The Microchip ATTINY416-SN is a low-power 8-bit AVR microcontroller in a 20-pin SOIC package. It operates from 1.8V to 5.5V and runs at up to 20MHz, providing 4KB of Flash and 256 bytes of SRAM. Integrated features include Brown-out Detect/Reset, Power-on Reset, and a Watchdog Timer, ensuring reliable operation in demanding environments. Its wide temperature range (-40°C to 105°C) suits industrial and automotive applications.
- Wide voltage range (1.8V-5.5V): Enables direct battery operation and 5V logic compatibility without level shifters.
- High temperature tolerance (-40°C to 105°C): Reliable in automotive and industrial enclosures where ambient heat exceeds 85°C.
- Integrated WDT and BOD: Prevents system lockups and resets the MCU safely during brown-out conditions, reducing field failures.
- 20MHz AVR core: Delivers 20 MIPS throughput, sufficient for real-time control loops and communication protocols.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage and low-power sleep modes allow the ATTINY416-SN to run directly from a coin cell or two AA batteries, extending operational life in IoT and remote monitoring devices.
Small Appliance Control
With 4KB Flash and a 20MHz AVR core, it can handle motor control loops, button debouncing, and LED sequencing in blenders, fans, and coffee makers, replacing larger 8-bit MCUs.
Automotive Interior Lighting
The -40°C to 105°C temperature range and robust Brown-out Reset make it reliable for interior ambient lighting controllers, seat position memory, and dashboard indicator modules.
Industrial Sensor Interface
Its 20-SOIC package provides enough I/O to interface with analog sensors, SPI/I2C peripherals, and a small display, while the WDT ensures recovery from firmware hangs in noisy factory environments.
Portable Medical Monitors
The low-voltage operation and small footprint enable compact designs for glucose meters or pulse oximeters, where the 4KB Flash stores calibration tables and the 256B SRAM handles real-time data buffering.
Smart Home Thermostats
Combining the 20MHz speed with multiple timers, it can read temperature sensors, drive a PWM fan, and communicate over UART with a Wi-Fi module, all within a 5V supply rail.
