DESCRIPTION
The DC2347A contains only those functions necessary
to safely program and verify the
EEPROM. It serves no other purpose. The DC2347A holds
the LTC2937 in a clamshell socket for convenient access
and replacement of parts. The LTpowerPlay™ GUI software,
running on a PC, provides a simple interface to program
and verify the EEPROM with a user supplied configuration.
What Can You Do with The DC2347A
• Program the contents of the EEPROM with your project
or HEX file.
• Verify the contents of the EEPROM against your project
or HEX file.
• Verify the contents of the EEPROM against factory
defaults.
