Overview

The ATTINY412-SSNR is a high-performance, low-power 8-bit microcontroller featuring the AVR architecture with 4KB Flash and 256B SRAM in a compact 8-SOIC package. Part of the tinyAVR 1 series, it includes functional safety (FuSa) features and a hardware multiplier to support robust industrial and consumer applications. With a maximum clock speed of 20MHz and an operating voltage range of 1.8V to 5.5V, it provides flexible power management for small-scale embedded designs.

Why Choose This Part

This MCU stands out for its high integration in an 8-pin footprint, offering a hardware multiplier and a sophisticated Event System that allows peripherals to communicate without waking the CPU. Its Functional Safety features, such as CRC and configuration change protection, make it suitable for mission-critical applications that typical 8-bit MCUs cannot handle.

Applications

Industrial Safety Sensors
Utilizes integrated CRC and functional safety features for reliable monitoring in industrial environments.
Battery-Powered Consumer Devices
Leverages 0.7uA standby current and flexible sleep modes to extend battery life in handheld electronics.
Smart Lighting Control
Uses the Configurable Custom Logic (CCL) and Event System to handle hardware-based logic without CPU intervention.
LIN Bus Nodes
Acts as a low-cost peripheral node in automotive or industrial networking via the USART LINbus support.
