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.
