The external flash interface feature is supported in EPC4 and EPC16 devices. For more
information about using this feature in the EPC8 device, contact
EPC devices have a 3.3-V core and I/O interface. The controller chip is a synchronous
system that implements the various interfaces and features. The controller chip
features three separate interfaces:
■
■
■
A configuration interface between the controller and the Altera FPGAs
A JTAG interface on the controller that enables ISP of the flash memory
An external flash interface that the controller shares with an external processor or
FPGA implementing a Nios
embedded processor—an interface available after
ISP and configuration
