Philips Electronics 

Philips Semiconductors

Dual multiprotocol smart card coupler

Objective specification

TDA8008

FEATURES

• 8xC51 core with 16 kbytes or EPROM (TDA8008),

256 bytes RAM, 512 bytes AUXRAM, Timer 0, 1, 2 and

enhanced UART

• Specific ISO 7816 UART, accessible with MOVX

instructions for automatic convention processing,

variable baud rate through frequency or division ratio

programming, error management at character level for

T = 0 protocol, extra guard time register

• Dual VCC generation (5 V ±5% or 3 V ±5%), maximum

current of 60 mA with controlled rise and fall times

• Dual cards clock generation (up to 10 MHz) with two

times synchronous frequency doubling

• Cards clock STOP HIGH or LOW or 1.25 MHz (from an

integrated oscillator) for cards power reduction mode

• Automatic activation and deactivation sequences

through an independent sequencer

• Supports the asynchronous protocols T = 0 and T = 1 in

accordance with ISO 7816 and EMV

• Versatile 24-bit time-out counter for Answer To Reset

(ATR) and waiting times processing

• 22 ETU counter for block guard time

• Supports synchronous cards

• Current limitations on cards contacts

• Special circuitry for killing spikes during power-on or off

• Supply supervisor for Power-on reset

• Step-up converter (supply voltage from 2.7 to 5.5 V at

16 MHz), doubler, tripler or follower according to VCC

and VDD

• Speed up to 25 MHz at VDD = 5 V

• Additional I/O pin allowing the use of the ISO 7816

UART for an external card interface (pin IOAUX)

• Additional interrupt pin allowing detection of level

toggling on an external signal (pin INTAUX)

• Fast and efficient swapping between the 3 cards due to

separate buffering of parameters for each card

• Chip select input allowing use of several devices in

parallel and memory space paging

• Enhanced ESD protections on card contacts (6 kV min.)

• Software library for easy integration within the

application

• Development tool with a TDA8007B and a regular

emulator.

APPLICATIONS

• Multiple smart card readers for multiprotocol

applications (EMV banking, digital pay TV, access

control, etc.).

GENERAL DESCRIPTION

The TDA8008 is a complete, one-chip, low cost dual smart

card coupler.

It can be used as the kernel of a multiple card reader. It can

handle all ISO 7816, EMV and GSM11-11 requirements.

The integrated ISO 7816 UART and the time-out counters

allow easy use even at high baud rates with no real time

constraints. Due to its chip select and external I/O and

interrupt features, it simplifies the realization of any

number of cards reader. It gives the cards and the set a

very high level of security, due to its special hardware

against ESD, short-circuiting, power failure and

overheating. Its integrated step-up converter allows

operation within a supply voltage range of 2.7 to 5.5 V at

16 MHz.

The OTP version of the TDA8008 allows fast and reliable

software development and fast product introduction.

A software library has been developed, that can handle all

actions required for T = 0, T = 1 and synchronous

protocols.
