Freescale Semiconductor, Inc., 2005, 2006. All rights reserved. Freescale SemiconductorApplication NoteDocument Number: AN2536Rev. 2, 04/20061AbstractDesign of memory systems becomes more complex as the operation frequency increases in a low-power environment. A number of criteria should be considered to achieve maximum system performance under these conditions. The external memory bus is intended to work with PC100 grade memory. Care must be taken in board Layout to achieve a system capable of maximum bus rates at low document describes the recent investigation into the maximum memory bus frequency of a low-power memory system in terms of stability, capacitive loading, and production margin. This data will be useful to customers in their Design of low power high Speed memory systems with the applications processorsThis document applies to the following devices, collectively called throughout: MC9328MX1 MC9328MXL MC9328MXS High Speed Layout Design GuidelinesMC9328MX1, MC9328MXL, and MC9328MXSContents1 Abstract.
