2000 Nov 09 2 Philips Semiconductors Product specification Double multiprotocol IC card interface 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).
