The Atmel ATTINY24-20SSUR is a compact 8-bit AVR MCU running at 20MHz. It offers 2KB flash and 128 bytes of RAM, operating from 2.7V to 5.5V. With brown-out detection, POR, PWM, temperature sensor, and WDT, it provides a complete solution for small embedded systems. The 14-SOIC package is easy to solder and widely available.
- Integrated temperature sensor: Eliminates external thermistor, saving cost and PCB space.
- 20MHz AVR core: High speed for its class, enabling fast response in control loops.
- Wide voltage range (2.7V-5.5V): Works with both 3.3V and 5V logic systems.
- 14-SOIC package: Industry-standard footprint, easy for prototyping and mass production.
Small Motor Controllers
The 20MHz AVR core and PWM channels drive brushed DC motors in toys and small pumps.
Temperature Monitoring
Built-in temp sensor and 2KB flash enable threshold-based alerts in HVAC systems.
Battery Chargers
2.7V-5.5V range and brown-out detection manage charge cycles for NiMH or Li-ion cells.
LED String Lights
PWM outputs create color effects with minimal external components.
Security Sensors
WDT and low power modes support battery-operated PIR motion detectors.
Analog Data Acquisition
128B RAM buffers ADC samples for simple data logging in agricultural sensors.
