The OM13485UL is the demo board for the NVT4556UK device with I²C control. The NVT4556 device is built for interfacing a SIM card with a single low-voltage host-side interface. The NVT4556 contains an LDO that can deliver two different voltages, 1.8 V or 3 V, from a typical mobile phone battery voltage, and three level translators to convert the data, RSTn and CLKn signals between a SIM card and a host microcontroller.
