The ATTINY85-15ST from Microchip Technology is a compact 8-bit AVR MCU running at 16MHz. It offers 8KB flash and 512 bytes RAM in an 8-SOIC package. Operating from 2.7V to 5.5V, it includes brown-out detection, POR, PWM, and WDT. This MCU is a versatile choice for small-scale embedded projects and consumer electronics.
- High Integration in Small Package: 8KB flash and 512B RAM in an 8-pin SOIC, ideal for minimal designs.
- Wide Voltage Range: 2.7V-5.5V allows direct use with both 3.3V and 5V peripherals.
- Fast AVR Core: 16MHz throughput with most instructions executing in one clock cycle.
- Robust Protection: Brown-out reset and WDT prevent corruption in noisy environments.
- Easy to Prototype: SOIC package is breadboard-friendly with adapters, speeding development.
LED Lighting Effects
The 8KB flash and PWM channels allow complex color sequences and brightness control for RGB LEDs in decorative lighting.
Small Robotics
With 16MHz speed and 5V operation, it can drive servo motors and read IR sensors for line-following robots.
DIY Electronics Projects
The DIP/SOIC package and simple AVR architecture make it a favorite for hobbyist projects like digital thermometers or timers.
Automotive Accessories
Operating at 5V and -40°C to 85°C, it suits aftermarket LED strips or window tint controllers.
Sensor Conditioning
It can read analog sensors (e.g., thermistors) and output calibrated PWM signals for analog control loops.
Battery Chargers
The WDT and brown-out reset ensure safe charging algorithms for small Li-ion or NiMH batteries.
