The Microchip ATTINY441-MMH is a low-power 8-bit AVR microcontroller in a compact 20-VFQFN package. It operates from 1.7V to 5.5V and runs at up to 16MHz, offering 4KB of Flash and 256 bytes of SRAM. With built-in PWM channels and a wide temperature range, it is designed for efficient control in space-limited, battery-operated applications.
- Ultra-low voltage operation (1.7V) – enables direct battery power without regulators, reducing system cost.
- Compact 20-VFQFN package – saves board space for miniaturized IoT and wearable designs.
- Integrated PWM – simplifies motor and lighting control without external timers.
- Wide temperature range (-40°C to 85°C) – ensures reliability in industrial environments.
Battery-Powered Sensor Nodes
The 1.7V minimum supply voltage allows direct operation from a single alkaline or Li-ion cell, while the 16MHz AVR core efficiently processes sensor data.
LED Dimming and Lighting Control
Integrated PWM channels enable smooth, flicker-free dimming with adjustable duty cycles, reducing external components and BOM cost.
Compact Motor Control
The 20-VFQFN package saves PCB space, while PWM outputs and the AVR core handle brushless DC motor commutation at up to 16MHz.
Portable Medical Monitors
Low-voltage operation and small footprint make it ideal for wearable health devices that require continuous monitoring with minimal power draw.
Industrial Automation I/O Modules
With a -40°C to 85°C temperature range, it reliably handles digital I/O and PWM control in factory floor environments.
Smart Home Controllers
Its 4KB Flash is sufficient for simple automation logic, while the exposed pad aids thermal dissipation in enclosed wall modules.
