how many times can a sst27sf512 chip be erased and burnt?

 

SST27SF512 256 Kbit - 512 Kbit - 1 Mbit - 2 Mbit (x Many-Time Programmable Flash Silicon Storage Technology

here is the data sheet, http://www.datasheetarchive.com/data...23/235612.html
but the short answer is yes

 

thats funny I didn't realize he was asking a yes or no question...

"How many times..."

But thanks for playing...

 

And your post helped him out how?? The answer in non yes or no is as many times as you want....there isnt really a limit

 

I've been using them for a year, and haven't had an issue with them shitting out on me.. :hrugs::

 

sweet, ive got two so thats all ill need then

 

i've got three chips

one is a 29c that has a known good map on it (the bbka track bin) in case something goes wrong and I need it. Better safe than sorry, I keep that one in my glovebox.

the other two are SST chips, I rotate them. Keep one in the ECU, one in the burner.

 

are all the chips that can be used in the willem burner pretty much the same, just have to switch the dip switches according to the chip

 

pretty much, the atmel 29c's (discontinued) dont have to be erased every time and no offset stuff has to be changed, etc...

 

If you make the power swtching daughterboard (plans are on PGMFI) you can put two programs on one chip, and literally switch between them.

..street tun.. race tune.. (On the 512K chips, that is..)
