Product Description

ATMEGA328P-AU Product Information

Key Features

• Core: 8-bit AVR RISC architecture (131 instructions, most executed in a single clock cycle).

• Speed: Up to 20MHz (20 MIPS throughput).

• Memory:

  • 32KB Flash (16K × 16) with 10,000 write/erase cycles.

  • 1KB EEPROM (100,000 write/erase cycles).

  • 2KB SRAM.

• Voltage Range: 1.8V - 5.5V (supports low-power operation).

• Peripherals:

  • 6 PWM channels (for motor/servo control).

  • 8-channel 10-bit ADC (for analog sensor interfacing).

  • USART, SPI, I²C (for serial communication).

  • 3 timers/counters (two 8-bit, one 16-bit).

  • Programmable Watchdog Timer (WDT).

• Power Efficiency:

  • Active mode: 0.2mA @ 1MHz, 1.8V.

  • Power-down mode: 0.1µA.

• Package: 32-TQFP (7×7mm) (surface-mount).

• Operating Temperature: -40°C to +85°C (industrial-grade).

Applications

• Embedded Systems (custom PCB designs).

• Consumer Electronics (smart home devices, wearables).

• Industrial Automation (motor control, sensor interfacing).

• Automotive Electronics (basic control modules).

• IoT & Robotics (low-power sensor nodes).
