from an Android platform with a USB

device port. The FT311D IC will bridge the

USB port to any one of the six user

selectable interface types like GPIO, UART,

PWM, I2C Master, SPI Master, SPI Slave

and has the following advanced features:



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)



Based on single chip USB Android Host FT311D IC.

Entire USB protocol handled on the chip.

Any one of the six user selectable interface types:-

GPIO, UART, PWM, I2C Master, SPI Master, SPI Slave

Interface options selectable via 3 mode select pins.



12MHz external crystal.

Standard USB Host connector to connect

with Android USB Slave device.



7 GPIO lines interface option

USB error indicator pin



+5V Single Supply Operation.

USB 2.0 Full Speed compatible.

Basic UART interface with RXD, TXD, RTS, CTS,

TX_ACTIVE pins option.

Extended operating temperature range; -

40 to +85⁰C.



4 PWM channels option.

I²C Master interface option.



Board dimensions: 68.58mm x 55.38mm

x 14.00mm (L x W x H).

SPI Slave interface option supporting modes 0, 1, 2

and 3 with MSB/LSB options



Reduce development time.



SPI Master interface option supporting modes 0, 1, 2

and 3 with MSB/LSB options.

Rapid integration into existing systems.

3 Function Description

The FT311D Development Module is intended for use as a hardware platform to enable easy evaluation of

FTDI’s FT311D Android Open Accessory USB Host controller. The FT311D Development Module includes

all the necessary components required by a user to begin developing Android Open Accessory

applications based on the FT311D device. The FT311D Development Module behaves like a bridge

between an Android device and the various I/O available. Selection of various modes is performed using

CONFIG[2:0] pins as shown in the Table 4.2.

3.1 Key Features

Easy to use Android Open Accessory Module translating the USB Device port of the android tablet into

any one of the six selectable interfaces like GPIO, UART, PWM, I²C Master, SPI Slave or SPI Master.



Selection of interface mode using jumpers JP1, JP2 and JP3

USB Type-A connector CN1 for connecting to Android USB slave peripherals.

IO port connectors CON1 / J3 and J4 used for the interface signals based on the

selected interface mode.

3.2 Functional Block Descriptions

The following paragraphs describe each function within the FT311D Development Module. Please refer to

the block diagram shown in Error! Reference source not found.Error! Reference source not found.Error!

Reference source not found..

Interface Mode Selection

Interface Mode selection is done using CONFIG[2:0] pins. Refer to chapter 4 for the details.

USB Host

USB Host port at CN1 is used for connecting the Android Open Accessory device. The USB host port does

not support other USB device classes.

Interface Signals

The interface signals at CON1 are based on the mode selected by the Interface Mode Selection.

Programming Port

The Programming Port at J7 is used for re-programming the FT311D device with new ROM file.

(NOTE: This is unlikely to be required as the module is delivered ready to use).
