Description
The FXLP4555 is a level-shifter analog circuit designed
to translate the voltages between a SIM card and an
external baseband. A built-in LDO-type DC-DC
converter allows the FXLP4555 to drive 1.8V and 3.0V
SIM cards. The device fulfills the ISO7816-3 smart-card
interface standard as well as GSM 11.11 (11.12 and
11.18) and 3G mobile requirements (IMT-2000/3G UICC
standard). The EN pin enables a low-current Shutdown
Mode that extends battery life. The card power supply
voltage (VCC_C) is selected using a single pin (VSEL).
