Problem with willem eprom programmer PCB45C + memory MX25L80

Сообщение Thulsa_Doom » Чт май 03, 2012 8:00 am

Hi my friends, I'm new in this forum and I have a problem with the programming of SPI memories.
I have a Willem eprom programmer PCB45C, purchased in sivava.
The software I have is the (0.98D12), downloaded it in this page web.
I want to program the memory, MX25L8005M2C and i can't

I think to program this memory I have to get the jumper is at the top next to the socket PLCC32 to go from 5V to 3V6.

I'm connecting the memory with an adapter SOIC8 - DIP and I'm connecting it at the green 40 pin socket.

The program did not recognize the chip, no read or write.
Anyone can help me?

sorry my poor english

¡¡PERFECT!!, works fine, thanks for your help.
the 3V6 jumper which is above the PLCC32 socket does nothing.
I had to feed the willem with 4v5.

It is necessary to have 3.6V Vcc for SPI chips in 25Cxx socket. You can damage chip with 5V or results not reliable. More supported chips find in latest SW 0.98d12c3, not HW fix related.
