General Description
The MT6306 is a SIM card / GPIO control chip optimized for GSM handsets, especially those based on
the MediaTek MT62xx system solution. It supports up to four SIM interfaces or 12 GPIOs plus six GPIs.
Each SIM interface can be individually programmed as GPIOs. The SIM interface supports both 1.8V and
3V SIM cards. An I2C interface is used to control SIM channel individually.
The MT6306 is available in 28-pin 4mm x 4mm QFN package. The operating temperature range is from
-25
°
C to +85
°
C.
