NCN4555
1.8V / 3V SIM Card Power
Supply and Level Shifter
The NCN4555 is a level shifter analog circuit designed to translate
the voltages between a SIM Card and an external microcontroller or
MPU. A built鈭抜n LDO鈭抰ype DC鈭扗C converter makes the NCN4555
useable to drive 1.8 V and 3.0 V SIM card. The device fulfills the
ISO7816鈭? smart card interface standard as well as GSM 11.11 and
related (11.12 and 11.18) and 3G mobile requirements (IMT鈭?000/3G
TS 31.101). With the STOP pin a low current shutdown mode can be
activated making the battery life longer. The Card power supply
voltage (SIM_V
CC
) is selected using a single pin (MOD_V
CC
).
