: Neo Programmer supports an impressive range of chips, including SPI NOR flash, SPI NAND flash, SPI EEPROMs (25xxx, 95xxx series), I2C EEPROMs, MicroWire EEPROMs, AVR MCUs, Nuvoton MCUs, and many more. The chip database has been frequently updated over time, supporting over 2,000 different chips in later versions.

All‑zero (0xFF) data indicates either a bad connection (the chip isn’t communicating) or the chip has been erased and nothing has been written yet. Double‑check your wiring and voltage.

Always orient the target chip according to the layout silkscreened onto the CH341A PCB. Pin 1 (usually marked with a dot or dimple on the chip body) must align precisely with the locking lever orientation of the ZIF socket. 2. Auto-Detection

If you are into motherboards, BIOS modding, or fixing "bricked" electronics, you’ve likely encountered the limitations of standard software. Enter , a lightweight but incredibly powerful specialized tool designed for CH341A programmers.

: The software provides convenient read and write functions for FUSE bits and QE bits, which are critical for memory configuration and protection.
