Dual SIM Card Controller

GENERAL DESCRIPTION

TThe BCT4302B is a dual SIM card control chip optimized for GSM/EDGE/GPRS/3G handsets, It provides the power conversion and signal level translation needed for advanced cell phones to interface with 1.8V and 3V SIMs. The device meets all requirements for 1.8V and 3V SIMs and contains LDO regulators to power 1.8V or 3V SIM card from a 2.7V to 5.5V input. A serial port interface(SPI) is used to control dual SIM channel individually. The BCT4302B I/O voltage can support 1.65V to 5.5V.

The BCT4302B is available in 20-pin 3mm x 3mm QFN package. The operating temperature range is from -25°C to +85°C.
