This software supports programming of Atmel microcontrollers 89Sxx ('51), ATtiny, ATmega and 90Sxx (AVR). It can erase built-in Flash and EEPROM memories as well as read and program them. ISP Programmer also supports serial Atmel DataFlash memories. Communication with devices is made serially in system (ISP - In-System Programming) without the need to pull the chip out of the socket or desolder it.
