External Memory  
External Memory  
Arria V devices support up to four hardened memory controllers for DDR3 and  
DDR2 SDRAM. Each controller supports 8- to 32-bit components up to 4 gigabits (Gb)  
in density with two-chip select and optional ECC. Arria V devices do not support  
DDR3 SDRAM leveling.  
Arria V devices also support soft memory controllers for DDR3, DDR2, LPDDR2, and  
LPDDR SDRAM, RLDRAM II, QDR II, and QDR II+ SRAM for maximum flexibility.  
Table 1–7 lists the external memory interface block performance.
