SIM Card Controller

The ET4555 is a level shifter analog circuit designed to translate the voltages between a SIM Card and an external microcontroller or MPU. A built−in LDO−type DC−DC converter makes the ET4555 useable to drive 1.8 V & 3.0V SIM card. The device fulfills the ISO7816−3 smart card interface standard as w • Supports 1.8V or 3.0V Operating SIM Card\r\n• The LDO is able to Supply More than 50mA under 1.8V & 3.0V\r\n• Built−in Pullup Resistor for I/O Pin in Both Directions\r\n• All Pins are Fully ESD Protected According to ISO−7816 Specifications – ESD Protection on SIM Pins in Excess of 7 kV (Human Bod;
