White Paper: BOM Cost Reduction by Removing S3 State

BOM Cost Reduction: Remove Intel® Atom™ Processor E6xx S3 State

Executive Summary
In today’s embedded design, designers are increasingly concerned with reducing system power. When systems experience extended periods of idle time, power can be greatly reduced when a processor transits into System Sleeping Power States (S-States). With the additional S-States to support, this means additio...nal power rails need to be supplied by the platform and incur extra components such as voltage regulator, switches, etc.

In reality, there are applications that do not require extra sleep states due to performance demand and its usage environment. Having extra sleep states translates into extra components and increased Bill of Materials (BOM) cost. With the understanding that Intel® Atom™ processor E6xx can be positioned in multiple segments, this idea of removing additional power rails can be adopted in segments such as industry control and In-Vehicle-Infotainment (IVI).

This document presents an overview of system power states in the Intel Atom processor E6xx, and shows the remaining power rails after removal of the S3 power state. The estimated BOM cost savings is also shown to highlight the benefits of removing the S3 power state.
