CDCE925: program the EEPROM from a Windows PC without using ClockPro

Part Number: CDCE925
Other Parts Discussed in Thread: CLOCKPRO, CDCM6208


Are there any off the shelf solutions for programming the EEPROM without going through ClockPro?

I want my users to easily switch through a handful of configurations with only one click.

Is there any existing tool that can do that? Failing that, is there any API around which I could build my own tool?

  • Hello David,

    The CDCE9xx devices do support in system programming, so if you had some other non-volatile storage for multiple configs, you could then program the specific config of interest to the EEPROM... However you would eventually wear out the EEPROM, datasheet rates it for 1000 programmings.

    What you are better of doing is simply directly programming those several configs from a MCU or some other logic device for each click without using the EEPROM.

    Please also see, General I2C / EEPROM usage for the CDCE(L)9xx family.

    Note there is an example for using an MSP430 to program the settings into a CDCM6208 (which does not have an EEPROM).  You could possibly leverage that example.  One thing you'd have to change is using I2C instead of SPI.  See the CDCM6208 folder for more info.
