Appendix F. DDR400 Interface using the LatticeEC Evaluation Board
The DDR400 interface was implemented using the LatticeEC20 device on the LatticeEC Advanced Evaluation
Board. Figures 10-21, 10-22 and 10-23 show the READ, WRITE and WRITE to READ transition operations running
at 200MHz. For more information on the evaluation board, refer to LatticeEC Advanced Evaluation Board User’s
Guide available on the Lattice web site at www.latticesemi.com.
Figure 10-21. READ Function Running at 200MHz
Note: An extra READ command is implemented in the LatticeEC20 device to protect the data during postamble.
This extra READ is not required for other LatticeEC devices. Refer to the DQS Postamble section of this document
for more information.
