Standard CH341A hardware outputs 5V logic or 3.3V power depending on internal configurations. If you attempt to interface with a modern low-power motherboard BIOS chip (such as 1.8V Winbond series), you run the risk of frying the memory controller. Ensure you utilize a dedicated between the CH341A and your chip to normalize signal boundaries. Hardware Unresponsive (All FF or 00 Readouts)
