TDA8007BHL Multiprotocol IC card interface Rev. 9.1 18 June 2012 Product data sheet 1. General description The TDA8007BHL 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, EMV4.2 and EMV 2000. It is addressed on a non-multiplexed 8-bit databus, by means of address registers AD0, AD1, AD2 and AD3. TDA8007BHL/C3 can be also addressed through a multiplexed access. 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 V to 6 V. TDA8007BHL/C4 supports only non multiplex access and TDA8007BHL/C3 support both non multiplexed and multiplexed access. 2. Features and benefits Control and communication through an 8-bit parallel interface, compatible with non-multiplexed memory access, TDA8007BHL/C3 can be also addressed through a 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 5 %, 65 mA (max.) 3 V 8 %, 50 mA (max.) or 1.8 V 10 %, 30 mA (max.) with controlled rise and fall times Dual cards clock generation (up to 10 MHz), with three times synchronous frequency 1 1 1 doubling (f , f , f and f ) XTAL 2 XTAL 4 XTAL 8 XTAL 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 EMV4.2 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:TDA8007BHL NXP Semiconductors Multiprotocol IC card interface in Protocol T = 0: 11.8 ETU in Protocol T = 1: 10.8 ETU 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 V to 6 V), doubler, tripler or follower according to V and V CC DD 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 (except C4x, C8x): 6 kV (min.) Software library for easy integration within the application Power-down mode for reducing current consumption when no activity. 3. Applications Multiple smart card readers for multiprocessor applications (EMV banking, digital pay TV and access control, etc.). 4. Quick reference data Table 1.
