The ATMEGA88A-MU from Microchip Technology is a high-performance 8-bit AVR microcontroller in a compact 32-VFQFN package. It operates from 1.8V to 5.5V and runs at up to 20MHz, delivering efficient processing for cost-sensitive embedded designs. With 8KB of flash memory, 1KB of SRAM, and a rich set of peripherals including PWM, analog comparator, and brown-out detection, this MCU is ideal for industrial control, consumer electronics, and automotive applications.
- Wide voltage range (1.8V-5.5V): Enables flexible power supply design, from single-cell batteries to regulated 5V rails.
- High integration: Includes POR, BOD, PWM, and WDT on-chip, reducing external component count and BOM cost.
- Compact QFN package: The 32-VFQFN with exposed pad improves thermal performance and minimizes PCB footprint.
- Proven AVR architecture: Industry-standard instruction set with extensive toolchain support for rapid development.
Industrial Sensor Nodes
The 1.8V minimum supply and multiple sleep modes enable low-power operation for remote industrial sensors monitoring temperature or pressure over long durations.
Automotive Body Electronics
With a 5.5V maximum supply and robust I/O, it can interface directly with automotive-grade 5V logic and handle window lift or mirror control modules.
Portable Medical Devices
The 8KB flash and 1KB SRAM are sufficient for simple glucose meters or pulse oximeters, while the wide voltage range supports single-cell battery operation.
Smart Home Controllers
Its PWM channels and 20MHz speed allow precise dimming control for LED lighting and motorized blinds, with the QFN package saving board space.
Data Logging Systems
The built-in EEPROM and brown-out detection ensure reliable data retention and reset behavior in logging applications for environmental monitoring.
Motor Control for Drones
The 20MHz AVR core and fast ADC enable real-time feedback loops for small brushless DC motor controllers in hobbyist drones.
