AsProgrammer is a portable application, meaning it does not require installation—just run the executable.
Hardware technicians, builders, and cybersecurity researchers rely heavily on AsProgrammer 2.1.0.13 to recover corrupted computer motherboards, flash laptop graphics cards, and dump firmware for security analysis. Key Technical Enhancements in Version 2.1.0.13
While built for the CH341A , it supports other hardware like Bus Pirate , UsbAsp, and Arduino-based programmers.
: While primarily used with the CH341A, it also supports USBASP, Arduino-based programmers, and the Bus Pirate . asprogrammer+21013
AsProgrammer is a software tool, developed in Pascal/Lazarus, designed to program memory chips using various protocols, primarily via USB-to-SPI/I2C/UART converters. Originally designed for CH341A, modern versions now support: CH341 (SPI/I2C/UART) UsbAsp (requires firmware update) AvrIsp-mkII (requires firmware update)
AsProgrammer 2.1.0.13 is a specialized, open-source utility designed for flashing and programming 24-series EEPROM and 25-series SPI Flash memory chips, commonly utilized for BIOS recovery and firmware customization alongside CH341A USB programmers. This stable release version, often recommended within community forums for its reliability, supports functions such as reading, erasing, writing, and verifying chip contents, along with automatic ID detection.

Pin 1 is indicated by a dot or notch on the IC. On the CH341A adapter board, pin 1 must align with the notch on the socket. Step-by-Step: Programming a BIOS Chip
: If the chip is write-protected, use the "Unlock" or "Unprotect" function. Erase IC : Clear the existing data from the chip. Program IC : Write the new data to the chip.
: The ambiguous "S Register" column has been renamed to Status Registers , making it clearer for beginners modifying chip protection bits. AsProgrammer is a portable application, meaning it does
If you are using a black PCB CH341A, verify if it outputs 5V on data lines. It is often recommended to perform a 3.3V volt mod to avoid damaging modern BIOS chips.
For each supported chip, ASProgrammer provides a complete suite of operations:
"asprogrammer+21013" represents a reliable, robust version of one of the most user-friendly programming tools available. With its automatic chip detection, one-click programming, and critical file-conversion fixes, it is an essential utility for anyone working with SPI Flash or EEPROMs. While its community versions continue to evolve, the core logic and stability of version 2.1.0.13 define its enduring value in the world of hardware programming. : While primarily used with the CH341A, it
