Chapter 1: Enhanced Configuration Devices (EPC4, EPC8, and EPC16) Data Sheet
Functional Description
Configuration Handbook (Complete Two-Volume Set)

Altera Corporation
The external flash interface is currently supported in the EPC16 and EPC4 devices.
For information about using this feature in the EPC8 device, contact Altera Applica-
tions at www.altera.com/support.
Enhanced configuration 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.
Figure 1–1 shows a block diagram of the enhanced configuration device. 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 (interface available after ISP
and configuration)
