Different Microcontroller Architectures

compare the performance and development workflows for other architectures

Cicely: Attiny45, Attiny44
Mohammed: Atmega328P, Atmega32u4

Talk about number of analog pins, digital pins, programming pins
Special requirements for each chip

Chips comparson :

so, for the group assignment we decided to compare the speed of two different chips to see how fast each can solve a differential equation using a benchmark test. The chips that we are going to compare are the atmega32p and the ATmega32U4 and they are basically an Arduino Uno and an Arduino Leonardo.

• This the benchmark code that we are going to be using:



• Atmega32p speed test:
• Atmega32up speed :
• Conclusion:

Attiny45 Data sheet :

• Reading 500 pages datasheet is nearly impossible so I focused on skimming through the graphs inside the data sheet and the first thing I saw was the attiny45 micro-controller. So this picture tells me that the attiny45 consists of 8-pins and each pin has a different job :
• The very next page of the this data sheet shows the pin description which I will need to know because I'll be using those pins to program my pcb::
• Another thing that got my attention while reading the datasheet is that these AVR micro-controllers has a sleep mode that enable the application to shut down unused module::
