what programmer for Winbond W25R256JW

[rumpumpel1]

Off topic, but I think I have the best chance to get an answer here: Which programmer can read a Winbond W25R256JW (not W25R256JV) ?

Hello,
REVELPROG-IS.

[rumpumpel1]

Thanks, have you tried it or is this information just based on datasheets?

[rumpumpel1]

really no one who has ever read such a chip?

Do you already have an SPI programmer, if so what model is it and the software version. Is the W25R256JW chip on a laptop motherboard or something else

I have RT809H and T56 with the latest Software.
The Laptop which is using this chip is a ThinkPad L13 Yoga Gen 4 (22302).

Looks like it's supported by the RT809H

WINBOND W25R256JW@WSON8 6X5
WINBOND W25R256JW(X4)@WSON8 6X5
WINBOND W25R256JW@WSON8 8X6
WINBOND W25R256JW(X4)@WSON8 8X6
WINBOND W25R256JW@SOIC16
WINBOND W25R256JW(X4)@SOIC16

EDIT: I don't know if you need 1.8v adapter, that chip is 1.8v

Not yet supported by the T56

Except an ID error I could not get any useful reading. I'm using a Pogo-Pin adapter, may be I have to desolder the chip.

Have you tried with latest software for RT809H (linked above at ifix website)?
Or from here:
https://www.hklrf.com/wap/Download.html?styleid=&page=2
Scroll down to "Latest version application software for RT809H programmer", dated 23/04/2025

Try both options
WINBOND W25R256JW@WSON8 8X6
WINBOND W25R256JW(X4)@WSON8 8X6

For the T56, I think the W25Q256JW is close enough, it may work

According to W25R256JW datasheet the device ID is the same EF 60 19

I installed the latest SW RT809HSE_20250423_ENG.exe and realized, that the SW-package seems to be faulty: the main exe file is missing. So I am now using RT809H_RT809HSE_20241125_ENG.exe.

yes, that worked.

[m1ch43lzm]

yes, that worked.

Noted, as I have T48 programmer
W25R256JW == W25Q256JW

Same should also work for W25R128JW, select W25Q128JW

Can confirm this, virustotal report:

4. If you encounter some anti-virus software that reports or prompts the programmer software, please rest assured to use it, and add trust and allow it to run!

Yeah, sure... It may be a false positive flagged by several AV vendors, likely whatever code protection/code obfuscation they use for the main .exe triggers those AV, they should work instead with those AV vendors and report it as false positive
