FWIW, there's nothing similar in the 1992 Philips "Concise Catalog", but there are about 50 PCFxxx parts (none in a PLCC-44). Best regards, Spehro Pefhany -- "it's the network..."

PCF84C633A was a 8048 core with 64-segment LCD driver on-chip. I see PCAxxx and PCD3347. Best regards, Spehro Pefhany -- "it's the network..."

Thanks for all the replies and suggestions. I don't know how
far he got, may be he has fixed the device already. He sent me
also this a day or two ago (and I forgot to post it):

"The instrument is a Hartmann&Braun O2/CO2 meter  URAS10E.
A VFC output is connented to pin 6. Pin 13 seems to be  serial I/O.
Pin 14 seems to be clock for the serial transfer.
Other pins looks to be parallel ports."

What frequency is the crystal, what is connected to the PLCC44, and what does the Board actually do ? IIRC Philips did make PCF33xx series uC which used their 8048 core,and they may have done some emulation style parts in PLCC44 -jg

Could it perhaps be the PCD4500???? (Sometimes we see what we expect to see) http://www.micromech.co.uk/dir_products/nippon/ motion_control_chips_pcd4500.shtml http://www.npmchina.com/upfile/Uploadpictures/pcd4500_eng.pdf *Peter*

We had a large set of Philips databooks in the 90's, with regular updates. Unfortunately, almost all have gone now. But I did find IC25 from 1996. It's for the "16-bit 80C51XA Microcontrollers". In the intro section, there are the telephone numbers for the Bulletin Boards and Fax-on-Demand service, no web address. ;-) And it starts with an overview of all (? can't be sure it's complete) Philips microcontrollers at that time: 80C51 Family CMOS: 80Cxx, 83Cxx, 87Cxx 80CLXXX Family CMOS: 80CLxx, 83CLxx, 85CLxx 8051 Family NMOS: 8051, 8031, 8052, 8032 8400 Family CMOS: 84Cxx 8400 Family NMOS: 84xx 3300 Family CMOS: 33xx 16-bit controllers (68000 architecture): 68070, 93C101, 90CE201 16-bit controllers (XA architecture): XA-G1, XA-G2, XA-G3 Nothing with PCF numbers in there. What I rememeber from that time is that most PFCxxxx chips where (I2C) peripheral chips. -- Stef (remove caps, dashes and .invalid from e-mail address to reply by mail) Trouble always comes at the wrong time.

The MC14500B seems the best guess so far (I did not know the 14500). He'll probably see the discussion tomorrow (I sent him a link to it on google groups). While I can imagine someone could put that in a plcc in the late 80-s or early 90-s I could not find any reference to such a thing (spent perhaps 15 minutes searching). Thanks, Dimiter

Philips had a range of 8051 clones at about that era, but I can't seem to find an 8051 pinout with the crystal in that place. And I think they were numbered xx51. It isn't some wierd second-source of the MC14500B is it? Can't imagine why it would be in a 44 pin package. The other thing it could be is a Philips ASIC. Is it in a Philips instrument? Theo

Yep, same result (only I did not check any offers, I guess I am more tired from all those fake "suppliers" than you are :D ). Dimiter

I expect you already did a Google search and found the same thing I did, nothing. I see the number shows up on a site where you can try to get quotes, so they acknowledge that it existed and the time frame is right. It is not very often that a part goes so totally missing like this unless it was some sort of a custom part perhaps. But then maybe it disappeared from view before the Internet, so no trace left behind. -- Rick
