XCF04SVOG20C Configuration Modes and Interfaces
Supported FPGA Configuration Modes
The XCF04SVOG20C Platform Flash PROM supports multiple configuration modes to accommodate various system architectures:
Master Serial Mode
In Master Serial configuration mode, the XCF04SVOG20C generates the configuration clock signal and controls the timing of data transfer to the target FPGA. This mode is ideal for standalone applications where the PROM directly drives the FPGA configuration process.
Slave Serial Mode
Slave Serial mode allows an external controller or processor to manage the configuration clock, providing flexibility in multi-device systems. The XCF04SVOG20C responds to clock signals while delivering configuration data synchronously.
