: The software can automatically identify many 25-series SPI Flash chips by reading their internal ID, saving users from manual searching.
Don't just hit "Read." Use the Search button (the magnifying glass) to type in your chip's part number (e.g., W25Q64 ) to ensure the voltage and timings are correct.
Unlike basic tools, AsProgrammer 2.1.0.13 features clean labeling and access to the "Status Registers". This allows users to view, edit, or clear hardware write-protection bits ( S Registers ) which frequently block successful flashing on laptops and desktop motherboards.
The release of version 2.1.0.13 brought major architectural updates to the utility, changing how it handles safety, performance, and window configurations. Asprogrammer 2.1.0.13 Download
You can download the software from a variety of trusted third-party software archives:
If you get an error while writing, check the "SREG" (Status Register). Some chips are "Hardware Protected" and need their protection bits cleared within the software first.
: Capable of programming flash memory using SPI, I2C, and MicroWire protocols. : The software can automatically identify many 25-series
: The installation wizard will guide you through the process. Read each step carefully, and choose the options that best suit your needs. Be cautious of any pre-checked boxes that might offer to install additional software.
The software can identify the manufacturer and capacity of an unknown chip by probing the RDID (Read Identification) command.
Works well with standard CH341 serial/parallel drivers on Windows 10 and 11. This allows users to view, edit, or clear
