1 Functional Description The Universal Front Board, short UFB, provides interfaces to different display modules, where the current version supports a 128x64 pixel Matrix VFD display and a 1-line VFD display. The Front Board with the respective display represents a stand-alone control solution that is intended for CD Players and DVD Players.

Figure 1 System Block Diagram

1.1 General The UFB is usually supplied by 5V, but it is also possible to use 8V as a power supply to the board. The board is equipped with an ARM7 LPC2136 CPU. It runs RTOS at a CPU core frequency of 60MHz and offers various interfaces such as UART, I2C or SPI for communicating directly to e.g. CD or DVD player modules. Depending on which display is assembled, the display can either be controlled by I2C, SPI or by a parallel bus interface. The internal flash of the LPC microcontroller can be re-programmed using the Serial Programming Interface Connector and a standard RS232 cable. Currently StreamUnlimited does not provide final production images for reflashing at customer side but depending on the licensing scheme, this can be arranged.

The technology of the board is a single-sided Reflow PCB, having the SMD components placed on the bottom side and the display mounted on the top side.

1.2 Power Concept CON14 is the main power connector of the UFB. Figure 2 shows the power concept and the stuffing option J2, which needs to be assembled in case the board is supplied by 8V only. Supplying the board with only 5V is recommended due to lower power dissipation.

Note that the Board can either be supplied by 5V or by 8V. It is not foreseen to apply both supplies at the same time (!).

embedded innovation 1.3 Connections Figure 3 shows the connectors and the connector types of the UFB. The JTAG connector is an option only and will not be stuffed on the production boards. It is not required to assemble a socket for the Matrix VFD, because this display is directly soldered to the UFB.

1.4 Block Diagram, System Architecture

Figure 4 System Architecture

Figure 4 shows the system architecture of the UFB. The input clock frequency is 12MHz, a 32.768kHz clock can be assembled for the RTC, but it’s not available in the default version. Level shifting is required for the communication from the CPU to the display modules. A dedicated power switch enables or disables the 5V power supply for the display modules.

1.5 KeyPad Board – for reference only - An example KeyPad Board provided as part of the development kit is shown in Figure 5. It is assembled with 11 tact switches, providing the most common used control functions. There’s also an IR Receiver available and a green and a red SMD LED.

embedded innovation Figure 6 shows the schematics of the example KeyPad Board with the voltage divider ratios for the respective key functions. Note that the two 47K resistors R29 and R38 are not assembled on the KeyPad Board, but on the main Universal Front Board. This avoids floating inputs in case no KeyPad board is connected.

Figure 6 KeyPad Schematics

1.6 RS232 Interface Board – for reference only - There is a reference RS232 Interface Board available that can be used for programming the LPC2136. Figure 7 shows how the board looks like. SW14 is the Reset switch; SW13 is used for pulling P0.14 to GND and thereby initiating the flashing process.

4 CD80 Development Kit Setup Figure 12 depicts the CD80 Development Kit Setup with a UFB, which is also available at StreamUnlimited. The so-called “CD80 Adapter Board” and the “Audio Interface Board is available as a single Board implementation, thus minimizing the Setup efforts. The “Serial Programming Interface Board” is added to the Development Kit in order to provide the customer a way for simple SW Upgrades via RS232. For a final product this Board it is not required. The KeyPad Board with the IR Receiver and two indication LEDs provides the interface for controlling the setup.

4.1 CD80 Development Kit Connection Diagram A detailed connection diagram is shown in Figure 13. It highlights all interfaces required for the Setup and all relevant Pin functions that are necessary for successful communication. For instance, the CD80 module is controlled via I2C from the UFB, which is why those control lines are especially highlighted in Figure 13.

4.2 CD80 Final Product Example with an UFB An example of how a block diagram of a final product with the CD80 and the UFB could look like is shown in Figure 14. The device is controlled by the UFB, where the KeyPad Board with the IR Receiver and the indication LEDs is connected. The UFB can put all other components of the setup into sleep mode or – depending on the implementation – completely switch off all other parts. This can be done by the POWER_ON signal, which is active high. The UFB is either supplied by 5V or by 8V.
