Overview

The ATTINY816-MFR is an 8-bit AVR microcontroller featuring 8KB of Flash and 512 bytes of SRAM in a compact 20-pin VQFN package. Part of the tinyAVR 1 series, it is designed for functional safety (FuSa) applications and includes a hardware multiplier and an integrated Peripheral Touch Controller.

Why Choose This Part

This MCU provides high-performance peripheral control through its Event System, allowing peripherals to communicate without CPU intervention. It combines hardware-based safety features with advanced touch capabilities in a tiny 3x3mm footprint, making it ideal for space-constrained safety applications.

Applications

Safety-Critical Monitoring
Utilizes the built-in CRCSCAN and hardware safety features for monitoring system health in industrial environments.
Capacitive Touch Interfaces
Leverages the Peripheral Touch Controller (PTC) with Driven Shield+ technology for reliable buttons, sliders, and wheels.
Sensor Signal Conditioning
Uses the 12-channel ADC and Configurable Custom Logic (CCL) to process analog inputs without heavy CPU overhead.
Handheld Battery Devices
Optimized for low power consumption with a 4uA standby current and operating voltages down to 2.7V.
