Activation and Deactivation
8.1
Activation Sequence (Synchronous Mode)
The 73S8023C smart card interface IC has an internal ~10 ms delay at power-on reset or on application
of VDD > VDDF
1.
CMDVCC is set low.
. No activation is allowed at this time.
CMDVCC (edge triggered) must then be set low to
activate the card.
The following steps list the activation sequence and the timing of the card control signals when the
system controller sets
CMDVCC low:
2.
Turn on VCC and I/O (AUX1, AUX2) to reception mode at the end of (tACT
3.
RST is a copy of
RSTIN and CLK is a copy of STROBE after (t
).
1).

8.2
Deactivation Sequence (Synchronous Mode)
Deactivation is initiated either by the system controller by setting the
CMDVCC high, or automatically in
the event of hardware faults. Hardware faults are over-current, overheating, VDD
1.
RST goes low at time t
fault and card extraction
during the session and are indicated to the system controller by the fall of
OFF.
The following steps list the deactivation sequence and the timing of the card control signals when the
system controller sets the
CMDVCC high or a fault condition sets OFF low:

2.
CLK stops low at time t

3.
I/O goes low at time t

V
. Out of reception mode.
CC is shut down at time t 4. After a delay t 5 (discharge of the V CC capacitor), VCC is low.
