1.1.2.1. External Memory Interface (EMIF) Maximum Frequency Specification Updage

Description

To achieve timing closure, the EMIF maximum frequency specification has been updated in the table below.

Table 4.   Cyclone® V EMIF Maximum Frequency Specification Update
Note: In this table, the stated performances apply to component topology only. The DIMM topology is not supported on the hard controller.
Note: For changes to other variants and slower speed grades, refer to the External Memory Interface Spec Estimator.
