Overview

The ATTINY45-20SUR is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 4KB of flash memory and 256 bytes of SRAM. Operating at speeds up to 20MHz, this compact 8-pin SOIC device integrates essential peripherals like a high-speed PWM and a 10-bit ADC into a small footprint.

Why Choose This Part

The device offers a high power-to-size ratio with 32 general-purpose registers and 120 powerful instructions in an 8-pin package. It supports self-programming flash and includes a dedicated debugWIRE system for real-time on-chip debugging without consuming multiple I/O pins.

Applications

Compact Sensor Nodes
Utilizes the 10-bit ADC and internal temperature measurement for localized environmental monitoring.
Simple Motor Control
Leverages the programmable dead time generator and high-speed PWM for driving small DC motors or H-bridge circuits.
Safety Monitoring
Employs the programmable watchdog timer and brown-out detection for basic functional safety tasks in industrial or consumer hardware.
