Table 2–18 lists the user-defined LED component reference and the manufacturing
information.
Off-Chip EEPROM
This section describes the board's EEPROM interface support and also their signal
names, types, and connectivity relative to the MAX V CPLD device. The board
include footprints for you to mount the following EEPROM device:
■ I 2 C EEPROM
■ SPI EEPROM
1 The MAX V CPLD development board only provide the EEPROM device footprints.
However, the board test system EEPROM function is developed based on the
EEPROM components described in this section.
I 2 C EEPROM
Board reference U6 is a footprint to mount an I 2 C EEPROM device onto the
development board.
Table 2–19 lists the I 2 C EEPROM device pin assignments, signal names, and functions.
The signal names and types are relative to the MAX V CPLD device in terms of I/O
setting and direction.
