Principio de funcionamiento
The EPCQ-A stores FPGA configuration data in quad SPI flash. Active Parallel mode uses 4 data lines (DATA0-DATA3) plus DCLK for 4x faster configuration compared to serial devices. The FPGA asserts nCS, and the EPCQ-A streams configuration data on rising DCLK edges. AS (Active Serial) mode is also supported for backward compatibility. The device supports sector erase and page programming for in-system updates via JTAG or the FPGA ASMI (Active Serial Memory Interface) peripheral.
Aplicaciones
- FPGA config storage
- Active Parallel config
- Remote updates
