The Microchip ATTINY816-SNR is a high-temperature, 8-bit AVR microcontroller in a 20-pin SOIC package. It features 8KB of flash, 512 bytes of RAM, and operates from 1.8V to 5.5V at speeds up to 20MHz. With integrated Brown-out Detection, Power-on Reset, and Watchdog Timer, it ensures robust operation from -40°C to +105°C. This MCU is designed for demanding industrial and automotive applications requiring compact size and reliable performance.
- Extended temperature range (-40°C to 105°C): Suitable for under-hood and industrial heat zones.
- Low voltage operation (1.8V): Enables single-cell battery designs.
- 20MHz performance: Handles complex control loops and fast I/O toggling.
- Large flash for size: 8KB allows complex firmware without external memory.
- Robust reset features: BOD and WDT enhance system reliability.
Industrial Sensor Hubs
With 8KB flash and 512B RAM, it can aggregate multiple analog/digital sensors in factory automation, using its 20MHz core for real-time data processing.
Automotive Body Electronics
The 105°C rating allows placement near engines for window lift or mirror control modules, with BOD ensuring stable operation under voltage transients.
Smart Home Controllers
Its 1.8V operation enables direct battery power in smart thermostats or door locks, while the 20-pin SOIC provides enough I/O for keypads and displays.
Portable Instrumentation
Low power consumption and wide voltage range make it ideal for handheld multimeters or data loggers, where the WDT prevents lockups during long deployments.
LED Matrix Displays
The 20MHz speed and PWM capabilities allow driving 8x8 LED matrices for signage, with the 512B RAM storing frame buffers.
Motor Control in Drones
Its fast ADC and PWM can handle ESC signals for small drone motors, with the extended temperature range supporting outdoor flight conditions.
