hi EZO
thank for your programmer
i newly asebel the programmer i want to progeramm sst 39vf160
by: 4v5 0.98d and tsop-48_d2 jp-2 jp-5 jp-b but i can't .
in my first try i can read from chip but i was blanket az i now ( new chip).
then i check to wirt some thing but i can the error was :
error at 0x000000 chip=0xFFFF buffer=3330
then i check the jp and set them back to normalthen i can get id but that was 0x0000 0x0000
then i chenge the jp-2 and try agen then i can get the 0x2525 0x2525
and the error was :
error at 0x000000 chip=0x0500 buffer=3330
i need help about this problem would you plase tell what should i do?
thanks alot

Check programmer all signals in Test H/W mode. Read in guides section.

maybe your chip is damage
i program this chip

Hi I've Trying to program this chip since last post!!! but no success!
I still get the error :

I can read the chip which all of data blocks is 0xFF and even I can program 0xFF to chip, but when I try to program any other data Like 0x00 at any address it doesn't work and I face the error I mentioned above.

I Think the problem is in the target supply voltage which is 1.6V (Pin No. 20) but it should be 2.7~3.6 V as is written in the datasheet of Flash.

The V2 Transistor base and emitter voltage are the same. is this ok?

Check programmer in test H/W mode. Follow guides section and check info and pictures.

Follow schematic 5V 7805 output, each next diod with opened jumper reduce voltage ~0.7V.
Opened (for example Test h/W, tick 32-Vcc) pnp transistor base and emitter voltage are the same. Less voltage - wrong diod polarity, short in Vcc line (for example , check IC position , one 4015 opposite)
