General description

The TDA8007BHL/C is a cost-effective card interface for dual smart card readers. Controlled through a parallel bus, it meets all requirements of:

  • ISO 7816, GSM 11-11 and EMV 3.1.1
    (TDA8007BHL/C2 and TDA8007BHL/C3)
  • ISO 7816, GSM 11-11 and EMV 2000
    (TDA8007BHL/C3).

It may be interfaced to the ports P0, P1 and P2 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, external input/output and interrupt features, it greatly simplifies the realization of a reader of any number of cards. 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. The integrated step-up converter allows operation within a supply voltage range of 2.7 to 6 V; it may be supplied with a voltage higher than the IC?s supply.

A software library has been developed that covers all actions required for T = 0 and T = 1 and synchronous protocols (see application note ?AN01054?).

Features

  • Control and communication through an 8-bit parallel interface, compatible with multiplexed or non-multiplexed memory access
  • Specific ISO UART with parallel access input/output for automatic convention processing, variable baud rate through frequency or division ratio programming, error management at character level for T = 0 and extra guard time register
  • FIFO for 1 to 8 characters in reception mode
  • Parity error counter in reception mode and in transmission mode with automatic re-transmission
  • Dual VCC generation: 5 V +- 5pct, 65 mA (max.); 3 V+-8pct, 50 mA (max.) or 1.8 V +- 10pct, 30 mA (max.); with controlled rise and fall times
  • Dual cards clock generation (up to 10 MHz), with three times synchronous frequency doubling (fXTAL , 1/2 fXTAL , 1/4 fXTAL and 1/8 fXTAL )
  • Cards clock stop (at HIGH or LOW level) 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 3.1.1 (TDA8007BHL/C2 and TDA8007BHL/C3)
    • ISO 7816 and EMV 2000 (TDA8007BHL/C3)
  • Versatile 24-bit time-out counter for Answer To Reset (ATR) and waiting times processing
  • Specific Elementary Time Unit (ETU) counter for Block Guard Time (BGT): 22 in T = 1 and 16 in T = 0
  • Minimum delay between two characters in reception mode:
    • in Protocol T = 0:
      12 ETU (TDA8007BHL/C2)
      11.8 ETU (TDA8007BHL/C3)
    • in Protocol T = 1:
      11 ETU (TDA8007BHL/C2)
      10.8 ETU (TDA8007BHL/C3)
  • Supports synchronous cards
  • Current limitations in the event of short-circuit (pins I/O1, I/O2, VCC1 , VCC2 , RST1 and RST2)
  • Special circuitry for killing spikes during power-on/power-off
  • Supply supervisor for power-on/power-off reset
  • Step-up converter (supply voltage from 2.7 to 6 V), doubler, tripler or follower according to VCC and VDD
  • Additional input/output 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 three 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.
