DESCRIPTION

· The TDA8024 is a cost-efficient analog interface for 3V or 5V smart cards, designed to manage supply, protection, and control functions between the card and microcontroller.

· It serves as a direct replacement for the TDA8004AT and requires minimal external components.

FEATURES

· Supports 3V or 5V IC card supply with protected bidirectional I/O lines.

· Includes a DC-to-DC converter for VCC generation, capable of handling current spikes up to 20 MHz.

· Features thermal and short-circuit protection, automatic activation/deactivation sequences, and enhanced ESD protection (>6 kV).

· Integrated 26 MHz crystal oscillator and clock generation for cards up to 20 MHz.

· ISO 7816, GSM11.11, and EMV compatibility.

APPLICATIONS

· Ideal for use in systems requiring a reliable interface for smart cards, particularly in payment systems and secure access applications.
