Choosing a Configuration DevicefFor information on serial configuration devices, refer to SerialConfiguration Devices (EPCS1, EPCS4, EPCS16, & EPCS64) Data Sheet.The EPC2, EPC1 and EPC1441 configuration devices provideconfiguration support for Stratix series, Cyclone series, APEX II,APEX 20K, Mercury, ACEX 1K, and FLEX 10K devices. The EPC2 deviceis ISP-capable through its JTAG interface. This enables you to programthem on board for a quick and efficient prototyping environment. TheEPC2 and EPC1 can be cascaded to hold large configuration files.fFor more information on EPC2, EPC1, and EPC1441 configurationdevices, refer to Configuration Devices for SRAM-Based LUT Devices DataSheet.Choosing aConfigurationDeviceTable 1–1 summarizes the features of the Altera configuration devicesand the amount of configuration space they hold. Note that not everyconfiguration device can be used to configure every Altera device. Forexample, EPCS devices can only be used to configure Stratix II or Cycloneseries devices.Table 1–1.
