I would like to present my little program "AVRdb" that contains a database with basic informations about all 8-bit AVR microcontrollers from the AT90, ATtiny, ATmega and ATxmega families. In addition, it presents arrangement and descriptions of fuse/lock bits that are available on selected chip.
Currently there are 354 models in database - including latest ATtiny/ATmega chips with UPDI interface. All informations come from datasheets and definition files (XML/ATDF) of the AVR/Atmel Studio environment. I wrote the program in C language using free "Open Watcom 1.9" IDE. Requirements: Windows 95+, CPU 386+.
