Enhanced Configuration Devices Flash Memory (Part 2 of 2)DeviceEPC4Intel Flash (1)Micron FlashFlash MemoryNote to Table 2–1:(1) Refer to Process Change Notice PCN0506: Addition of Intel Flash Memory As Sourcefor EPC4, EPC8 & EPC16 Enhanced Configuration Devices.1 The external flash interface is currently supported in the EPC16and EPC4 devices. For information on using this feature in theEPC8 device, contact Altera Applications.The enhanced configuration device has a 3.3-V core and I/O interface.The controller chip is a synchronous system that implements the variousinterfaces and features. Figure 2–1 shows a block diagram of theenhanced configuration device. The controller chip features threeseparate interfaces:■■■A configuration interface between the controller and the AlteraFPGA(s)A JTAG interface on the controller that enables in-systemprogrammability (ISP) of the flash memoryAn external flash interface that the controller shares with an externalprocessor, or FPGA implementing a Nios ® embedded processor(interface available after ISP and configuration)Altera Corporation 2–3May 2007 Configuration Handbook, Volume 2
