product brief Intel® MD566X for ISA, Serial, and PCMCIA Overview M O D E M S I L I C O N OPERATIONS The Intel® MD566X is an enhancement of the MD565X chipset. Due to advancements in architecture the DSP no longer requires 64K of external SRAM. This new technology improves performance while decreasing board size, power consumption, and cost. The MD566X meets PC-based communications requirements for internal, external, and PCMCIA applications. It meets Microsoft* PC 98 specifications for Windows* and legacy applications. It also supports AT commands for data, Voice IS-101, and Fax Class 1. The MD566X owes its capabilities to the sophisticated architecture of its controller and DSP. Each component’s highly integrated design minimizes part count and board area. The MD566X serves multiple levels of product, from basic feature sets to full-featured speakerphone applications. With its powerful controller and DSP the MD566X offers excellent performance for today’s most demanding applications. This high performance V.90 solution delivers robust data, fax, and voice features—including full-duplex speakerphone. The single-platform design means that no additional circuitry is needed to support ISA, Serial, or PCMCIA interfaces and a host of features.
