Chip replacment

Postby Lord Grezington » Thu May 11, 2017 11:38 am

Hello All

I have completed a design using the dsPIC33EP32MC504-I/PT (44 pin TQFP) and I am very pleased with the performance so far. However I now need to try and save some variables into the EEPROM... It turns out this IC does not have any EEPROM...

I know the options are to get an external EEPROM IC which is good, however I have just spent a load of money getting the prototypes made without the EEPROM IC and dont really want to change the whole design. The other option is to find an alternative that has the same Pin out and has EEPROM, the problem being is none of the IC's in the family have EEPROM and I cant seem to find any other one that is FC compatible and has the same Pin outs.

Does anyone else have any suggestions?

Thanks

You can write to flash and safe your variables to flash see the Family documentation.
It is done this way in many applications

Hello,

Have you seen this Flowcode 6/7 component from Kersing, it may do just what you are looking for with your current device.
