Double multiprotocol IC card interface
Product specification
TDA8007B
FEATURES
• Control and communication through an 8-bit parallel
interface, 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%, 65 mA (max.) or 3 V
±8%, 50 mA (max.) with controlled rise and fall times)
• Dual cards 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 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 Elementary Time Unit (ETU) counter for Block Guard
Time (BGT)
• Supports synchronous cards
• Current limitations in the event of short-circuit
• Special circuitry for killing spikes during power-on/-off
• Supply supervisor for power-on/-off reset
• Step-up converter (supply voltage from 2.7 to 6 V),
doubler, tripler or follower according to VCC and VDD
• Additional I/O pin allowing use of the ISO UART for
another analog interface (pin I/OAUX)
• 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 side [6 kV (min.)]
• Software library for easy integration within the
application
• Power-down mode for reducing current consumption
when no 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.
It may be interfaced to the P0/P2 ports of a 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 address
registers AD0, AD1, AD2 and AD3. The integrated ISO
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 INT features, it greatly
simplifies the realization of any number of cards readers.
It gives the cards and the reader a very high level of
security, due to its special hardware against ESD,
short-circuiting, power failure, etc. Its integrated step-up
converter allows operation within a supply voltage range of
2.7 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).
