Figure 13. Timing diagrams and waveform for the SDRAM interface
Table 17 reports the timing values for the SDRAM interface
For power saving and reduced interference on the board, the SDRAM speed can be
programmed to work at half speed with respect to the internal data processing:
Full Rate SW application: the SDRAM interface works at the same frequency as the
internal data processing (HD 1.0 and HD 1.5 applications supported);
Half Rate SW application: the SDRAM interface works at half frequency with respect to
the internal data processing (only available for HD 1.0 application upon specific
request).
