1. Maximum electrical ratings are defined as those values beyond which damage to the device may occur at TA = +25°C.
2. This current represents the maximum peak current the pin can sustain, not the NCN6000 consumption (see Ibatop).
3. Human Body Model, R = 1500 , C = 100 pF.
4. Absolute Maximum Rating beyond which damage to the device may occur
DescriptionThe NCN6000 is an integrated circuit dedicated to the smart card interface applications. The NCN6000 handles any type of smart card through a simple and flexible microcontroller interface. On top of that,thanks to the builtin chip select pin, several couplers can be connected in parallel. The NCN6000 is particularly suited for low cost,low power applications, with high extended battery life coming from extremely low quiescent current.
