The Microchip ATTINY441-MMHR is a high-performance 8-bit AVR microcontroller in a compact 20-VFQFN package. It operates from 1.7V to 5.5V and runs at up to 16MHz, delivering efficient processing for control and sensing tasks. With 4KB of flash memory and 256 bytes of SRAM, it is well-suited for applications requiring moderate code space and low pin count. Its PWM capability and industrial temperature range make it a versatile choice for embedded designs.
- Wide Voltage Range (1.7V-5.5V): Enables direct battery operation and simplifies power supply design.
- Compact 20-VFQFN Package: Saves board space for miniaturized products.
- 16MHz AVR Core: Provides ample processing power for real-time control loops.
- Industrial Temperature Range (-40°C to 85°C): Reliable in harsh environments.
- Integrated PWM: Reduces external components for motor and lighting control.
Battery-Powered Sensor Nodes
The 1.7V minimum supply voltage allows direct operation from a single alkaline cell, while the 16MHz AVR core efficiently processes sensor data. Its low-power sleep modes extend battery life in IoT edge devices.
PWM Motor Control
With built-in PWM channels, the ATTINY441-MMHR can generate precise control signals for small DC motors or LED dimming. The 20-pin package provides enough I/O for feedback sensors and driver enable lines.
Portable Instrumentation
The 4KB flash and 256 bytes of SRAM are sufficient for calibration tables and measurement routines. Its wide voltage range ensures stable operation as batteries discharge.
Automotive Interior Lighting
Operating from 1.7V to 5.5V, it can interface directly with vehicle power rails. The -40°C to 85°C range covers cabin environments, and PWM outputs drive LED strings with smooth dimming.
Industrial Sensor Interfaces
The AVR core with 16MHz speed can handle protocol decoding (e.g., 1-Wire, I2C) while managing signal conditioning. The exposed pad aids thermal dissipation in enclosed enclosures.
Consumer Appliances
From coffee makers to smart plugs, the ATTINY441-MMHR provides cost-effective control logic. Its small footprint and robust I/O structure simplify PCB layout for high-volume production.
