This chapter describes the memory interface pin support and the external memory
interface features of Cyclone
In addition to an abundant supply of on-chip memory, Cyclone IV devices can easily
interface with a broad range of external memory devices, including DDR2 SDRAM,
DDR SDRAM, and QDR II SRAM. External memory devices are an important system
component of a wide range of image processing, storage, communications, and
general embedded applications.
Altera recommends that you construct all DDR2 or DDR SDRAM external memory
interfaces using the Altera
controller function using the Altera DDR2 or DDR SDRAM memory controllers,
third-party controllers, or a custom controller for unique application needs.
Cyclone IV devices support QDR II interfaces electrically, but Altera does not supply
controller or physical layer (PHY) megafunctions for QDR II interfaces.
This chapter includes the following sections:
