To utilize the Android Open Accessories, FTDI has released the FT311D. This is a hard-coded USB Android Host IC dedicated to accessing the AOA mode on Android platforms. This IC allows designers to bridge an interface on their peripheral hardware to an Android tablet or smart-phone platform over the Android USB device port. The FT311D will enumerate the Android platform and provide an interface via GPIO, UART, PWM, I2C Master, SPI Slave, or SPI Master between a customer’s Android platform and their peripheral hardware. Simply select the interface mode with pull up/pull down resistors on the FT311D mode select pins and plug into an Android (3.1 or later) platform to access peripheral hardware over USB via Androids’ Open Accessory Mode. The FT311D system allows providers to enhance connectivity to the mobile ecosystem with the ability to create applications that capitalize on the Android platform’s resources such as high-performance processing, accelerometers, and touch-screen interfaces.
