The Microchip ATTINY84A-PU is a low-power 8-bit AVR MCU in a 14-DIP package. It operates from 1.8V to 5.5V at up to 20MHz, with 8KB flash and 512B RAM. Integrated Brown-out Reset, POR, PWM, Temp Sensor, and WDT provide robust functionality. Ideal for hobbyist, educational, and industrial applications requiring simple, reliable control.
- DIP package enables easy breadboarding and through-hole soldering for prototyping.
- Wide voltage range (1.8V-5.5V) supports battery and 5V logic systems.
- Integrated temperature sensor adds monitoring capability without external parts.
- 20MHz speed is sufficient for most small control and sensing tasks.
Prototyping and Education
The DIP package is breadboard-friendly, making it perfect for learning embedded systems or rapid prototyping with 20MHz AVR performance.
Sensor Data Loggers
512B RAM and 8KB flash store calibration data and logs, while the temp sensor monitors environmental conditions.
Small Motor Controllers
PWM outputs and 5V operation drive small DC motors or servos in hobby robotics without external drivers.
Battery Management Systems
1.8V operation and brown-out detection ensure safe operation in single-cell Li-ion protection circuits.
Home Automation Sensors
Low power consumption and WDT make it reliable for door/window sensors reporting over RF links.
Analog Signal Processing
Built-in ADC and PWM enable simple closed-loop control for temperature or light regulation.
