FPP Configuration

The FPP configuration in Cyclone IV devices is designed to meet the increasing

demand for faster configuration time. Cyclone IV devices are designed with the

capability of receiving byte-wide configuration data per clock cycle.

You can perform FPP configuration of Cyclone IV devices with an intelligent host,

such as a MAX II device or microprocessor with flash memory. If your system already

contains a CFI flash memory, you can use it for the Cyclone IV device configuration

storage as well. The MAX II PFL feature in MAX II devices provides an efficient

method to program CFI flash memory devices through the JTAG interface and the

logic to control configuration from the flash memory device to the Cyclone IV device.

f For more information about the PFL, refer to AN 386: Using the Parallel Flash Loader

with the Quartus II Software.

1 FPP configuration is supported in EP4CGX30 (only for F484 package), EP4CGX50,

EP4CGX75, EP4CGX110, EP4CGX150, and all Cyclone IV E devices.

1 The FPP configuration is not supported in E144 package of Cyclone IV E devices.

1 Cyclone IV devices do not support enhanced configuration devices for FPP

configuration.
