Before program it, please erase the chip more than 40 minutes. And tell us the version of software and firmware you used.

i"m using the lastest software 4.5.1 and firmware 18.0

i erased it for more than 40mn too

EDIT:

so,
i have 10 ST M27C322,all fully UV erased

Everytime i want to program one,i check it by using the blank test,then read and looking at the buffer,all is full of "FF"

then i"m running the auto programm & got this

">>Man.Code:20  Dev. Code:34
>>.Auto Program......
>>.Blank Check......
>>.Program......
>>Device Address:00004000H Device Data:0200H Buffer Data:2F00H
>>Auto Program fail!
>> 11,23Sec"

Please help me,thanks

My system is Windows 7 64bits
