FT311D
(USB Android Host IC)
The FT311D is a Full Speed USB host
specifically targeted at providing
access to peripheral hardware from an
Android platform with a USB device
port. The device will bridge the USB
port to six user selectable interface
types and has the following advanced
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.
7 GPIO lines interface option
Basic UART interface with RXD, TXD, RTS, CTS
pins option.
TX_ACTIVE signal for controlling transceivers
on RS485 interfaces.
4 PWM channels option.
I
2
C master interface option.
SPI Slave interface option supporting modes 0,
1, 2 and 3 with MSB/LSB options
SPI Master interface option supporting modes
0, 1, 2 and 3 with MSB/LSB options.
USB error indicator pin
Suitable for use on any Android platform
supporting Android Open Accessory Mode
(Typically
3.1
onwards,
however
some
platforms may port Open Accessory Mode to
version 2.3.4)
12MHz oscillator using external crystal.
Integrated power-on-reset circuit.
+3V3 Single Supply Operation with 5V tolerant
inputs.
USB 2.0 Full Speed compatible.
Extended operating temperature range; -40⁰C
to 85⁰C.
Available in compact Pb-free 32 Pin LQFP and
QFN packages (both RoHS compliant).
