1.2. MAX® 10 I/O Vertical Migration Support

Figure 1. Migration Capability Across MAX® 10 Devices
  • The arrows indicate the migration paths. The devices included in each vertical migration path are shaded. Non-migratable devices are omitted. Some packages have several migration paths. Devices with lesser I/O resources in the same path have lighter shades.
  • To achieve the full I/O migration across product lines in the same migration path, restrict I/Os usage to match the product line with the lowest I/O count.


Note: Before starting migration work, Altera recommends that you verify the pin migration compatibility through the Pin Migration View window in the Quartus® Prime software Pin Planner. For example, not all MAX® 10 devices support 1.0 V I/O.
