Hot-selling and scarce TDA8007BHL/C2 Double multiprotocol IC card interface QFP48 spot stock

Product Descriptions

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 anon-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 of2.7 to 6 V.

Product 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 V CC 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)
