Programming Serial Configuration Devices

Serial configuration devices are non-volatile, flash-memory-based devices. You can

program these devices in-system using the USB-Blasterâ¢, EthernetBlasterâ¢, or

ByteBlasterâ¢ II download cable. Alternatively, you can program them using the

Altera programming unit (APU), supported third-party programmers, or a

microprocessor with the SRunner software driver.

You can perform in-system programming of serial configuration devices using the

conventional AS programming interface or the JTAG interface solution.

Because serial configuration devices do not support the JTAG interface, the

conventional method to program them is using the AS programming interface. The

configuration data used to program serial configuration devices is downloaded using

programming hardware.

During in-system programming, the download cable disables device access to the AS

interface by driving the nCE pin high. Stratix IV devices are also held in reset by a low

level on nCONFIG. After programming is complete, the download cable releases nCE

and nCONFIG, allowing the pull-down and pull-up resistors to drive GND and VCCPGM,

respectively. Figure 10â9 shows the download cable connections for the serial

configuration device.

Altera has developed Serial FlashLoader (SFL), an in-system programming solution

for serial configuration devices using the JTAG interface. This solution requires the

Stratix IV device to be a bridge between the JTAG interface and the serial

configuration device.

f For more information about SFL, refer to AN 370: Using the Serial FlashLoader with

Quartus II Software.
