The programmer uses an AVR Atmega-8 microcontroller, three 74164 ICs and a handful of passive components. I need to program certain types of parts only (namely 4-MBit Flash RAMs), and wanted to use what I had handy, so the implementation reflects this. A Flash RAM programmer is going to be a necessity as the CFT project acquires speed, and I'd rather make my own tools than buy them at exorbitant prices. The article contains schematics and platform-independent software.Įveryone and their granny has a ‘zero-parts’ EPROM, EEPROM or Flash programmer design. ![]() Here's how to build your own fast USB/Serial-based EPROM/EEPROM/Flash programmer you have a spare Atmega microcontroller, FTDI cable or board and a few serial-in/parallel-out shift registers.
