Freescale MCF547x/8x DDR‑SDRAM Layout Considerations Application Note
The document describes the DDR‑SDRAM controller integrated in the MCF547x/8x ColdFire microprocessor families and explains how the controller operates at half the core frequency (e.g., 133 MHz for a 266 MHz core). It outlines the memory architecture, supported address widths, chip‑select capabilities, and the maximum memory size that can be accessed.
Detailed layout guidelines are given, including recommended trace lengths, termination resistor values, routing on ground‑adjacent layers, and VREF considerations. Validation board schematics and PCB stack‑up information are provided to illustrate proper implementation.
