39VF020 adapter prob. , pinout question , pics

By: Coffeetime - 2008-01-19 13:29:36

Hi,

I'am new to this forum and  want to program a 32VF020 with a willem pcb 4.5 from sivava.

I use the tsop32 to dip32 lowcost adapter.

Unfortunately I do not know what the Jumper on this adapter is for.

Does it connect vcc32 or gnd?

Because this, I'am unsure how to solder the chip on the adapter and accordingly how
to plug the adapter into the zif-sockel.

I attached some pictures and the pinout of the chip.

The stt missed a pin, it's just for example, also the adapter isn't as good as it should.

I've tried it several times in different direction but can't get a manufacture id.

I do have only one written chip left and want to ge 100percent sure I'am using it in the right direction.
Please, can someone tell me, how do I have to use this adapter?

Thanks in advance for your help.

Regards
Coffeetime

Hi,

I don't have that adapter and don't know what the jumper is for.  Trace the board.

From the pictures, it looks like you have the device soldered backwards.  If there's no pin 1 mark on the adapter, trace pin 16 or 32.  That will tell you how to orient the chip.

HTH,
Dennis

Hi Dennis,

thanks for your answer. By now I have to order a new adapter because I have to lift a pin up and broke it.

I allready looked on sivava, man I should do it first, and theire it is said the jumper is for 3,3v. So, am I right that pin 1 on the adapter connect Vcc. I am new to this so I'am not sure.
