PHILLIPS PCF8594C-2 Reply

 Hello,

I have a problem with PHILLIPS PCF8594C-2 (512x8) using my VP-480, software version 4.2.0, 27 May 2009.

When I read the chip, the programmer only reads the lower half correctly, the upper half (100H-1FFH) is read as FFH.

When I try to program the chip, the lower half is programmed and verified Ok, the upper part is FFH and does not verify.

Please advise.

 I have just downloaded and installed Ver. 4.3.0 (22 Feb. 10) (ZIP file, not EXE) and I am getting the exact same error.

I have tested several chips, all chips were tested Ok on a different programmer (not Wellon), but they fail on my VP-480.

Regards,

D.

 It is the same error.

But I don"t understand how this can be a programmer problem.

To program PCF8594C 100-1FF its only bit #1 set to 1 for the address.
Its not a physical pin address.

I am writing/programming　lots of other chips (PIC, ATMEL, SPROM, EPROM) and I never had a problem with the programmer.

Did you successfully program a PCF8594C with all zero data with this software version?

Regards,

D.

 I can read/write 24C04 with no problem.

This is an identical chip, the only difference is the protocol for writing 100-1FF.

I think the programmer is Ok, and the problem is with the software used for PCF8594C.

Regards,

D.
