NCN4555MNR2G

NCN4555MNR2G is a SIM card power supply and level shifter. It is a level shifter analogue circuit designed to translate the voltages between a SIM Card and an external microcontroller or MPU. The device fulfils the ISO7816−3 smart card interface standard as well as GSM 11.11 and related (11.12 and 11.18) and 3G mobile requirements (IMT−2000/3G UICC standard). With the STOP (active high) pin a low current shutdown mode can be activated making the battery life longer. The card power supply voltage (SIM-VCC) is selected using a single pin (MOD-VCC). Typical application includes SIM card interface circuit for 2G, 2.5G and 3G mobile phones, identification module, smart card readers, wireless PC cards.
