Connection Summary

There are two types of display module used on the SAMA5D2, SAMA5D3 and SAMA5D4 Xplained board, TM43xx, TM7000.

To get the correct color display on LCD, please use the connection in the following table.

Ribbon Cable

We select one of the following ribbon cables to connect the display module to the board.

  • Directly Connect Cable

    For more details on this cable, please refer to TM7000 Adaptor Cable.

Configuration of Display Module

TM7000 has options to support two different 18 bits RGB parallel data interfaces:

  • Default Configuration
    • The default configuration of TM7000, where R46-R63 are populated with 0R resistors, and R27-R44 are left open.

    • To be used with SAMA5D3 Xplained with the Directly Connect Cable.
  • Alternative Configuration
    • You need to change TM7000 by keep R46-R63 open, and R27-R44 are populated by 0R resistors.

    • To be used with SAMA5D2 and SAMA5D4 Xplained with the TM7000 Adaptor Cable.

TM43xx

The TM43xx display module uses a 5 VCC power supply. It has 24-bit RGB parallel data interface, use the Directly Connect Cable to connect the board and the display module.

The connection is identical for the SAMA5D2, SAMA5D3, SAMA5D4 Xplained board. Here we take the SAMA5D2 Xplained board for example.

On SAMA5D2 Xplained Board

Please follow the following steps to connect the board and the display module.
  1. Connect the Directly Connect Cable to the Host Interface(J5) on the TM43xx. Note that connects on the cable face DOWN toward PCB.

  2. Connect the Directly Connect Cable to SAMA5D2 Xplained LCD Connector (J2). Note that contacts on the cable face UP away from PCB.

TM7000

The TM7000 display module uses a 3.3 VCC power supply. It has 18-bit RGB parallel data interface. The pin assignment of the RGB bus of SAMA5D2 and SAMA5D4 is different from SAMA5D3. The connection of the board and the display module is different between the SAMA5D3 and the SAMA5D2, SAMA5D4 Xplained board.

On SAMA5D2/SAMA5D4 Xplained Board

The connection is identical for the SAMA5D2, and SAMA5D4 Xplained board. Here, we take the SAMA5D2 Xplained board as the example.

We need to use TM7000 with the alternative configuration and the TM7000 Adaptor Cable. Please follow the following steps to connect the board and display module.

  1. Connect the TM7000 Adaptor Cable to the Host Interface(J6) on the TM7000. Note that connects on the cable face DOWN toward PCB, and make sure that LCD written on the ribbon cable silkscreen at the back of the TM7000 connector.

  2. Connect the TM7000 Adaptor Cable to SAMA5D2 Xplained LCD Connector (J2). Note that contacts on the cable face UP away from PCB, you can see the ribbon cable silkscreen facing you with CPU written in front of the Xplained connector.

On SAMA5D3 Xplained Board

Using TM7000 with the default configuration and the Directly Connect Cable, follow the following steps to connect the board and the display module.

  1. Connect the Directly Connect Cable to the Host Interface(J6) on the Display Module. Note that connects on the cable face DOWN toward PCB.
