How Mamy Programming Flash Memory Times of CY22381

[ericyu]

Hello,

 I notice that the non-volatility memory version of cy22381 , its max programing times of cy22381 is 100 ,in cy22381 datasheet, but when I program this part cy22381, it can be programmed only once, thus it can not be programed using a different pll output file( .jed), why? is it one time programing （OTP） part ? or/and there is any other part numbers of non-volatility memory version of cy22381 ?

thanks!

Hi @ericyu ,

The programming cycles also depend on the JEDEC file used for programming. If some of the bits in the JEDEC are  programmed to 0 then the part will not be reprogrammable. So the JEDEC you are using might be using setting those bits if you are unable to reprogram the device. 

Thanks,
