Flash Memory (U17)
U17 is a 16-Mbyte AMD AM29LV128M flash memory device connected
to the Stratix II device. It can be used for two purposes:
■ A Nios II embedded processor implemented in the Stratix II device
can use the flash as general-purpose readable memory and
nonvolatile storage.
■ The flash memory can hold a Stratix II device configuration file that
is used by the configuration controller to load the Stratix II device at
power-up.
Refer to Table 2–21 for Stratix II pin-outs for flash memory device U17.
Hardware configuration data that implements the sines reference design
is prestored in this flash memory and configures the Stratix II device with
this design on boot up. A Nios II reference design can identify the 16-
Mbyte flash memory in its address space, and can program new data
(either new Stratix II configuration data, Nios II embedded processor
software, or both) into flash memory. For an example of programming
the flash memory, refer to
“Programming Example for the 2S180 DSP
Development Board” on page 2–6 .
