Trying to read high-speed Winbond or Macronix 1.8V chips directly with a standard 5V/3.3V programmer line can corrupt or permanently damage the chip circuitry. You will need to place a hardware level shifter adapter socket between the CH341A board and your chip clip to safely drop the operational line voltage down to 1.8V.
The number often appears in community search queries related to chip libraries. This refers to the total number of distinct ICs the software now reliably supports. Through regular updates, the NeoProgrammer chip library has grown from ~1,629 IDs to over 2,103 chip definitions . This means the software can automatically detect and correctly configure nearly any modern SPI or I2C memory chip from manufacturers like Winbond, GigaDevice, Macronix, XTX, and many Chinese domestic brands found in routers and set‑top boxes. neo programmer 21019 download updated
As of 2026, the software is still actively maintained. Community developers have shifted focus to improving support (for modern Android TV boxes and high‑end routers) and streamlining the process of bypassing OTP (One‑Time Programmable) regions and ECC (Error Correction Code) zone calculations on NAND chips. The goal remains to keep the $5 CH341A competitive with professional $500 programmers.
