TDA8034HN
Smart card interface
[1]
I = input, O = output, I/O = input/output, G = ground and P = power supply.
[2]
If pin PRESN is LOW, the card is considered to be present. During card insertion, debouncing can occur on these signals. To counter
this, the TDA8034HN has a built-in debouncing timer (typically 8 ms).

Uses an internal 11 k
pull-up resistor connected to pin V
CC.
[4]
Uses an internal 20 k
pull-up resistor connected to pin V
DD(INTF).

Functional description
Remark: Throughout this document the ISO 7816 terminology conventions have been
adhered to and it is assumed that the reader is familiar with these.
8.1 Power supplies
The power supply voltage ranges are as follows:
VDDP: 4.85 V to 5.5 V when VCC_SEL2 is HIGH (VCC = 5 V)
VDDP: 3 V to 5.5 V when VCC_SEL2 is LOW (VCC = 3 V) or when VCC_SEL1 is LOW
(VCC = 1.8 V)
VDD: 2.7 V to 3.6 V
All interface signals to the system controller are referenced to VDD(INTF). All card contacts
remain inactive during power up or power down. After powering up the device, pin OFFN
remains LOW until pin CMDVCCN is set HIGH and pin PRESN is LOW. During power
down, pin OFFN goes LOW when VDDP falls below the falling threshold voltage (Vth).
The internal oscillator frequency (fosc(int)) is only used during the activation sequences.
When the card is not activated (pin CMDVCCN is HIGH), the internal oscillator is in low
frequency mode to reduce power consumption.
This device has a Low Drop-Off (LDO) voltage regulator connected to pin VCC, and is
used instead of a DC-to-DC converter. It ensures a minimum VCC of 4.75 V and that the
power supply voltage on pin VDDP does not fall below 4.85 V when pin VCC_SEL2 is
HIGH, for a maximum load current of 65 mA.
