TDA8002  
Supply supervisor for spikes elimination and emergency  
FEATURES  
deactivation.  
Single supply voltage interface (3.3 or 5 V environment)  
Low-power sleep mode  
APPLICATIONS  
Three specific protected half-duplex bidirectional  
IC card readers for:  
– GSM applications  
– banking  
buffered I/O lines  
VCC regulation (5 V ±5%, ICC <65 mA at VDD = 5 V, with  
controlled rise and fall times  
Thermal and short-circuit protections with current  
limitations  
– electronic payment  
– identification  
– Pay TV  
Automatic ISO 7816 activation and deactivation  
sequences  
– road tolling.  
Enhanced ESD protections on card side (>6 kV)  
Clock generation for the card up to 12 MHz with  
synchronous frequency changes  
GENERAL DESCRIPTION  
The TDA8002 is a complete low-power, analog interface  
for asynchronous and synchronous cards. It can be placed  
between the card and the microcontroller. It performs all  
supply, protection and control functions. It is directly  
compatible with ISO 7816, GSM11.11 and EMV  
specifications.  
Clock generation up to 20 MHz (auxiliary clock)  
Synchronous and asynchronous cards (memory and  
smart cards)  
ISO 7816, GSM11.11 compatibility and EMV (Europay,  
Mastercard, Visa) compliant  
Step-up converter for VCC generation
