External Memory Interface

Dual-supply Intel® MAX® 10 devices feature external memory interfaces solution that uses the I/O elements on the right side of the devices together with the UniPHY IP.

With this solution, you can create external memory interfaces to 16-bit SDRAM components with error correction coding (ECC).

Note: The external memory interface feature is available only for dual-supply Intel® MAX® 10 devices.
Table 11.  External Memory Interface Performance
External Memory Interface3 I/O Standard Maximum Width Maximum Frequency (MHz)
DDR3 SDRAM SSTL-15 16 bit + 8 bit ECC 303
DDR3L SDRAM SSTL-135 16 bit + 8 bit ECC 303
DDR2 SDRAM SSTL-18 16 bit + 8 bit ECC 200
LPDDR2 SDRAM HSUL-12 16 bit without ECC 200 4
3 The device hardware supports SRAM. Use your own design to interface with SRAM devices.
4 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.
