Philips Semiconductors Product specification IC card interface 8.3 TDA8024 The crystal oscillator runs as soon as the IC is powered up. If the crystal oscillator is used, or if the clock pulse on pin XTAL1 is permanent, the clock pulse is applied to the card as shown in the activation sequences shown in Figs 7 and 8. Clock circuitry The card clock signal (CLK) is derived from a clock signal input to pin XTAL1 or from a crystal operating at up to 26 MHz connected between pins XTAL1 and XTAL2.

Philips Semiconductors Product specification IC card interface 8.7 TDA8024 Active mode 1. RST goes LOW (t10). 2. CLK is held LOW (t12 = t10 + 0.5 × T) where T is 64 times the period of the internal oscillator (approximately 25 µs). When the activation sequence is completed, the TDA8024 will be in its active mode. Data is exchanged between the card and the microcontroller via the I/O lines.
Philips Semiconductors Product specification IC card interface 8.9 TDA8024 VCC generator There are two different cases (see Fig.10): • CMDVCC HIGH outside a card session. Output OFF is LOW if a card is not in the card reader, and HIGH if a card is in the reader. A voltage drop on the VDD supply is detected by the supply supervisor, this generates an internal Power-on reset pulse but does not act upon OFF. No short-circuit or overheating is detected because the card is not powered-up.

Philips Semiconductors Product specification IC card interface TDA8024 Notes 1. All parameters remain within limits but are tested only statistically for the temperature range. When a parameter is specified as a function of VDD or VCC it means their actual value at the moment of measurement. 2. If no external bridge is used then, to avoid any disturbance, it is recommended to connect pin 18 to ground. Pin 18 is not connected in the TDA8024AT 3.
