The Microchip ATTINY24-20MU is a low-power 8-bit AVR microcontroller with 2KB flash and 128 bytes SRAM. It operates from 2.7V to 5.5V at up to 20MHz, featuring a 10-bit ADC, internal temperature sensor, and multiple PWM channels. The 20-WFQFN package (4x4mm) is ideal for miniaturized designs in consumer, automotive, and industrial applications.
- Ultra-Compact Package: 20-WFQFN (4x4mm) saves PCB area for space-limited products.
- Integrated Temperature Sensor: Eliminates external thermistors, reducing BOM and calibration effort.
- Low Power Consumption: Multiple sleep modes and 2.7V operation extend battery life in portable devices.
- Fast 20MHz Clock: Provides quick response for real-time control loops despite small memory.
Compact LED Lighting Controllers
The 2KB flash and PWM channels enable smooth dimming and color mixing in small form-factor LED drivers, with the 20MHz clock handling fast PWM updates.
Battery Management in Wearables
With a 2.7V minimum supply and low-power sleep modes, this MCU monitors battery voltage and temperature in fitness trackers, extending operational life.
Small Motor Control (Drones)
The integrated PWM and ADC allow precise speed control of micro DC motors in mini drones, while the small package saves critical board space.
Sensor Signal Conditioning
Its 10-bit ADC and internal temperature sensor make it ideal for calibrating and linearizing analog sensors in industrial probes.
Automotive Interior Lighting
Operating up to 85°C, it reliably controls ambient lighting strips in car cabins, with the watchdog timer ensuring fail-safe operation.
Consumer Appliance Timers
The built-in WDT and brown-out detection provide robust timing functions for microwave ovens or coffee makers, reducing external supervision circuitry.
