Overview

The ATTINY212-SSF is a high-performance 8-bit AVR microcontroller featuring 2KB of Flash and 128 bytes of RAM in a compact 8-pin SOIC package. Part of the tinyAVR 1 series, it is designed for Functional Safety (FuSa) applications and utilizes Core Independent Peripherals to reduce CPU overhead in small-scale control tasks. Its single-pin UPDI interface simplifies programming and debugging without sacrificing multiple I/O lines.

Why Choose This Part

It offers an integrated hardware multiplier and Event System, which allows peripherals to interact directly without CPU intervention for faster response times. The wide operating voltage range up to 5.5V and 15mA I/O drive capability make it highly versatile for interfacing with various industrial and consumer electronics levels.

Applications

Functional Safety Controllers
Leverages built-in hardware CRC and watchdog timers for safety-critical monitoring in industrial environments.
Simple Sensor Nodes
Acts as an intelligent interface for analog or digital sensors using its internal 16MHz oscillator and I2C/SPI connectivity.
Logic Replacement
Replaces multiple discrete logic gates or small timing circuits with programmable logic in a minimal 8-pin footprint.
System Supervisors
Monitors voltage rails and system health using integrated Power-on Reset and Brown-out Detection.

Getting Started

Developers can use the Microchip Studio or MPLAB X IDE with the XC8 compiler to write code. Hardware programming is performed via the Unified Program and Debug Interface (UPDI), requiring a tool like the Atmel-ICE or the low-cost MPLAB PICkit 4. For rapid prototyping, the ATtiny212 is compatible with the Curiosity Nano development platform.
