The product embeds two DDRSDR controllers: DDRSDRC0 and DDRSDRC1.
Figure 20-1. DDRSDR Controllers
DDRSDRC0 is a multi-port DDRSDR controller, standalone. It supports only DDR2 and LP-DDR devices. Its
user interface is located at 0xFFFFE600.
DDRSDRC1 is a single-port DDRSDR controller, embedded in EBI. It supports DDR2, LPDDR, SDR and LP-
SDR devices. Its user interface is located at 0xFFFFE400.
Both are described in Section 22. ”DDR/SDR SDRAM Controller (DDRSDRC)”.
All references to SDR and LPSDR must be ignored for DDRSDRC0, multi-port DDRSDR controller.
All references to multi-port must be ignored for DDRSDRC1, DDRSDR controller embedded in EBI.
