*IC card interface


*General description

The TDA8024 is a complete and cost-efficient analog interface for asynchronous 3 or 5 V smart cards. It can be placed between the card and the microcontroller to perform all supply, protection and control functions. Very few external components are required. The TDA8024AT is a direct replacement for the TDA8004AT.

More information can be obtained from the Philips Internet site (http://www.semiconductors.philips.com) and from ?Application note AN10141?.


*Features

  • IC card interface
  • 3 or 5 V supply for the IC (VDD and GND)
  • Three specifically protected half-duplex bidirectional buffered I/O lines to card contacts C4, C7 and C8
  • DC/DC converter for VCC generation separately powered from a 5 V +- 20 pct supply (VDDP and PGND)
  • 3 or 5 V +- 5 pct regulated card supply voltage ((VCC) with appropriate decoupling has the following capabilities:
    • ICC < 80 mA at VDDP = 4 to 6.5 V
    • Handles current spikes of 40 nAs up to 20 MHz
    • Controls rise and fall times
    • Filtered overload detection at approximately 120 mA
  • Thermal and short-circuit protection on all card contacts
  • Automatic activation and deactivation sequences; initiated by software or by hardware in the event of a short-circuit, card take-off, overheating, VDD or VDDP drop-out
  • Enhanced ESD protection on card side (>6 kV)
  • 26 MHz integrated crystal oscillator
  • Clock generation for cards up to 20 MHz (divided by 1, 2, 4 or 8 through CLKDIV1 and CLKDIV2 signals) with synchronous frequency changes
  • Non-inverted control of RST via pin RSTIN
  • ISO 7816, GSM11.11 and EMV (payment systems) compatibility
  • Supply supervisor for spike-killing during power-on and power-off and Power-on reset (threshold fixed internally or externally by a resistor bridge); not for TDA8024AT
  • Built-in debounce on card presence contacts
  • One multiplexed status signal OFF.

Overseas Delivery Service

1. The Company provides the service in accordance with the overseas delivery procedure of the products whose trade contract is already signed through the overseas delivery network that has business connection with the Company. Overseas delivery is divided into as follows:
1) A domestic delivery phase: until the buyer’s product is delivered to a logistics center of a third party in business cooperation with the Company
2) An overseas delivery phase: until the product is delivered to the recipient through the overseas delivery network
2. For overseas delivery, the buyer’s order may be cancelled depending on the status of the delivery request. Return requested due to change of mind during delivery is limited to the phase of domestic delivery. Once the product has completed the domestic delivery phase and entered the overseas delivery phase, a return is not permitted unless the Company approves return or exchange due to an original defect in the delivered product.
3. A buyer requesting the Company’s approval on return or exchange must approve the original product defect or other grounds for return or exchange by submitting to the Company objective evidence. The costs and expenses for the delivery in connection with the return or exchange shall be paid by the Company once objective evidence has been approved.
4. The buyer who has received an approval to return or exchange of the product from the Company shall contact the DJmall customer center before the return of the product, including documents to verify costs and expenses for the delivery.
5. If the estimated cost of the delivery paid at purchase is greater than the actual delivery cost, the difference will be refunded to the buyer.
6. If the estimated cost of the delivery paid at purchase is less than the actual delivery cost, the buyer must make an additional payment to complete the delivery. If the difference is not paid within 3 months despite of continuous notice, the product may become the Company’s own property.
7. In the event of using overseas delivery service, the recipient is liable for all customs, taxes, duties and other cost imposes by the country to which the delivery is made.
