... Ctb POWER 14 SIM_VCC POWER NCN6010 Description This pin is connected to the system controller power supply suitable to operate from a 3.6 V typical battery. A low ESR ceramic capacitor (4.7 mF typical) shall be used to bypass the power supply voltage. A Low level on this pin resets the SIM interface, switching off the SIM_VCC, according to the ISO7816-3 Power Down procedure (See Table 1 and Figure 3) ...

... Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. Maximum electrical ratings are defined as those values beyond which damage to the device may occur at T NCN6010 Symbol V DD SIM_VCC -0 ...
