Hi All, I've selected AT47LV1614A in the device list i have a TSOP 48 8/16 BIT adapator but i can't get it to erase the chip well funny thing is it gets to 1 percent says chip erased i read it it shows mostly FF'S but there are parts with data and blank check fails. Now i am NEWBIE i've got the 3X version of the WIllem the adaptor has got some jumpers on it J1 J2 2 of each 4 in total.
My question is software says set jumper to 5v how?? i dont see anything saying 5v only jumper on the adaptor states 3v6 open.
It reads and detects the chip fine i looked in the lock unlock section of the software and it shows
SA00 (0x000000 - 0x00ffff) is protected(0x01). *** SA01 (0x010000 - 0x01ffff) is protected(0x01). *** SA02 (0x020000 - 0x02ffff) is unprotected(0x00). SA03 (0x030000 - 0x03ffff) is unprotected(0x00).

i cant get it to unlock those protected areas do i need to connect address cables do i need to alter the j1 j2 jumpers please can someone explain to me step by step as i am newb as to what i need to do in order to erase and program this chip please?
i dont know how to set the jumper to 5v so any help appericated.
-Close the Vcc jumper for 5V. -When erasing and writing, click on Yes button when the software ask you to turn on the temporary unprotect feature. -Set J1 for 29FXXX. -You should be able to get the correct ID, if not, check the pin contact. Clean the pin if necessary.
ZLM THANKS!! :) buddy i have one last problem i have done as you have asked now all sections show unprotect which is good but it still has trouble erasing i set chip to AT47LV1614A it try to erase get to 1percent and says chip erased however blank checks fails each time. is there anything else i can do?
still no luck guys can't get it to pass blank check i have connected the address lines a19 a20 to board closed 5v jumper it reads the chip fine it says it has erased it fine to but fails blank check
Turn on the temporary unprotect feature when erasing and writing. Ths software will ask you if you want to turn on this feature when you start to erase and writing. Click on Yes button when the software ask you .
I had the same problem and if i did manage to get one to erase it would always fail in programming,gave up in the end and just use a standard willem now,programmer is very good for all other chips i use though
hi 1:use tsop48 8/16bit adapter 2:Turn on the temporary unprotect feature when erasing and writing your device 3:select AT49LV1614A device if error message and can not working try with 29lv160 device and then erase with Turn on the temporary unprotect feature good luck
already tried that guys i always turn on the temp unprotect feature it states it erases fine but fails the blank check when i try and re=read the chip it shows all FF's expect some parts have diffrent letters i persume the protected parts so it seems it's not unprotecting the chip even thou it states it is.
