CF52001-2.0
During device operation, Altera® FPGAs store configuration data SRAM cells. Because SRAM memory volatile, SRAM cells must loaded with configuration data each time device powers configure Stratix® series, Cycloneseries, APEXII, APEX 20K, MercuryTM, ACEX® FLEX® 10K, FLEX 6000 devices using data stored Altera configuration device. Altera configuration devices offered different densities provide variety features. Altera enhanced configuration devices (EPC16, EPC8, EPC4) support single-device configuration solution high-density FPGAs, including Stratix series, Cyclone series, APEX APEX 20K, Mercury, ACEX FLEX devices. enhanced configuration devices ISP-capable through Joint Test Action Group (JTAG) interface. Enhanced configuration devices cannot cascaded flash interface pins shared between multiple enhanced configuration devices implementing shared interface. enhanced configuration devices divided into major blocks, controller flash memory. Because large flash memory size decompression feature, enhanced configuration devices hold configuration data multiple Altera FPGAs. addition, unused portions flash used memory storage programmable logic device (PLD) processor (e.g., Nios® processor). After configuration, access flash memory through external flash interface enhanced configuration devices. Fast passive parallel (FPP) configuration, where configuration data sent byte-wide DATA[7.0] pins every clock cycle, also supported fast configuration times. configuration supported Stratix series, APEX devices.
information enhanced configuration devices, Enhanced Configuration Devices (EPC4, EPC8 EPC16) Data Sheet Using Altera Enhanced Configuration Device. Altera serial configuration devices (EPCS4 EPCS1) support single-device configuration solution Stratix FPGAs Cyclone series. Serial configuration devices offer cost, count configuration solution Stratix FPGAs Cyclone series. serial configuration devices cannot cascaded. Unused portions flash accessed using Nios processor.

choose appropriate configuration device, need determine total configuration space required your target FPGA chain FPGAs. These numbers listed each device family section. configuring chain FPGAs, need configuration file size each FPGA determine total configuration space needed. example, configuring EP20K200E EP20K60E device daisy chain, your total configuration space requirement would 1.964 Mbits .641 Mbits 2.605 Mbits. Next, Table determine which configuration device fulfills your configuration space requirements. Using example above, configure EP20K400E EP20K60E device chain, 2.605 Mbits would three EPC1 devices, EPC2, EPC4 device. Only EPC2 EPC1 devices cascaded. Using configuration file size tables each device family section along with Table 1-1, determine number configuration devices required configure your target FPGA chain FPGAs.
