The Microchip ATMEGA48PA-MUR is a compact 8-bit AVR MCU with 4KB flash and 512B SRAM. Operating at 20MHz, it provides essential peripherals like PWM and brown-out detection. In a 32-VFQFN package, it supports 1.8V to 5.5V, making it a cost-effective choice for simple control applications.
- Cost-optimized: Lower flash size reduces unit cost for high-volume applications.
- Pin-compatible with ATMEGA88A: Allows easy firmware/hardware upgrades without redesign.
- Fast wake-up: Quickly resumes from sleep, ideal for intermittent sensing.
- Wide voltage range: Works with both 3.3V and 5V logic systems.
Cost-Effective Motor Drivers
With 4KB flash and PWM, it can control small DC motors in toys or pumps, reducing system cost.
Battery Management
Its low-power sleep modes and brown-out detection make it suitable for monitoring battery voltage in portable electronics.
Simple Sensor Nodes
It can read analog sensors and transmit data over UART or I2C in low-data-rate wireless sensor networks.
Lighting Systems
PWM outputs allow for dimming and color control in architectural lighting fixtures.
Security Systems
It can handle keypad scanning and alarm logic in simple access control panels.
White Goods
Reliable operation from 1.8V to 5.5V makes it ideal for washing machine timers or dishwasher control boards.
