The is a multiple Smart Card Slot Interface IC for addressing multiple smart card slots in a Point Of Sales POS terminal. It can address up to two main cards synchronous or asynchronous smart cards supported and up to four security access modules SAMs. Its packaging supports the latest payment terminal security requirements. The VDD, VDDINTF supply voltages can be applied to the device at any time, in any sequence. All interface signals to the system controller are referenced to the VDDINTF supply voltage which can be lower or higher than VDD. The voltage supervisor can be used to perform power-on resets POR and supply drop detection during a card session. The supervisors control the internal regulated supply voltage VDDINTREGD and the microcontroller interface supply voltage VDDINTF to ensure problem-free operation of the TDA8026.
