[MBAVR-1] Minimalist development board for MCU of tinyAVR family (i.e. ATtiny13, ATtiny85, etc.)

This is a quick how-to guide of making a minimalist development boards for MCU of tinyAVR family like ATiny13/25/45/85. The idea behind this project was to create an environment for rapid development. I’ve been designing many projects based on this little MCUs and I didn’t want to wire it all up any more by hand. … Read more

AVR MCU Architecture

The AVR architecture is a huge topic in itself. I will just provide a general picture of how the AVR microcontroller works. The AVR uses a Harvard architecture thus it has separate memories and buses for program and data. Instructions in the program memory are executed with a single level pipelining. While one instruction is … Read more

What is an AVR Microcontroller ?

The AVR is a modified Harvard architecture 8-bit RISC single-chip microcontroller. The AVR was developed by Atmel in 1996 and was one of the first microcontroller families to use on-chip flash memory for program storage. The AVR microcontoller is like a small computer – includes a CPU, some flash program memory, some SRAM and some … Read more
