PSoC 5, 3 & 1 MCU

Hello everyone,

   

Could you please tell me which memory saves the program loaded from PC in PSoC 5LP Development board? 

   

Because after I load my program through usb, the program is still on board when I use the board next time. It seems that the program is stored in a ROM.  I checked that development kit has FX2LP which also has EEPROM like PSoC chip. Is the memory in FX2LP or in PSoC chip? I'm confused about the programming process. It would be great if you could tell me a little about how the program is loaded? Thanks a lot!

All PSoCs have got flash memory on chip which can be erased and re-programmed. Flash keeps it information when power is removed, just like an USB memory-stick. Flash can be programmed 100K times which is usually less than EEProm is capable of.

 Hello Bob, 

   

Thank you!  That makes sense.  So the code from PC is loaded by FX2LP via USB and stored into flash memory on PSoC chip. Am I right?

   

Best,

Yes, that's right. The FX2-chip builds the USB interface to the PC and the programming and debugging interface to the PSoC5LP.

   

The programming of the FX2 is usually not changed, only the PSoC's flash gets updated with a new project.
