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:
■
I2C 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.
I2C EEPROM
Board reference U6 is a footprint to mount an I2C EEPROM device onto the
development board.
Table 2–19 lists the I2C 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.
