Hello,

 I have a CY8C21323 24-Pin PSOC installed on a board I am trying to retrieve the binary code off of. It has a 7 pin breakout ribbon that connects to the psoc. The 7 pins really are only 5 unique pins as the last 4 pins are two groups, one connecting to GND and the other to POS. The remaining 3 pins connect to P1[1}, P1[0], and P0[2].

What PSOC programmer I should use for such an old device? Also, how do i connect it to the breakout ribbion?

 

Thank you

Hello @jon727 ,

You may use a CY8CKIT-002 to read the program off the CY8C21323. In case the original manufacturer has securely locked against reading the flash, you will not be able to read it. I request you to kindly give it a serious thought before purchasing the aforementioned kit to read the program flashed into the chip.

As for connections to the ribbon cable, I would be able to tell you better if you can show us a picture of the board and the cable connector.

Best regards,
