FUNCTIONAL DESCRIPTION
MediaQ Incorporated
CPU Interface
The Evaluation card can be used as is in a PCI system. For other supported platforms an adapter is
installed on the back of the board mating with J2. Details of which adapters are available and how to use
them are contained in the section “Adapters” later in this document. The CPUs supported by this means
are the Intel SA-1110 and PXA2x0, Motorola Dragonball, NEC VR4121 and Hitachi SH7709/7750. Care
should be taken to ensure that pins A1/B1/C1 match on the main board and adapter. When used in a PCI
system, the adapters must be removed or damage can occur to the Evaluation board and/or system. The
user must support the panel, Evaluation Board (non-PCI environment) and adapter to avoid undue strain
on the various connectors.
Flat Panel Interface
The Evaluation board has three connectors intended for interfacing to a variety of flat panel displays.
Connector U1 is used to interface directly to a Sharp HR TFT display (LQ039Q2DS54 or equivalent).
The Evaluation board has all the necessary power and power sequencing circuitry necessary for this panel.
The Sharp HR TFT flat panel cable can be connected to the Evaluation board as follows:
§ Lift the brown lever on the HR TFT socket (U1)
§ Insert flat cable with exposed portion facing up over the lever and under the top of the socket
§ Push down the brown lever – this should lock the cable into place and make electrical connection
Two Generic Flat Panel connectors (J3 and J5) are provided to allow the Evaluation board to be interfaced
with a wide variety of LCD panels other than the Sharp HR TFT. Custom cables are required to map the
panel signals onto the proper MQ-1168 pins, details of the LCD panels already verified by MediaQ can be
obtained from our web site. A custom cable will require a matching female connector to mate with either
of the 60-pin connectors J3 or J5, these connectors also supply various power rails. The connector J3 is a
50-mil, 2x30 male connector and J5 is a 0.1” 2x30 standard header. The matching female 50 mil spaced
connector part number is M50-3003022. The mating connector for the 0.1” header is readily available in
many variations.
The pin assignments for the generic connectors are the same and shown below:

The diagram above shows the adapter for the Palm Development Platform (Hurricane) or the Motorola
Development Platform. As with the other adapters, J2 mates with the “Generic CPU” connector located
on the back of the Evaluation board. Connector U4 mates with the 96-pin female DIN connector on the
Palm Hurricane Platform. Alternately, connector U6 can be used to connect to the Motorola
Development Platform. These connectors are keyed so cannot be installed incorrectly. J1 selects which
IRQ the MQ-1168 will connect to on the platform. Setting 1-2 selects IRQ2 while 2-3 selects IRQ3. The
Evaluation board requires 3.3V and 5V power from the adapter board. The Palm/Motorola adapter passes
the 3.3V power supplied on the platform connector but does not provide 5V. Connector JP1 is used to
provide 5V and can be connected to an external source. A wire with a mating female 0.25” square
connector can be attached to the 5V supply which does not go to the bus but is available on the platform.
The diagram below shows how the Evaluation board, adapter board and Palm or Mororola platforms are
connected. Care should be taken to line up the pins correctly, especially A1/B1/C1.
