Hi all. I'm looking into the Cypress EZ-USB AN2131 chips (yes, I know they aren't the latest). It's an enhanced 8051 core chip. I've looked at the datasheet at the Cypress website, and I can't seem to find any mention of code protection like the PICs have. Am I just not using the correct "Cypress" term for this, or can anyone download the firmware off of these chips and then program more?
