Willem pcb50 jumper settings

[danyguit2000]

Hello,recently i have bought Willem pcb50,so far haven't used it...
I am about to read and write 27C512 eprom, but i am a bit confused with the jumper settings.
On the 27C512 datasheet says:

Table 6. Read Mode DC Characteristics (1)
(TA = 0 to 70 °C, –40 to 85 °C or –40 to 125 °C; VCC = 5V ± 5% or 5V ± 10%; VPP =VCC)

Table 8. Programming Mode DC Characteristics (1)
(TA = 25 °C; VCC = 6.25V ± 0.25V;VPP = 12.75V ± 0.25V)

Any idea what would be the jumper settings in this case?

What is full name of chip ? xx 27C512 xx ??

[danyguit2000]

It's Bosch: B58550 PLCC32

[Ezo]

Chip is not programmable , OTP - one time .
You can read only.

So have to get a blank one?
What would be the jumper's setting in my case then?

[Ezo]

All jumpers - normal. Vcc 5.6v. Dipswitch according picture in SW frame. Software mode pcb3b (for SW 0.97ja), pcb35 (for SW 0.98).External power supply.

Finally have got a new (blank) M27C512 PLCC32 Eprom and i am about to write it.
For programming mode i have set VCC=6.2V and VPP=12.75V (jumper settings)
When i did a test (external power supply) i get at VCC=6.39V and VPP=12.82V think it is ok... ?
My Willem is SIVAVA PCB50 and soft PCB50a(0.98D11)
Next question is what would be settings at the soft about Check Type 16bit Add, 32bit CRC, or blank and what about Skip Write 00xFF



Is there anything else important that i should know before Write it ???

Please help.

Can't write it, look at my video: http://www.youtube.com/watch?v=XSKpFjTjmQI

Your problem - PLCC socket is valid for chips 1-4Mb , where equal eproms are in DIP32 package.
For eproms 64-512kB external PLCC32-DIP28 adapter required.
Please mail me your used software installation package.

Hi Ezo,thanks for tryng to help,the software installation package is almost 600mb.What exactly you need from it so i email it to you.To be quite honest i wasn't sure whether this socket supports 27C512 PLCC32... I have tried 39SF020 into that socket and works perfectly (device ID,erese,read,write)...
Is there a schematic for dip28 to plcc32 (27C512) ?

[Ezo]

Here is no schematic on adapter. Get datasheet (like AM27C512) find PLCC32 and DIP 28 layout, equal signals are connected 1:1. 4pins from PLCC32 non-used.
Generic adapter layout here. If interess some other design for SMT socket are available.

Hi Ezo,you were right.... Just used DIP28 and PLCC32 and wired according to the datasheet of 27C512 and worked.Just to mantion that in PCB3b and SW 0.97ja mode failed...
The other funny thing that happened is during writting forgot to to remove the jumper for 5.0V and 6.2V ,so it worked even with 5.0V instead 6.2 .... i used M27C512
Thanks a lot for you help! It is much appreciated and you are a very helpful person...
Best regards.
