I removed this chip with markings "14 8A SA4" between an HDMI port and a USB port that was faulty. I need to replace it, but I have not been able to properly identify this chip using the markings provided on the chip itself. If anyone is able to provide information regarding this chip, I would greatly appreciate it.

Hi
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).
The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.
I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6... -
On a Gigabyte B660M DS3H AX I found a chip with a crater. I was not able to find a boardview/schematic of this board.
I have a hard time identifying it, so maybe you would be so kind to help me out.
It the first two symbols are most probably N3, followed by DPC.
Already thanks for your attention. -
