DS250DF230EVM User’s Guide
2.2.3
EEPROM Page
The SigCon Architect EEPROM page allows the user to either create a DS250DF230 Hex file that is
programmable to an EEPROM or configure a DS250DF230 device based on values from an existing
DS250DF230 Hex file.
Figure 8. EEPROM Page for DS250DF230 Profile
The user may choose to update the EEPROM page settings based on values read from the DS250DF230
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 there is a socket for a
standard 6-pin EEPROM (XU1). SigCon Architect cannot directly program the EEPROM. The EEPROM
Hex File can be burned on the EEPROM via I

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.
