    WM8505 System Overview
    The WM8505 Application Processor is the SoC solution with superior networks and display capabilities that specially tailored for cost-effective embedded multimedia devices. The WM8505 supports display resolution
    up to 1024x600 and 10/100 Ethernet MAC. The WM8505 is a low power consumption SoC solution that demands 1.8V for DDR2 SDRAM, and 3.3 V for other interfaces as operating power. The WM8505 integrates multimedia features and functionalities, e.g. decoding popular audio/video streams, 2D graphics display, and peripheral I/Os that are aiming to meet upcoming market demands as well as reduce customer’s total
    BOM cost. The WM8505 is designed to deliver the state-of-the-art performance for applications such as Networked Projector, Digital Signage, and Thin-Client Terminal.
    The WM8505 Application Processor integrates all popular peripherals in an efficiently architected RISC (reduced instruction set computer) platform. Figure 1 illustrates the system block diagram of WonderMedia's WM8505 Application Processor.
