ATmega328

8-bit AVR Microcontrollers ATmega328/P DATASHEET COMPLETE Introduction The Atmel® picoPower® ATmega328/P 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/P achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed. Feature High Performance, Low Power Atmel®AVR® 8-Bit Microcontroller Family Advanced RISC Architecture – 131 Powerful Instructions – Most Single Clock Cycle Execution – 32 x 8 General Purpose Working Registers – Fully Static Operation – Up to 20 MIPS Throughput at 20MHz – On-chip 2-cycle Multiplier High Endurance Non-volatile Memory Segments – 32KBytes of In-System Self-Programmable Flash program Memory – 1KBytes EEPROM – 2KBytes Internal SRAM – Write/Erase Cycles: 10,000 Flash/100,000 EEPROM – Data Retention: 20 years at 85°C/100 years at 25°C(1) – 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 Atmel-42735A-ATmega328/P_Datasheet_Complete-06/2016 Peripheral Features – Two 8-bit Timer/Counters with Separate Prescaler and Compare Mode – One 16-bit Timer/Counter with Separate Prescaler, Compare Mode, ...
