Nuvoton Announces Its First eSIO Series IC – NCT6681D

NCT6681D, combining a built-in microcontroller and traditional legacy SIO functions, supports a rich set of features and targets the All-in-One PC applications, high-end motherboard applications that need the built-in microcontroller to fulfill the customized features, and any other applications that microcontroller can better execute the performance.

The microcontroller inside NCT6681D is the industrial standard 1T 8-bit microcontroller and the built-in SRAM is 8 Kbyte. The firmware code is stored in an external SPI flash and could be updated via LPC interface or PS/2 interface with special tools provided by Nuvoton. In addition to the built-in microcontroller, the features that NCT6681D implements, such as PECI (Platform Environment Control Interface), SB-TSI interface, SMBus master, DSW (Deep Sleep Well) glue logic, make it also the up-to-date IC for both Intel ® latest generation platform, Sandy Bridge, and AMD ® latest generation platform, AMD FusionTM .

Moreover, NCT6681D implements some specific features that can benefit customers even more. ErP (energy related products), a more and more popular specification to further reduce the system power consumption while in S5 state nowadays, is one of them. For the traditional legacy applications, NCT6681D is the correct choice because it supports LPC interface, Printer Port, 2 COM, KBC, and GPIO (general purpose I/O).

NCT6681D feature sets are most desirable for MB / AIO systems. Inheriting the abundant development experiences from Winbond Electronics Corp., Nuvoton has been a major supplier of the key IC components for Desktop PC motherboards, Notebook PCs, Industrial / Embedded PCs and Servers markets. Nuvoton continues to devote itself to the development of creative IC components and to invest in the development of cost effective ICs with the latest features and the best performance.
