IC card interface
TDA8002C
Logic circuitry
After power-up, the circuit has six possible states of
operation. Figure 9 shows the state diagram.
IDLE MODE
After reset, the circuit enters the idle mode. A minimum
number of functions in the circuit are active while waiting
for the microcontroller to start a session:
All card contacts are inactive
I/OUC, AUX1UC and AUX2UC are high-impedance
Oscillator (XTAL) runs, delivering CLKOUT
Voltage supervisor is active.
LOW-POWER MODE
When pin MODE goes LOW, the circuit enters the
low-power (sleep) mode. As long as pin MODE is LOW no
activation is possible.
If pin MODE goes LOW in the active mode, a normal
deactivation sequence is performed before entering the
low-power mode. When pin MODE goes HIGH, the circuit
enters the normal operating mode after a delay of at least
6 ms (96 cycles of CLKOUT). During this time the
CLKOUT remains at 16 kHz.
All card contacts are inactive
Oscillator (XTAL) does not operate
The VDD supervisor, ALARM output, card presence
detection and OFF output remain functional
Internal oscillator is slowed to 32 kHz, providing 16 kHz
on CLKOUT.
ACTIVE MODE
When the activation sequence is completed, the
TDA8002C will be in the active mode. Data is exchanged
between the card and the microcontroller via the I/O lines.
