Enhanced Configuration (EPC) Devices Datasheet

January 2012

Altera Corporation

EPC devices support three different types of flash memory. Table 3 lists the supported

flash memory for all EPC devices.

information about using this feature in the EPC8 device, contact Altera Applications

24/7 Technical Support.

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

ISP and configuration
