Cyclone III Device Configuration
Configuration Scheme Overview
Cyclone® III devices support the following configuration schemes:
- Serial - To Conserve Pins
- Active Serial (AS)
- Passive Serial (PS)
- Uses an external intelligent host such as a PC or a microprocessor to control the configuration process synchronously and supply the configuration data serially to a Cyclone III device.
- JTAG
- Configures Cyclone III devices via the IEEE Standard 1149.1 interface.
- Parallel - For Faster Configuration
- Active Parallel (AP)
- Uses the Cyclone III device to control the configuration process and get the configuration data from a supported parallel flash memory.
- Fast Passive Parallel (FPP)
- Uses an external intelligent host such as a PC or a microprocessor to control the configuration process synchronously and supply the configuration data in a parallel manner to the Cyclone III device.
How to Configure Cyclone III Devices
- For Prototyping or Debugging
- Using Altera Programming Cables
- The Quartus® II programmer supports configuring Cyclone III devices directly using PS or JTAG interfaces via Altera® programming cables.
- In the Field
- Using an EPCS Device (PDF)
- The Cyclone III device gets its configuration data from the EPCS device automatically after power up. However, you need to program the EPCS device first.
- Using a Supported Parallel Flash Memory
- The Cyclone III device gets its configuration data from the supported parallel flash memory automatically after power up. However, you need to program the flash memory first.
- MAX Series Configuration Controller Using Flash Memory (PDF)
- A MAX® or MAX II device is used as a flash memory configuration controller to configure Altera FPGAs.
