ATMEGA328-AUR, Microcontroller IC, AVR, 20MHz, 32 kB Flash, TQFP-32

ATMEGA328-AUR, Microcontroller IC, AVR, ATmega, 20MHz, 32 kB Flash, TQFP-32 Discontinued

This is Atmel’s high-performance, low-power 8-bit AVR ATMega328 microcontroller in a pint-sized TQFP package.
The high-performance Microchip 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory with read-while-write capabilities, 1KB EEPROM, 2KB SRAM, 23 general-purpose I/O lines, 32 general purpose working registers, three 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 five software selectable power saving modes. The device operates between 1.8-5.5 volts. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
