TDA8024 Datasheet PDF (Standard smart card interface)

TDA8024 - Standard smart card interface

Description

The TDA8024 is a complete and cost-efficient analog interface for asynchronous 3 V 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.

Features

IC card interface.
3 V 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-to-DC converter for VCC generation separately powered from a 5 V  20% supply (VDDP and PGND).
3 V or 5 V  5% regulated card supply voltage (VCC) with appropriate decoupling has the following capabilities:.
ICC < 80 mA at VDDP = 4 V to 6.5 V.
Handles current spikes of 40 nAs up to 20 MHz.

TDA8024 Standard smart card interface Rev. 4.0 — 3 June 2016 Product data sheet 1. General description The TDA8024 is a complete and cost-efficient analog interface for asynchronous 3 V 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 NXP internet site (www.nxp.com) and from “Application note AN10141”. CAUTION This device is sensitive to ElectroStatic Discharge (ESD). Observe precautions for handling electrostatic sensitive devices. Such precautions are described in the ANSI/ESD S20.20, IEC/ST 61340-5, JESD625-A or equivalent standards. 2.
