... I = input output, I/O = input/output ground and P = power supply. [2] If pin PRESN is HIGH, the card is considered to be present. During card insertion, debouncing can occur on these signals. To counter this, the TDA8034T/TDA8034AT has a built-in debouncing timer (typically 4.5 ms). [3] Uses an internal 11 k pull-up resistor connected to pin V ...

... The active pull-up feature ensures fast LOW-to-HIGH transitions making the TDA8034T/TDA8034AT capable of delivering more than 1 mA output voltage of 0. load of 80 pF. At the end of the active pull-up pulse, the output voltage is CC dependent on the internal pull-up resistor value and load current ...

... NXP Semiconductors 8.5 Shutdown mode After a power-on reset, if pin CMDVCCN is HIGH, the circuit enters the Shutdown mode, ensuring only the minimum number of circuits are active while the TDA8034T/TDA8034AT waits for the microcontroller to start a session. • all card contacts are inactive. The impedance between the contacts and GND is approximately 200 . • ...

... OSCINT Fig 6. 8.7 Deactivation sequence When a session ends, the microcontroller sets pin CMDVCCN HIGH. The TDA8034T/TDA8034AT then executes an automatic deactivation sequence by counting the sequencer back to the inactive state (see 1. Pin RST is pulled LOW (t11). 2. The clock is stopped, pin CLK is LOW (t12). 3. Pin I/O is pulled LOW (t13). ...

... On card insertion or removal, bouncing can occur in the PRESN signal. This depends on the type of card presence switch in the connector (normally open or normally closed) and the mechanical characteristics of the switch. To correct for this, a debouncing feature is integrated in to the TDA8034T/TDA8034AT. This feature operates at a typical duration of 4 debouncing feature. ...
