Guide
The Generic Serial Flash Interface Intel
®
FPGA IP core provides access to Serial
Peripheral Interface (SPI) flash devices. The Generic Serial Flash Interface IP is a
more efficient alternative compared to the ASMI Parallel and ASMI Parallel II Intel
FPGA IP cores. The Generic Serial Flash Interface Intel FPGA IP core supports Intel
configuration devices as well as flash from different vendors. Intel recommends you to
use the Generic Serial Flash Interface Intel FPGA IP core for new designs.
You can use the Generic Serial Flash Interface IP to write the following data to the
flash device:
• Configuration memory
(1)
—configuration data for Active Serial (AS) configuration
scheme
• General purpose memory— application-specific data
The Generic Serial Flash Interface IP supports the following features:
• Single, dual or quad I/O mode
• Direct flash access via the Avalon Memory Mapped (Avalon-MM) slave interface
which allows the controller to directly execute codes from the flash
• Up to 3 multiple flash device support (Intel Arria
®
10 and Intel Cyclone
®
10 GX
devices only)
• Generic control register for accessing flash control status registers
• Programmable clock generator with run-time baud rate change for device clock
• Programmable chip select delay
• Read data capturing logic when running with high frequency
• FPGA active serial memory interface (ASMI) block atom connection to the active
serial (AS) pins or export to FPGA I/O pins
