2.2. External Memory Protocol Support

Intel® MAX® 10 FPGAs offer external memory interface support for DDR2, DDR3, DDR3L, and LPDDR2 protocols.
Table 21.  Supported External Memory Configurations
External Memory Protocol Maximum Frequency Configuration
DDR3, DDR3L 303 MHz x16 + ECC + Configuration and Status Register (CSR)
DDR2 200 MHz x16 + ECC + Configuration and Status Register (CSR)
LPDDR21 200 MHz2 x16
1 Intel® MAX® 10 devices support only single-die LPPDR2.
2 To achieve the specified performance, constrain the memory device I/O and core power supply variation to within ±3%. By default, the frequency is 167 MHz.
