Multiprotocol smart card interface TDA8007B

FEATURES

• 8-bit parallel interface for control and communication,
compatible with multiplexed or non-multiplexed
memory access

• Specific ISO UART with parallel access on I/O for
automatic convention processing, variable baud rate
through frequency or division ratio programming, error
management at character level for T = 0, extra guard
time register

• 1 to 8 characters FIFO in reception mode

• Parity error counter in reception mode

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

65 mA (max.) with controlled rise and fall times)

• Dual smart card clock generation (up to 10 MHz), with
two times synchronous frequency doubling

• Cards clock STOP HIGH, clock STOP LOW or

1.25 MHz (from internal oscillator) for cards
power-down mode

• Automatic activation and deactivation sequence
through an independent sequencer

• Supports asynchronous protocols T = 0 and T = 1, in
accordance with ISO 7816 and EMV

• Versatile 24-bit timeout counter for ATR (Answer To
Reset) and waiting times processing

• 22 ETU counter for Block Guard Time

• Supports synchronous cards

• Short-circuit current limitations

• Special circuit for killing spikes during power-on/-off

• Supply supervisor for power-on/-off reset

• Step-up converter (supply voltage from 2.5 to 6 V),

doubler, tripler or follower according to VCC and V

• Additional I/O pin, allowing use of the ISO UART for
another analog interface (I/OAUX)

• Additional interrupt pin, allowing detection of level
toggling on an external signal (INTAUX)

DD

• Fastandefficientswappingbetweencard 1,card 2and
athird card whose I/O is tiedto IOAUX, 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 side (6 kV min.)

• Software library for easy integration within the

application

• Power-down mode, reducing current consumption
during periods of non-activity.

APPLICATIONS

• Multiple smart card readers for multiprotocol
applications (EMV banking, Digital pay TV, Access
control etc.).

GENERAL DESCRIPTION

The TDA8007B is a low cost card interface for dual smart
card readers. Controlled through a parallel bus, it takes
care of all ISO 7816, EMV and GSM11-11 requirements.
Itmay be interfaced to the P0/P2ports of an 80C51 family
microcontroller, and be addressed as a memory through
MOVX instructions. It may also be addressed on a
non-multiplexed 8-bit data bus, by means of register
addresses AD0, AD1, AD2 and AD3. The integrated ISO
UART and the timeout counters allow easy use, even at
high baud rates with no real time constraints. Due to its
chip select and external I/O and INT features, it greatly
simplifies the realization of any number of types of card
readers. It gives the cards and the mode a very high level
ofsecurity,due to its special hardware against ESD, short
circuits, power failure, etc. Its integrated step-up
converter allows operation within a supply voltage range
of 2.5 to 6 V.

A software library has been developed, taking care of all
actions required for T = 0, T = 1 and synchronous
protocols, see Application Reports.
