This page has details on each of the system components that make up the Quartz Development Kit.
The block diagram below shows the main components. Click the image to enlarge.
Quartz CPU Module
The Quartz CPU Module is at the core of the QDK. Quartz includes a Freescale Vybrid VF6xx processor with Cortex-A5 and Cortex-M4 ARM cores. There is also 256MBytes DDR3 RAM, 256MBytes NAND flash and dual 10/100 Ethernet PHYs. The module and dev kit connect using two 100-pin Hirose connectors.
The connectors on the QDK are Hirose FX11A-100P-SV0.5.
User Interface Components
Audio
Stereo audio output is provided on a 3.5mm jack connector. This is driven by a Freescale SGTL5000 codec. The microphone input, line input and line output signals from the codec are available on teh 51-way expansion connector.
User I/O
The QDK includes the following application accessible buttons and LEDs:
| Button/LED | GPIO Pin |
|---|---|
| BUTTON1 | PTD24 |
| BUTTON2 | PTD25 |
| LED1 (Green) | PTD29 |
| LED2 (Red) | PTD30 |
Touch Controller
A Freescale CRTOUCH chip is included on the QDK and provides resistive touch screen functionality as well as 4 capacitive touch buttons. It interfaces to the Vybrid chip via the I2C2 bus.
Accelerometer
The QDK includes a Freescale MMA8451Q accelerometer connected to the Vybrid via the I2C3 bus. INT1 from the accelerometer is connected to PTA23 on the Vybrid.
Display and Video Input
7" TFT LCD Interface
The QDK ships with an optional 800x480 7" Datavision DTFS070A5SHLA-D02 TFT display. This panel includes a 4-wire resistive touch screen that is also supported on the development kit.
LVDS Interface
A LVDS transmitter chip is included on the QDK and interfaces to a 30-way connector. This is identical to the connector on the Device Solutions Opal Development Kit and the i.MX53 Quick Start Board (QSB) and supports the Freescale 10.1" LVDS-1 display with capacitive touch. It can be purchased from Freescale here.
Composite Video In
The Vybrid processor includes 4 video inputs for composite signals. Two of these are available on RCA connectors and the remainign two can be accessed via the 51-way expansion connector.
