集成电路芯片资料和参数

芯片型号:ft6188

功能特点

+ The ft6188 is a SIM card controller specifically designed for dual SIM card enabled mobile phones. It supports both 1.8V and 3.0V SIM cards with integrated LDOs and level shifters. A Serial Port Interface (SPI) is used to configure and control the both cards.

+ The ft6188 works as a SIM card switch to bring cards to operation in turns at specified intervals. The device adopts a break-before-make scheme, i.e., to break the connection with a card before getting connected with the other so as to avoid possible communication collision.

+ The ft6188 SPI control interface is designed to communicate with microprocessors or controllers, such as cell phone baseband chips. The three-wire interface provides easy access with the universal data communication standards and saves the GPIO pins. The ft6188 is available in QFN3X3-20L package.
