FTDI FT311D USB Android Host ICs

FTDI FT311D / FT312D USB Android Host ICs

FTDI's FT311D and FT312D USB Android Host ICs are Full Speed USB hosts specifically targeted at providing access to peripheral hardware from an Android platform with a USB device port. FT311D will bridge the USB port to six user selectable interface types and has advanced features that include single chip USB to selectable interface, entire USB protocol  handled on the chip, interface selectable via 3 mode select pins, basic UART interface with RXD, TXD, RTS, CTS pins, 4 PWM channels, I2C master interface, SPI slave or master interface option supporting modes 0, 1, 2 and 3 with MSB/LSB, and USB error indicator pin. FT312D features a UART interface for peripheral integration. See below for development modules.

FT311D Features
  • Single chip USB to selectable interface
  • Entire USB protocol handled on the chip. No USB specific firmware programming required.
  • Interface options selectable via 3 mode select pins
