1.13 FPGA General Purpose I/O
The MAX 10 I/O buffers support a range of programmable features.
These features increase the flexibility of I/O utilization and provide an alternative to
reduce the usage of external discrete components such as a pull-up resistor and a PCI
clamp diode.
1.14 External Memory Interface
Dual-supply 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 MAX 10
devices.
