Hello, I was wondering what is needed to reprogram the CY22393. It came programmed with the default serial address of 69H, but I need to change the address to something different for project use. I also have questions on the set up, reading back, it looks like I2C programming can only be used for volatile memory. Will i need to pick up a programmer to reprogram the serial address? Also, any tips and tricks to help me get started with reprogramming the CY22393 device would be greatly appreciated. i couldn't only find posts about this product and my specific issue unless they were from 2008-2009. so i wasnt sure how valid those post still were.
Thanks for the help.

Hi @msn47,

 

Regarding I2C programming, you are correct. It configures the volatile memory. And hence on every power cycle, you will lose those configurations.

> Could you please let us know the complete MPN of the part you are using?


Regarding reprogramming, please gives us some time to check and get back to you.



Thanks,

we need to program around 50 devices. Id also like the capability of reading the device back. What would be a few programmer options that we would be able to read and program these devices with?
id send the jedec file but its an unsupported file type and im unsure how to attach it.
