Difference between ATMEGA328P-PU and ATMEGA16A-PU

Date: 14-07-2021 ClickCount: 7451

What is the difference between ATMEGA328P-PU (Arduino-URO main controller chip) and Atmega16A-PU

The biggest difference between ATMEGA328P-PU and Atmega16 is that their FLSAH capacity is different, the former is 32KB, the latter is 16KB, the number of external interrupts is also different, the rest is basically the same, ATMEGA series of microcontrollers are mainly different FLASH capacity, as well as to increase some function modules, essentially the same, assembly instructions are basically the same. The assembly instructions are basically the same, there is no substantial difference.

All are 40pin DIP package

And the Atmega16 can be burned into an Arduino compilable microcontroller by the following link
