Overview

The ATTINY814-SSF is an 8-bit AVR microcontroller featuring 8KB of Flash and a hardware multiplier in a compact 14-pin SOIC package. Part of the tinyAVR 1 series, it is specifically designed for Functional Safety (FuSa) applications and includes integrated features for capacitive touch and Core Independent Peripherals.

Why Choose This Part

This MCU offers high-performance throughput with its internal hardware multiplier and Event System, which allows peripherals to communicate without CPU intervention. The integration of a 10-channel ADC, DAC, and specialized capacitive touch hardware makes it highly versatile for mixed-signal designs in a small footprint.

Applications

Safety-Critical Industrial Controls
Utilizes integrated Functional Safety features and hardware CRC for monitoring system integrity in industrial environments.
Capacitive Touch Interfaces
Leverages the Peripheral Touch Controller (PTC) with Driven Shield+ technology for robust button, slider, and wheel interfaces.
Small Appliance Control
Provides a compact solution for managing motor control or user interfaces in household devices with minimal external components.
Distributed Sensor Nodes
Serves as an intelligent node in LINbus or UART-based networks using the internal Event System to reduce CPU overhead.
