Overview

The ATTINY416-SNR is an 8-bit AVR microcontroller featuring 4KB of Flash and a 20MHz clock speed, specifically designed for functional safety and low-power applications. It integrates the tinyAVR 1 series architecture with advanced features like Configurable Custom Logic (CCL) and an Event System to reduce CPU overhead. The device operates across a wide 1.8V to 5.5V range, making it suitable for modern battery-powered and industrial systems.

Why Choose This Part

This MCU offers a hardware multiplier and 20MHz performance in a compact 20-SOIC package, providing significant processing power for its size. The integration of an Event System and CCL enables deterministic hardware-to-hardware communication, reducing power consumption and software complexity.

Applications

Functional Safety Controllers
Utilizes integrated hardware features and Configuration Change Protection to maintain system integrity in safety-critical industrial loops.
Battery-Powered Handhelds
Leverages 8uA standby current and 1.8V operation to extend life in portable consumer and medical devices.
Sensor Interface Nodes
Uses the 18 I/O pins and Event System to process sensor data without constant CPU intervention, ideal for low-latency responsiveness.
Hardware Logic Replacement
The Configurable Custom Logic (CCL) block allows the designer to implement simple glue logic or signal conditioning without external discrete components.
