Q: What are the key features of the Neo Programmer 21019? A: The Neo Programmer 21019 features multi-protocol support, multi-device support, high-speed programming, a user-friendly interface, and a compact design.
SPI F-RAMs, FRAMs, and MicroWire EEPROMs (93Cxx 8/16 bit, 93C57).
Thanks to its regularly updated chip database, NeoProgrammer can recognize and correctly program thousands of memory chips, including newer SPI NAND devices from manufacturers like SkyHigh, XTX, BoyaMicro, Fudan, and Macronix. As of February 2026, the database includes — a massive improvement over the 1500–1600 chips supported in earlier versions. neo programmer 21019 free upd

, specifically optimized for the CH341A USB programmer to read, write, and erase SPI flash and I2C EEPROM chips. Update History Version 2.1.0.19
The “free upd” part is important: unlike some commercial programming suites that charge for upgrades, NeoProgrammer is . There is no paywall, no limited trial period, and no hidden fees. You can download the latest version and use it for any purpose, including commercial repair work, without any cost. SPI F-RAMs, FRAMs, and MicroWire EEPROMs (93Cxx 8/16
Inside the extracted folder, locate the Drivers subdirectory. There should be a CH341A folder containing a SETUP.EXE file. Run this setup program to install the USB driver for your CH341A programmer. Important: If you are using Windows 10 or 11, you may need to temporarily disable driver signature enforcement or run the installer as administrator. Alternatively, you can use Zadig to install the libusb-win32 driver for the CH341A device.
The update adds support for numerous legacy EEPROMs and microcontrollers, including TC97101, TC89101/102, AK93C45A, AT90S1200, ATtiny12, and many others.
Many routers (e.g., from Xiaomi, ASUS, TP‑Link) store their firmware on SPI Flash chips. When a firmware update fails, the device becomes a “brick” — but with NeoProgrammer, you can directly write the correct firmware image to the flash memory, bypassing the bootloader entirely. : Uploading custom firmware to devices like routers
