EPCS4SI8N from Intel\/Altera is a 4-Mbit serial configuration device for Active Serial programming of Intel FPGAs. Stores bitstream and auto-loads on power-up. 4-pin AS interface connects directly to FPGA. In-system programming via JTAG through FPGA.<\/p>\n

On power-up, FPGA drives nCS low and generates DCLK. EPCS4 outputs bitstream on DATA pin synchronized to DCLK. After configuration, FPGA asserts CONF_DONE. Reprogramming via JTAG through ASDI pin.<\/p>\n
