Cyclone III Device Passive Serial Configuration
You can perform passive serial (PS) configuration using an Altera® download cable, or an intelligent host such as a microprocessor, or a MAX® or MAX II CPLD. During PS configuration, data is transferred from a flash memory, or other storage device to the Cyclone® III device on the DATA[0] pin. This configuration data is latched into the FPGA on the rising edge of DCLK. Configuration data is transferred at a rate of one bit per clock cycle. The maximum DCLK frequency supported by the Cyclone III device is 100 MHz.
Configuration Methods in Passive Serial Mode include:
- Using a download cable for in-system programmability (ISP) and prototyping
- Using a MAX II device as an external host
- Using a microprocessor
