1.11.1. Hard and Soft Memory Controllers

Arria® V GX,GT, SX, and ST devices support up to four hard memory controllers for DDR3 and DDR2 SDRAM devices. Each controller supports 8 to 32 bit components of up to 4 gigabits (Gb) in density with two chip selects and optional ECC. For the Arria® V SoC devices, an additional hard memory controller in the HPS supports DDR3, DDR2, and LPDDR2 SDRAM devices.

All Arria® V devices support soft memory controllers for DDR3, DDR2, and LPDDR2 SDRAM devices, QDR II+, QDR II, and DDR II+ SRAM devices, and RLDRAM II devices for maximum flexibility.

Note: DDR3 SDRAM leveling is supported only in Arria® V GZ devices.
