Overview

The ATMEGA168PB-MUR is a high-performance 8-bit AVR RISC-based microcontroller featuring Functional Safety (FuSa) capabilities and 16KB of Flash memory. Operating at up to 20MHz, it integrates 1KB of RAM and 512B of EEPROM in a space-efficient 32-VFQFN package. This 'PB' variant is specifically enhanced with additional peripheral features and improved low-power performance compared to the standard 'P' series.

Why Choose This Part

This microcontroller combines a high-endurance memory architecture with an integrated 2-cycle multiplier and 27 I/O pins for efficient processing in a small 5x5mm footprint. Its comprehensive suite of sleep modes, including Power-save and Standby, allows for fine-tuned power management in energy-constrained designs.

Applications

Safety-Critical Industrial Controls
Leverages Functional Safety features to provide hardware-level reliability for industrial monitoring and shut-off systems.
Capacitive Touch Interfaces
Utilizes the built-in QTouch library support for implementing robust touch buttons, sliders, and wheels in consumer electronics.
Battery-Powered Remote Sensors
Takes advantage of a 1.54 uA sleep current and multiple power-saving modes to extend the life of compact, field-deployed wireless nodes.
