Overview

The ATMEGA808-XF is an 8-bit AVR microcontroller featuring the megaAVR 0-series core with integrated Functional Safety (FuSa) features. Operating at up to 20MHz, it provides 8KB of Flash and 1KB of SRAM in a 28-pin SSOP package, optimized for high-reliability control applications.

Why Choose This Part

This MCU features a hardware multiplier and an Event System that allows peripherals to communicate without CPU intervention, reducing power and latency. It also includes an internal 20MHz oscillator and a Single-pin Unified Program Debug Interface (UPDI) to simplify board routing and reduce pin count requirements.

Applications

Industrial Safety Controllers
Utilizes integrated hardware safety features for monitoring and responding to critical system faults in factory environments.
Smart Home Appliances
Manages user interfaces and motor control logic while maintaining low power consumption in standby modes.
Sensor Hubs
Aggregates data from multiple I2C and SPI sensors using the Event System to reduce CPU overhead and latency.
