Flash Memory
(U5)
Altera Corporation
May 2007
U5 is an 8-bit, 16 Mbyte AMD flash memory device connected to the
FPGA. Depending on the board revision, the part number is
AM29LV128M or S29GL128M10TFIR1. Refer to
between the FPGA and the flash memory chip. U5 can be used for two
purposes:
1.
2.
A Nios II processor design in the FPGA can identify the 16 Mbyte flash
memory in its address space, and can program new data (either new
FPGA configuration data, Nios II software, or both) into flash memory.
The Nios II development software includes subroutines for writing and
erasing flash memory.

FPGA Pin
A Nios II embedded processor implemented on the FPGA can use
the flash memory as general-purpose memory and non-volatile
storage.
The flash memory can hold FPGA configuration data that is used by
the configuration controller to load the FPGA at power-up. Refer to
“Configuration Controller Device (U3)” on page 2–33
information.
The flash memory device shares address and data connections
with the Ethernet MAC/PHY device.
