TDA8004T Description

Short technical summary and product information.

The Philips TDA8004T is a low-cost analog interface for asynchronous smart cards, designed to be placed between the card and a microcontroller. It provides essential supply protection and control functions with minimal external components.

Key electrical specifications include a VDD supply voltage range of 2.7 to 6.5 V and a VDDP step-up supply voltage of 4.5 to 6.5 V. The device supports a card clock frequency up to 20 MHz and features integrated thermal and short-circuit protections on all card contacts. It also includes enhanced ESD protection on the card side, exceeding 6 kV.

Applications for the TDA8004T include IC card readers for banking, electronic payment systems, identification, and Pay TV. The component is housed in a 28-lead SO28 plastic small outline package, suitable for surface mount applications.

Additional features include automatic activation and deactivation sequences, a supply supervisor for power-on/off spike management, and a 26 MHz integrated crystal oscillator. The device is compatible with ISO 7816, GSM11.11, and EMV standards.
