The ATTINY43U-MUR from Microchip Technology is an 8-bit AVR microcontroller operating at up to 8MHz. It features 4KB flash and 256 bytes RAM in a 20-WFQFN package. With a wide 1.8V-5.5V supply range, it integrates a temperature sensor, PWM, BOD, and WDT, making it a versatile choice for cost-sensitive embedded control.
- Wide voltage range: 1.8V-5.5V supports battery and 5V logic systems.
- Integrated temperature sensor: Eliminates external sensor for thermal monitoring.
- Low cost: Ideal for high-volume consumer products.
- Compact 20-WFQFN: Saves board space in miniaturized designs.
- Robust protection: BOD and WDT enhance system reliability.
Small Appliances
The 8-bit AVR core and 5.5V support make it ideal for controlling blenders or coffee makers with simple PWM motor control.
Battery Management
Low-power sleep modes and wide voltage range enable efficient battery voltage monitoring in portable electronics.
