Product Overview
ATMEGA328P-AU is a high-performance low power AVR 8bit microcontroller. It is a low power, CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. By executing instructions in a single clock cycle, the devices achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed.
- 131 powerful instructions – most single clock cycle execution
- 23 GPIO lines, 32 general purpose working registers, 3 flexible timer/counters with compare modes
- 20MHz frequency, 32KB program memory size, 2KB RAM, 1024bytes data EEPROM
- Internal and external interrupts, USART, an SPI serial port, a 6-channel 10-bit ADC
- Programmable watchdog timer with internal oscillator and five software selectable power saving modes
- Atmel® QTouch® library support
- Operates between 1.8-5.5V
- Industrial temperature range from-40°C to 85°C
- Available in 32 pin TQFP package
