DESCRIPTION/ORDERING INFORMATION

The TXS02326A is a complete dual-supply standby Smart Identity Module (SIM) card solution for interfacing

wireless baseband processors with two individual SIM subscriber cards to store data for mobile handset

applications. It is a custom device which is used to extend a single SIM/UICC interface to support two

SIMs/UICCs.

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;

two low-dropout (LDO) voltage regulators with output voltages that are selectable between 2.95-V Class-B and

1.8-V Class-C interfaces; an integrated "fast-mode" 400 kb/s "slave" I²C control register interface, for

configuration purposes; and a 32-kHz clock input, for internal timing generation. The TXS02326A also includes a

shutdown input and a comparator input that detects battery pack removal to safely power-down the two SIM

cards. The shutdown input and comparator input are equipped with two programmable debounce counter (i.e.

BSI input and SDN input) circuits realized by an 8 bit counter.

The voltage-level translator has two supply voltage pins. VDDIO sets the reference for the baseband interface

and can be operated from 1.7-V to 3.3-V. VSIM1 and VSIM2 are programmed to either 1.8-V or 2.95-V, each

supplied by an independent internal LDO regulator. The integrated LDO accepts input battery voltages from 2.3-

V to 5.5-V and outputs up to 50 mA to the B-side circuitry and external Class-B or Class-C SIM card.
