This chapter explains the architecture of the OMAP4430 PandaBoard.
2.1
Shown in Figure 1 is the Architectural Block Diagram of the OMAP4430 PandaBoard.
Listed below are the major components used on the PandaBoard.
The Platform also includes connectors that can be used for additional functionality and/or expansion
purposes. These connectors are not populated on the platform, but can be installed by the user. They are
indicated by the blue blocks in Figure 1, and include:
See Figure 2 on page 16 for a top side view of the Panda Platform.
The core components of the PandaBoard will be discussed in this section of the document. This would
include the OMAP4430 Processor and its POP LPDDR2 memory, the input clock circuitry, the TWL6030
Power Companion IC, and the TWL6040 Audio Companion IC. The functional interfaces will be
discussed in later sections of the document.
