SPI Flash memory cannot overwrite data directly; it must be cleared to blank states ( FF ) first. Click the button (trash can icon).

Look for the small indented dot on your chip. This is Pin 1. Align it with the Pin 1 indicator on the ZIF socket (usually closest to the lever) or on your SOP8 test clip.

NeoProgrammer works seamlessly with specialized 1.8V adapters required for many SPI flash chips (e.g., Winbond W25Q series). NeoProgrammer is "portable," meaning it doesn't require a

Before connecting sensitive chips, verify if your programmer outputs 3.3V on the data pins (Pins 1–4 and 5–8). If it outputs 5V, consider performing the "CH341A 3.3V hardware mod" by bridging the voltage regulator pin to the VCC line, or buy a newer version of the hardware (like the green or pro versions) that fixes this design flaw.
