Description

General part information

TXS4555 Series

The TXS4555 is a complete Smart Identity Module (SIM) card solution for interfacing wireless baseband processors with a SIM card to store I/O for mobile handset applications. The device complies with ISO/IEC Smart-Card Interface requirements as well as GSM and 3G mobile standards. It includes a high-speed level translator capable of supporting Class-B (2.95 V) and Class-C (1.8 V) interfaces, a low-dropout (LDO) voltage regulator that has output voltages that are selectable between 2.95-V Class-B and 1.8-V Class-C interfaces.

Note: The Exposed center thermal pad must be connected to Ground

The device has two supply voltage pins. VCC can be operated over the full range of 1.65 V to 3.3 V and VBATTfrom 2.3 to 5.5 V. VPWR is set to either 1.8 V or 2.95 V and is supplied by an internal LDO. The integrated LDO accepts input voltages as high as 5.5 V and outputs either 1.8 V or 2.95 V at 50 mA to the B-side circuitry and to the external SIM card. The TXS4555 enables system designers to easily interface low-voltage microprocessors to SIM cards operating at 1.8 V or 2.95 V.
