Product Overview

The ATMEGA328-PU 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 ATMEGA328-PU achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
  • 131 powerful instructions – Most Single Clock Cycle Execution
  • 32 x 8 general purpose working registers
  • Fully static operation
  • Up to 20MIPS throughput at 20MHz
  • On-chip 2-cycle multiplier
  • Write/erase cycles: 10,000 flash/100,000 EEPROM
  • Optional boot code section with independent lock bits
  • In system programming by on chip boot program
  • True read while write operation
  • Programming lock for software security
  • Atmel® QTouch® library support
  • Capacitive touch buttons, sliders and wheels
  • QTouch and QMatrix® acquisition
  • Up to 64 sense channels
  • Two 8-bit timer/counters with separate prescaler and compare mode
  • One 16-bit timer/counter with separate prescaler, compare mode, and capture mode
  • Real time counter with separate oscillator
  • Six PWM channels
  • Programmable serial USART
  • Master/Slave SPI
