The ATMEGA48PA-MU is an 8-bit AVR microcontroller from Microchip Technology. It runs at 20MHz with a supply range of 1.8V to 5.5V. Featuring 4KB flash and 512B RAM, it includes PWM, WDT, and Brown-out Reset. The 32-VFQFN package offers a compact footprint for space-limited designs.
- Ultra-Low Voltage Operation (1.8V): Extends battery life in portable devices.
- High Integration: Includes PWM, WDT, and POR in a small QFN package.
- Fast 20MHz AVR Core: Provides efficient processing for real-time tasks.
- Wide Temperature Range: Reliable from -40°C to 85°C for general-purpose use.
Wearable Fitness Trackers
The 1.8V minimum supply voltage allows direct operation from a single lithium coin cell, reducing power conversion losses.
Small Robotics
With 512B RAM and PWM, it can control two servo motors and read ultrasonic sensors for obstacle avoidance.
Home Automation Sensors
Its low power consumption and WDT make it ideal for battery-powered door/window contact sensors.
LED Lighting Controllers
The 20MHz speed and PWM channels enable smooth color fading effects in RGB LED strips.
Data Loggers
4KB flash can store calibration constants and logging routines for environmental monitoring.
Educational Kits
Its simple AVR architecture and wide voltage range make it perfect for student prototyping boards.
