Table 2–43 lists the flash component reference and manufacturing information.
EEPROM
A 32-Kbit I 2 C serial EEPROM is accessible from the Cyclone III LS device. The
EEPROM speed is between 100 KHz and 400 KHz.
Table 2–44 lists the EEPROM pin assignments, signal names, and functions. The signal
names and types are relative to the Cyclone III LS device in terms of I/O setting and
direction.
