DS280DF810EVM User’s Guide
2.2.3
EEPROM Page
The SigCon Architect EEPROM page allows the user to either: create a DS280DF810 Hex file that is
programmable to an EEPROM, or configure a DS280DF810 device based on values from an existing
DS280DF810 Hex file.
Figure 8. EEPROM Page for DS280DF810 Profile
The user may choose to update the EEPROM page settings based on values read from the DS280DF810
device by clicking “Update Slot from Device”. To create the programmable hex file, click “Write to
EEPROM Hex”. Note that the evaluation module does not include an EEPROM, but an external EEPROM
can be used. SigCon Architect cannot directly program the EEPROM. The EEPROM Hex File can be
burned on the EEPROM via I
2
C communication (i.e. AARDVARK or equivalent interface adapter). The
EEPROM control settings are described in greater detail below.
•
Common Channel: If this box is checked, all channels receive the same configuration. Different
devices can receive different configurations, but within one device, all channels will receive the same
configuration. If this box is unchecked, then the EEPROM will store the configuration as unique
channel configurations. Each of the four channels can receive a unique configuration.
•
EEPROM>256:
–
This setting must be enabled if there are more than 4 EEPROM slots.
–
When this box is checked, the
EEPROM Size
drop down menu is automatically populated by 512
Bytes if previously populated by 256 Bytes.
–
When this box is unchecked, the
EEPROM Size
drop down menu is automatically populated by 256
Bytes. Up to 4 EEPROM slots can be programmed.
•
Enable CRC: If enabled, each device will have a CRC value specific to the base header, address map
header, and data. If disabled, the CRC is not computed.
•
Slot Update Details: The number of slots refers to the total number of unique SMBus register settings
to load from the EEPROM. The user can choose to update all slots, or which slot # to update the
SigCon Architect EEPROM page from.
