1.1 About the Interface Tile
The Interface Tile provides buffers and connectors that you can use with interface
devices implemented in the FPGA of a Versatile Logic Tile. The following devices or
interface connectors are present on the Interface Tile:
• eight-channel 12 bit ADC operating at up to 200kHz
• four-channel 12 bit DAC operating at up to 125kHz
• two CAN bus drivers
• USB host and OTG transceivers
• two I2C interfaces
• camera interface
• two stepper-motor interfaces
• RS232 transceiver
• IDE interface
• clock buffers
• JTAG interface
• 513-pin prototyping area with 272 I/O pins.
Figure 1-1 shows an example configuration that uses an Interface Tile.

1.2 Precautions
This section contains safety information and advice on how to avoid damage to the
Interface Tile.
1.2.1 Ensuring safety
The tile is connected to the 3.3V and 5V DC supplies on the Logic Tile or Core Tile.
1.2.2 Preventing damage
The tile is intended for use within a laboratory or engineering development
environment. It is supplied without an enclosure and this leaves the board sensitive to
electrostatic discharges and allows electromagnetic emissions.
Caution
To avoid damage to the board when it has logic devices mounted, observe the following
precautions.
• never subject the board to high electrostatic potentials.
• always wear a grounding strap when handling the board.
• only hold the board by the edges.
• avoid touching the component pins or any other metallic element.
Caution
Do not use the board near equipment which is:
• sensitive to electromagnetic emissions (such as medical equipment)
• a transmitter of electromagnetic emissions.
