
warning the microcontroller and initiates an automatic
deactivation of the contacts.
When the deactivation has completed and CMDVCC has
been set LOW, the OFF bit goes HIGH, unless the problem
was caused by a card extraction, in which case it remains
LOW until a card is inserted.
