The Microchip ATMEGA48-20MMU is an 8-bit AVR microcontroller running at 20MHz. It features 4KB flash and 512 bytes RAM, operating from 2.7V to 5.5V. The 28-VFQFN package includes brown-out detection, POR, PWM, and WDT, making it a compact solution for cost-sensitive applications.
- 20MHz AVR core – provides fast execution for time-critical tasks.
- Low pin count (28) – simplifies PCB layout and reduces cost.
- Integrated brown-out detection – prevents data corruption during power dips.
- Wide voltage range – compatible with 3.3V and 5V logic.
Consumer Electronics
4KB flash is sufficient for simple remote controls or toy controllers, with 20MHz speed for responsive input handling.
Sensor Calibration Modules
The 28-pin package and PWM outputs allow precise trimming of analog sensor circuits.
Battery Management
2.7V-5.5V range supports monitoring of 3-cell alkaline or single Li-ion packs.
LED Lighting Drivers
PWM channels and WDT ensure stable dimming control in smart bulbs.
Small Appliances
Brown-out reset protects firmware in blenders or coffee makers during voltage dips.
Educational Kits
Simple AVR architecture and low cost make it ideal for learning embedded systems.
