The 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 features include a 3 or 5V supply for the IC (VDD) and a separate 5V ±10% supply for the step-up converter (VDDP) used for VCC generation. It offers three protected half-duplex bidirectional buffered I/O lines (C4, C7, C8). The device includes VCC regulation with ±5% tolerance, requiring specific capacitor configurations. Thermal and short-circuit protections are present on all card contacts, along with automatic activation/deactivation sequences for enhanced reliability.
Operating within an ambient temperature range of -25°C to +85°C, the TDA8004T supports card clock frequencies up to 20 MHz. It is compatible with ISO 7816, GSM11.11, and EMV standards, making it suitable for applications in banking, electronic payment, identification, and Pay TV.
The TDA8004T is supplied in a SO28 package, designed for surface mount applications.
The TDA8004T has two supply rails: VDD operates from 2.7V to 6.5V, and VDDP (step-up supply) operates from 4.5V to 6.5V with a typical value of 5V.
The TDA8004T is available in an SO28 surface-mount package.
The TDA8004T operates over an ambient temperature range of -25°C to +85°C.
The card supply voltage (VCC) is regulated to 5V, with a DC range of 4.75V to 5.25V, and can deliver up to 65mA.
The TDA8004T supports a card clock frequency of up to 20 MHz.
