The Microchip ATMEGA48PA-MMH is a high-performance 8-bit AVR microcontroller in a compact 28-VFQFN package. It delivers 20MHz processing speed with 4KB flash and 512 bytes of SRAM. Operating from 1.8V to 5.5V, it integrates a brown-out detector, power-on reset, PWM channels, and a watchdog timer. Ideal for cost-sensitive embedded control applications requiring low power and small footprint.
- Wide voltage range (1.8V-5.5V): Simplifies power supply design and supports both 3.3V and 5V logic systems.
- 20MHz AVR core: Provides 20 MIPS throughput for real-time control tasks.
- Compact 28-VFQFN package: Saves PCB space while exposed pad improves thermal performance.
- Integrated safety features: Brown-out reset and watchdog timer enhance system reliability in harsh environments.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage allows direct operation from two AA batteries or a Li-ion cell, while the 20MHz speed enables fast wake-up and processing for periodic sensor readings.
Motor Control for Small Appliances
With built-in PWM channels and a 20MHz AVR core, this MCU can generate precise control signals for brushless DC or stepper motors in fans, pumps, and robotic toys.
Industrial Automation I/O Modules
The 28-VFQFN package with exposed pad aids thermal dissipation, and the wide voltage range tolerates noisy industrial supplies. The watchdog timer ensures reliable operation in remote I/O nodes.
Portable Medical Monitors
Low-power sleep modes combined with 512 bytes of RAM allow continuous monitoring of vital signs with minimal current draw, extending battery life in wearable patches.
Automotive Aftermarket Accessories
Operating from 1.8V to 5.5V and -40°C to 85°C, this MCU handles voltage transients in car power rails and can manage LED lighting or window control modules.
Smart Home Thermostats
The integrated brown-out detector prevents erratic behavior during power dips, while the 4KB flash is sufficient for PID control algorithms and user interface logic.
