The ATTINY84-20MU is an 8-bit AVR microcontroller from Microchip (Atmel) offering 8KB flash and 512B RAM in a compact 20-WFQFN package. Operating at 20MHz with a 2.7V-5.5V supply, it integrates brown-out detection, POR, PWM, temperature sensor, and WDT for reliable embedded control.
- Ultra-low power consumption: 2.7V operation extends battery life in portable designs.
- Integrated temperature sensor: eliminates external sensing ICs, reducing BOM cost.
- Compact 20-WFQFN package: saves PCB space for space-constrained applications.
- Robust protection: brown-out reset and WDT ensure system stability in harsh environments.
Battery-Powered Sensor Nodes
Low 2.7V operation and brown-out detection ensure reliable operation in energy-harvesting or coin-cell designs.
Motor Control with PWM
On-chip PWM channels allow precise speed control for small DC or stepper motors.
Temperature Monitoring
Built-in temperature sensor simplifies thermal management without external components.
Industrial Automation
WDT and POR enhance robustness in noisy environments, ideal for relay control.
Portable Instruments
8KB flash and 512B RAM support compact firmware for handheld meters.
LED Lighting Systems
PWM outputs drive LED dimming with minimal external circuitry.
