The NCN6000DTBG is a compact integrated circuit designed for smart card interface applications, fully compliant with ISO7816-3 and EMV standards. It supports a wide battery supply voltage range from 2.7 V to 6.0 V and features a programmable CRD_VCC supply, accommodating both 3.0 V and 5.0 V card operations. The device includes a built-in DC-DC converter that requires only a single external inductor for efficient power conversion, enhancing battery life due to its low quiescent current. Key functionalities include full control of the power-up and power-down sequences, a programmable card clock generator, and built-in chip select logic for parallel coupling of multiple couplers. The NCN6000DTBG also offers robust ESD protection on card pins, fault monitoring capabilities, and programmable card detection. Typical applications include e-commerce interfaces, ATM smart cards, and pay TV systems, making it suitable for low-cost, low-power projects requiring reliable smart card communication.
