What does p refer to in ATmega328p?

production
pico- power
power-pico
programmable on chip

The letter “p” in ATmega328p refers to “pico power”. This means that the microcontroller is designed to be very energy efficient, which is important for applications where battery life is a concern.

The other options are not correct. Option A, “production”, is not a meaningful abbreviation for a microcontroller. Option B, “pico-power”, is the correct answer, but it is not the only option. Option C, “power-pico”, is not a meaningful abbreviation for a microcontroller. Option D, “programmable on chip”, is not a meaningful abbreviation for a microcontroller.

Here is a brief explanation of each option:

  • Option A, “production”, is not a meaningful abbreviation for a microcontroller. Microcontrollers are typically not given abbreviations that refer to their production status.
  • Option B, “pico-power”, is the correct answer. The “p” in ATmega328p stands for “pico power”, which means that the microcontroller is designed to be very energy efficient.
  • Option C, “power-pico”, is not a meaningful abbreviation for a microcontroller. Microcontrollers are typically not given abbreviations that refer to their power consumption.
  • Option D, “programmable on chip”, is not a meaningful abbreviation for a microcontroller. Microcontrollers are typically not given abbreviations that refer to their programming capabilities.
