Figure 1-2.
Pinout ATmega329P
Note:
The large center pad underneath the QFN/MLF packages is made of metal and internally con-
nected to GND. It should be soldered or glued to the board to ensure good mechanical stability. If
the center pad is left unconnected, the package might loosen from the board.

Disclaimer
Typical values contained in this datasheet are based on simulations and characterization of
other AVR microcontrollers manufactured on the same process technology. Min and Max values
will be available after the device is characterized.
2.
Overview
The ATmega329P/3290P is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By
executing powerful instructions in a single clock cycle, the ATmega329P/3290P achieves throughputs approaching 1 MIPS
per MHz allowing the system designer to optimize power consumption versus processing speed.
