The Microchip ATTINY84A-SSFR is an 8-bit AVR microcontroller in a 14-pin SOIC package, designed for extended temperature ranges up to 125°C. It features 8KB Flash, 512B SRAM, and operates from 1.8V to 5.5V at speeds up to 20MHz. Integrated peripherals include a 10-bit ADC, temperature sensor, PWM, and WDT. This automotive-grade variant ensures reliable performance in harsh environments.
- Extended Temperature Range (-40°C to 125°C): Meets automotive and industrial requirements for extreme environments.
- Ultra-Low Voltage Operation (1.8V): Enables direct battery operation with minimal power loss.
- Integrated Temperature Sensor: Eliminates external thermistors, saving BOM cost and PCB space.
- High-Speed 20MHz AVR Core: Provides efficient processing for real-time control tasks.
- Compact 14-SOIC Package: Ideal for space-constrained designs with moderate I/O needs.
Automotive Sensor Modules
The 125°C rating and 1.8V operation allow direct mounting on engine bays or exhaust systems for temperature and pressure sensing with minimal external components.
Battery Management in Portable Tools
Monitor cell voltage and temperature using the internal ADC and temp sensor, with PWM for cell balancing in 2-3 cell Li-ion packs.
LED Lighting Controllers
Drive RGB LEDs with PWM at 20MHz, using the 8-bit timers for smooth dimming and color mixing in architectural lighting.
Industrial Process Control
The wide voltage range and robust BOR make it reliable for 24V industrial loops with a simple regulator, controlling valves via PWM.
Wearable Health Monitors
Low 1.8V operation and small SOIC footprint enable compact designs for heart-rate or activity monitors with long battery life.
Smart Agriculture Nodes
Use the temp sensor and ADC to monitor soil moisture and ambient temperature, transmitting data via external RF modules.
