The Microchip ATTINY85-20SF is an 8-bit AVR microcontroller with 8KB of flash memory and 512 bytes of SRAM. Operating at up to 20MHz with a 2.7V to 5.5V supply, it offers PWM, brown-out detection, and a watchdog timer. Its 8-SOIC package makes it a compact solution for embedded control.
- Generous Memory: 8KB flash allows for more complex programs than smaller AVRs.
- Low Power: Multiple sleep modes reduce current draw to microamps.
- Versatile I/O: PWM and analog comparator support various sensor and actuator interfaces.
- Proven Architecture: The AVR core is well-documented with extensive community support.
USB Peripheral Controllers
With 8KB flash, it can handle low-speed USB device enumeration and data transfer in keyboards or mice.
LED Matrix Displays
The 20MHz AVR core and PWM channels drive 8x8 LED matrices for scrolling text in signage.
Battery Management Systems
Its low-power sleep modes and 2.7V operation make it suitable for monitoring cell voltages in battery packs.
Model Rocket Telemetry
The small size and 8KB flash allow for logging altitude and temperature data in hobbyist rockets.
Smart Toys
It can control sound effects and motor movements in interactive toys with its rich peripheral set.
Home Automation Sensors
It interfaces with PIR sensors and relays to create simple motion-triggered lighting systems.
