概要
Description
- 8KB Flash memory for program storage.
- 1KB SRAM and 512B EEPROM for data.
- 23 I/O pins, including ADC, PWM, and serial communication (UART, SPI, I2C).
- 16MHz max clock speed (internal or external oscillator).
- Low power consumption, suitable for embedded systems.
Housed in a 32-pin TQFP package, it’s ideal for prototyping and industrial applications. The ATmega8A-AU is widely used in automation, robotics, and DIY projects due to its balance of performance, cost, and ease of programming (via ISP or bootloader).
Key advantages include wide voltage range (2.7–5.5V) and robust peripherals, making it a versatile choice for beginners and professionals.
Features
