The ET6304 is a dual SIM card control chip optimized for GSM handsets. It supports both 1.8V and 3V SIM cards. A serial
port interface (I2C) is used to control dual SIM channel individually. The ET6304 has an integrated detection of SIM card
presence function, including battery detection and contact detection in a directly user accessible card slots. If the SIM card
is pulled out, ET6304 can immediately and automatically shutdown the corresponding SIM card interface. When the SIM
card is inserted, ET6304 can immediately notify the baseband chip to execute activation process.
The ET6304 is available in 20pin 3mm x 3mm QFN package. The operating temperature range is from 25°C to +85°C.
