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.
