Introduction

►Customers are beginning to inquire and / or expect DDR3 support

on their new product offerings, especially as the price cross-over

point nears.

►The first device with DDR3 support was 8572.

►The first development system with DDR3 will be P2020.

►As such, more and more FSL products are supporting DDR3

moving forward.

►In this session we will look at key distinctions between DDR3 vs.

DDR1 & DDR2, with key emphasis placed on elements that are

important to hardware / board design engineers.
