DDRSDRC0 Multi-port DDRSDR Controller
Description
The product embeds two DDRSDR controllers: DDRSDRC0 and DDRSDRC1.
Figure 20-1. DDRSDR Controllers
Both are described in
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.
The DDR2 Controller is dedicated to 4-port DDR2/LPDDR support. Data transfers are performed
through a 16-bit data bus on one chip select. The DDR2 Controller operates with 1.8V Power
Supply (VDDIOM0).
• DDRSDRC0 is a multi-port DDRSDR controller, standalone. It supports only DDR2 and LP-
• DDRSDRC1 is a single-port DDRSDR controller, embedded in EBI. It supports DDR2,
DDR devices. Its user interface is located at 0xFFFFE600.
LPDDR, SDR and LP-SDR devices. Its user interface is located at 0xFFFFE400.
