A comprehensive list of all other members of the megaAVR series can be found on the Atmel website. Features ParameterĪ common alternative to the ATmega328 is the 'picoPower' ATmega328P.
The device achieves throughput approaching 1 MIPS/MHz. The device operates between 1.8 and 5.5 volts. The Atmel 8-bit AVR RISC-based microcontroller combines 32 KB ISP flash memory with read-while-write capabilities, 1 KB EEPROM, 2 KB SRAM, 23 general-purpose I/O lines, 32 general-purpose working registers, 3 flexible timer/ counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, 6-channel 10-bit A/D converter (8 channels in TQFP and QFN/ MLF packages), programmable watchdog timer with internal oscillator, and 5 software-selectable power-saving modes. It has a modified Harvard architecture 8-bit RISC processor core. The ATmega328 is a single- chip microcontroller created by Atmel in the megaAVR family (later Microchip Technology acquired Atmel in 2016). 8-bit microcontroller ATmega328P in 28-pin narrow dual in-line package ( DIP-28N) ATmega328P in 32-pin thin quad flat pack ( TQFP-32) Die of ATmega328P
