The device stores the FPGA configuration bitstream and automatically loads it upon power-up when connected to the FPGA's AS configuration interface. It supports clock rates up to 20MHz for fast configuration times and can be reprogrammed in-system through the FPGA's JTAG interface or a dedicated programming header.","working_principle":"The EPCS64SI16N operates as a serial Flash memory optimized for FPGA configuration. **Active Serial Configuration**: When the FPGA powers up in AS mode, it drives the serial clock (DCLK) and reads configuration data from the EPCS device. The FPGA asserts nCS to select the device, then clocks out data serially on the DATA pin. The entire configuration process is controlled by the FPGA's built-in configuration controller. **Memory Architecture**: The 64Mbit array is organized as 256-byte pages within 65,536-byte sectors. Page programming writes 256 bytes at a time, while erase operations affect entire sectors. **In-System Programming**: The device can be reprogrammed through the FPGA's JTAG interface using Intel Quartus software and a USB-Blaster cable. This enables remote firmware updates without physical access to the device. **Multi-Device Chains**: Multiple EPCS devices can be cascaded to configure multiple FPGAs, with the nCS-to-nCS chaining allowing sequential access.","pin_description":"
