The Microchip ATTINY25-20SSN is a compact 8-bit AVR microcontroller in an 8-pin SOIC package. It provides 2KB Flash, 128B SRAM, and runs at 20MHz. With a 10-bit ADC, two PWM channels, and an extended temperature range up to 105°C, it is designed for space-limited, high-temperature applications in automotive and industrial settings.
- Extended Temperature Range: -40°C to 105°C ensures reliable operation in engine bays or industrial ovens.
- High-Speed PWM: 20MHz operation allows generation of high-frequency PWM for noise-sensitive motor drivers.
- Small 8-Pin Package: Minimizes PCB footprint for compact designs.
- Low Power Consumption: Active mode at 1MHz draws only 300µA, ideal for battery backup systems.
Automotive Sensor Interfaces
With 105°C operation and 5.5V tolerance, it can directly interface with 12V automotive signals (via resistor divider) for oil pressure or temperature monitoring.
Small Motor Drivers
Its 20MHz speed and PWM outputs can drive small brushed DC motors in toys or pumps with external MOSFETs.
LED String Controllers
Use the 8-pin package to control RGB LEDs with PWM for decorative lighting effects.
Battery Protection Circuits
Monitor cell voltage with the 10-bit ADC and control a FET for over/under-voltage protection in 2S Li-ion packs.
Industrial Limit Switches
Its robust I/O and WDT make it reliable for reading mechanical switches and sending status over a simple serial link.
Power Tool Accessories
The extended temperature range allows use in drill/driver attachments for speed control or torque sensing.
