TDA8026

Multiple smart card slot interface IC

 RST(n) signal lines with current limitation at 20 mA, controlled by an embedded

programmable clock pulse counter on asynchronous cards or by a register on

synchronous cards

 ISO 7816-3 and EMV 4.31 payment systems compatibility

 VDD(INTF) supply voltage supervisor ensures correct communication between

microcontroller and circuit; threshold internally fixed or set using an external resistor

bridge

 VDD supply voltage supervisor for spike suppression during power-on and emergency

deactivation at power-off; threshold internally fixed

 Card presence input with a 17.8 ms (typical) built-in debouncing system on card slots

1 and 2

 One interrupt signal (IRQN)

Applications

 Point Of Sale terminals

 Multiple SAM contact readers
