NCN4557: Dual SIM Card / Smart Card Interface
The NCN4557 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 NCN4557 useable to drive 1.8 V and 3.0 V SIM card. The device fulfills 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 TS 31.101).
特性
- Supports 1.8V or 3.0V Operating SIM Card
- The LDO is able to supply more than 50mA under 1.8V and 3.0V
- Built-in pullup resistor for I/O pin in both directions.
- All pins are fully ESD protected according to ISO-7816 Specifications - ESD Protection on SIM pins in excess of 7kV (Human Body Model)
- Supports more than 5MHz clock
应用
- SIM Card Interface Circuit for 2G, 2.5G and 3G
- Identification Modules
- Smart Card Readers
- Wireless PC Cards
