Programming Times of the CY2XF33

Version 1
    Question: How many times is the CY2XF33 programmable?



    The CY2XF33 is a One Time Programmable (OTP) device and cannot be re-programmed after being programmed once.

    Part numbers beginning with CY2XF33FLX are field programmable devices.  They are unprogrammed when shipped.  The user may program them once, using a programmer such as the CY3675 CyClockMaker.

    Part numbers beginning with CY2XF33LX are factory programmed devices.  They are programmed by Cypress prior to shipping, and cannot be reprogrammed afterwards.
