Description
Key highlights:
- Clock speed: Up to 20MHz.
- Peripherals: 12-bit ADC, USART, SPI, I²C, and multiple timers.
- GPIO: 28 programmable I/O pins.
- Low-power modes: Ideal for battery-operated devices.
- Package: 32-pin TQFP (AU suffix).
It supports Core Independent Peripherals (CIPs), reducing CPU load, and is programmable via UPDI (Unified Program and Debug Interface). The ATmega808-AU is commonly used in automation, IoT, and consumer electronics.
For development, Microchip provides MPLAB® X IDE and Atmel Studio support. Its balance of performance, power efficiency, and integration makes it a versatile choice for cost-sensitive designs.
Equivalent
- ATMEGA808-MU (QFN package variant).
- ATMEGA809-AU (similar specs, more flash).
- ATMEGA1608/1609 (higher memory variants).
- ATTINY817 (lower-cost alternative, fewer features).
These are pin-compatible or functionally similar alternatives within Microchip's 8-bit AVR lineup. For exact replacements, verify datasheets for specific requirements.
Application
- Embedded Systems: IoT devices, sensors, and automation.
- Consumer Electronics: Smart home gadgets, remote controls.
- Industrial Control: Motor control, monitoring systems.
- Automotive: Basic control units, lighting systems.
- DIY & Hobby Projects: Arduino-compatible applications.
It features 8KB Flash, 1KB SRAM, 12 I/O pins, and supports UART, SPI, I²C, making it suitable for cost-sensitive, low-power applications.
